Security Philosophy & Principles​

1.1 CORE SECURITY PRINCIPLES

Privacy by Design User data is private by default. No telemetry without explicit consent. Local-first architecture means most processing happens on-device, minimizing cloud exposure.

Defense in Depth Multiple layers of security. If one layer is compromised, others continue to protect. No single point of failure.

Principle of Least Privilege Every component, skill, and process gets minimum permissions needed to function. No blanket "superuser" access.

Zero Trust Architecture Never assume anything is secure. Always verify. Even internal components authenticate and validate each other.

Transparency Users always know when camera, microphone, or sensitive data is accessed. Visual and audible indicators mandatory.

User Control Users can disable any sensor, revoke any permission, and operate completely offline if desired.

Secure by Default Security features enabled by default. Users must explicitly weaken security if needed (not recommended).

1.2 SECURITY GOALS

Confidentiality

  • User data (personal info, memories, conversations) never leaves device without encryption and explicit consent
  • AI models and inference stay local by default
  • No eavesdropping on camera, microphone, or sensors by unauthorized parties

Integrity

  • Firmware cannot be tampered with (secure boot)
  • Data cannot be modified without detection (cryptographic signatures)
  • System configurations protected from malicious changes

Availability

  • System remains functional even under attack
  • DoS attacks mitigated
  • Graceful degradation if components fail

Authentication

  • Only authorized users can access the device
  • Strong user authentication (biometric + PIN)
  • Device-to-cloud mutual authentication

Authorization

  • Fine-grained permissions system
  • Skills cannot access resources beyond declared permissions
  • Dynamic permission revocation

Auditability

  • Security events logged (optional, user-controlled)
  • Forensic capability for incident investigation
  • Compliance with audit requirements (NDIS, enterprise)

1.3 REGULATORY COMPLIANCE

GROOT FORCE complies with:

  • GDPR (EU General Data Protection Regulation)
  • Privacy Act 1988 (Australia)
  • CCPA (California Consumer Privacy Act)
  • HIPAA (for health data, optional mode)
  • NDIS Practice Standards (for assistive devices)
  • ISO 27001 (Information Security Management)
  • SOC 2 Type II (for cloud services)

═══════════════════════════════════════════════════════════════════

SECURITY LAYERS ARCHITECTURE​

3.1 SEVEN-LAYER SECURITY MODEL

GROOT FORCE implements defense-in-depth with 7 security layers:

┌─────────────────────────────────────────────────────────────┐ │ LAYER 7: User Interaction Security │ │ (Biometric auth, permissions UI, privacy indicators) │ ├─────────────────────────────────────────────────────────────┤ │ LAYER 6: Application Security │ │ (Skill sandboxing, permission enforcement, API security) │ ├─────────────────────────────────────────────────────────────┤ │ LAYER 5: OS & Kernel Security │ │ (SELinux, seccomp, namespace isolation, signed modules) │ ├─────────────────────────────────────────────────────────────┤ │ LAYER 4: Data Security │ │ (Encryption at rest, encrypted storage, key management) │ ├─────────────────────────────────────────────────────────────┤ │ LAYER 3: Network Security │ │ (TLS 1.3, firewall, VPN, certificate validation) │ ├─────────────────────────────────────────────────────────────┤ │ LAYER 2: Firmware & Boot Security │ │ (Secure boot, verified boot, signed OTA updates) │ ├─────────────────────────────────────────────────────────────┤ │ LAYER 1: Hardware Security │ │ (TEE, hardware key storage, anti-rollback fuses) │ └─────────────────────────────────────────────────────────────┘

Each layer is independent. Compromise of one layer does not automatically compromise others.

3.2 LAYER INTERACTION

Example: User launches malicious skill attempting to steal data

  1. Layer 7: User grants camera permission (UI clearly shows this)
  2. Layer 6: Skill runs in sandbox, can only access camera API (not raw sensor)
  3. Layer 5: SELinux enforces that skill process cannot access other app data
  4. Layer 4: Even if skill escapes sandbox, user data is encrypted
  5. Layer 3: If skill tries to exfiltrate data, TLS ensures encrypted transport
  6. Layer 2: Firmware integrity prevents skill from installing backdoor
  7. Layer 1: Hardware-backed keys ensure skill cannot extract encryption keys

Result: Even sophisticated attack fails to steal significant data

═══════════════════════════════════════════════════════════════════

SECURE BOOT & FIRMWARE INTEGRITY​

4.1 SECURE BOOT CHAIN

Purpose: Ensure only authentic, unmodified firmware can run on device

Boot Sequence:

  1. Power-On

    • Hardware ROM (immutable) executes first
    • ROM contains root public key (burned in at factory)

  2. Bootloader Verification (Stage 1)

    • ROM verifies bootloader signature using root public key
    • If signature invalid - HALT (device unusable)
    • If valid - Execute bootloader

  3. Kernel Verification (Stage 2)

    • Bootloader verifies kernel signature
    • If signature invalid - HALT
    • If valid - Execute kernel

  4. System Partition Verification (Stage 3)

    • Kernel verifies system partition (dm-verity)
    • Cryptographic hash tree ensures no modification
    • If hash mismatch - Boot to recovery mode

  5. OS Boot

    • User space processes start
    • SELinux policies loaded
    • All system services verified before execution

4.2 VERIFIED BOOT (ANDROID VERIFIED BOOT 2.0)

GROOT FORCE uses AVB 2.0 for partition integrity:

  • Hash trees computed for all read-only partitions (system, vendor, boot)
  • Hash trees signed with device-specific key
  • Bootloader verifies hash trees before mounting partitions
  • Any modification detected - Boot warning or failure (depending on policy)

Rollback Protection:

  • Anti-rollback counter in hardware fuses
  • Prevents downgrade to older (vulnerable) firmware versions
  • Incremented with each OTA update

4.3 FIRMWARE SIGNING

All firmware images signed with private key (held by GROOT FORCE only):

Signing Process:

  1. Build firmware image
  2. Compute SHA-256 hash
  3. Sign hash with RSA-4096 private key (or ECDSA P-384)
  4. Append signature to image
  5. Distribute signed image

Verification Process (on device):

  1. Receive firmware image
  2. Extract signature
  3. Compute SHA-256 hash of image
  4. Verify signature using public key (stored in secure storage)
  5. If valid - Install, else reject

Key Storage:

  • Private key: HSM (Hardware Security Module) at GROOT FORCE HQ

  • Never leaves HSM

  • Requires multi-person authorization to use

  • Public key: Embedded in bootloader (read-only)

4.4 OTA UPDATE SECURITY

OTA updates follow strict security protocol:

  1. Update Availability Check

    • Device contacts update server over TLS 1.3
    • Certificate pinning ensures talking to real GROOT FORCE server

  2. Update Download

    • Update package downloaded over HTTPS
    • Includes:
      • Firmware image
      • Metadata (version, changelog, dependencies)
      • Cryptographic signature

  3. Signature Verification

    • Device verifies signature before installation
    • Reject if signature invalid

  4. Version Check

    • Device checks anti-rollback counter
    • Reject if update version older than current

  5. Installation

    • Update applied to inactive partition (A/B system)
    • Device reboots into new partition
    • If boot fails - Automatic rollback to previous partition

  6. Post-Update Verification

    • Device verifies new firmware integrity
    • If corrupt - Rollback

User Control:

  • Users can defer updates (not forced)
  • Users can disable auto-download (manual only)
  • Enterprise can control update policy centrally

═══════════════════════════════════════════════════════════════════

AUTHENTICATION & AUTHORIZATION​

5.1 USER AUTHENTICATION

GROOT FORCE supports multiple authentication methods:

Method 1: Biometric (Primary)

  • Facial recognition (using front camera)
  • Voice recognition (using microphone)
  • Gait analysis (using IMU - experimental)

Enrollment:

  1. User sets up biometric during initial setup
  2. Multiple samples captured (face from different angles, voice in different conditions)
  3. Biometric template created and stored in TEE (Trusted Execution Environment)
  4. Template never leaves device

Verification:

  1. User attempts to unlock device
  2. Camera/microphone captures sample
  3. Sample compared to template in TEE
  4. If match (within threshold) - Unlock

Security:

  • Biometric templates encrypted
  • Stored in TEE (hardware-isolated)
  • Cannot be extracted even with root access
  • Liveness detection (prevent photo/recording attacks)

False Accept Rate (FAR): <1 in 50,000 False Reject Rate (FRR): <1 in 20

Method 2: PIN (Backup)

  • 6-digit PIN (minimum)
  • Stored as salted hash (bcrypt, cost factor 12)
  • 5 failed attempts - Lockout (1 minute)
  • 10 failed attempts - Lockout (10 minutes)
  • 20 failed attempts - Full lockout (requires factory reset)

Method 3: Recovery Code (Emergency)

  • One-time use code generated during setup
  • Printed/saved offline by user
  • Can be used if biometric and PIN both fail (e.g., device malfunction)

5.2 DEVICE AUTHENTICATION (TO CLOUD)

When device connects to GROOT FORCE Cloud, mutual authentication required:

Client Authentication (Device - Cloud):

  • Device has unique certificate issued during manufacturing
  • Certificate signed by GROOT FORCE CA (Certificate Authority)
  • Device presents certificate during TLS handshake
  • Cloud verifies certificate chain

Server Authentication (Cloud - Device):

  • Cloud presents TLS certificate
  • Device verifies certificate chain
  • Certificate pinning: Device only trusts specific GROOT FORCE certificates (prevents MITM even with compromised CA)

API Authentication:

  • OAuth 2.0 tokens for API access
  • Tokens short-lived (1 hour)
  • Refresh tokens used to obtain new access tokens
  • Refresh tokens can be revoked (remote logout)

5.3 AUTHORIZATION & PERMISSIONS

GROOT FORCE uses fine-grained permission system (similar to Android):

Permission Categories:

Normal Permissions (Auto-granted):

  • Internet access
  • Bluetooth
  • Wi-Fi
  • Read system info
  • Display HUD

Dangerous Permissions (Require user approval):

  • Camera
  • Microphone
  • Location (GPS)
  • Sensors (IMU, ToF, LiDAR)
  • User data (memory, RAG, contacts)
  • Health sensors

System Permissions (Require signature):

  • System settings
  • Firmware update
  • Factory reset
  • Install/uninstall skills

Permission Granting:

  1. Skill declares required permissions in manifest
  2. At install time, user shown permission list
  3. At runtime (first use), user prompted for dangerous permissions
  4. User can grant/deny individually
  5. User can revoke permissions anytime in settings

Permission Enforcement:

  • OS kernel enforces permissions (SELinux)
  • API calls check permissions before execution
  • Unauthorized access - Error returned to skill
  • Repeated unauthorized attempts - Skill quarantined

5.4 SKILL AUTHENTICATION

Skills distributed through GROOT FORCE Skill Store must be signed:

Code Signing:

  1. Developer builds skill
  2. Developer signs skill package with their private key
  3. Developer uploads to store
  4. Store verifies developer identity
  5. Store adds secondary signature (GROOT FORCE signature)
  6. User downloads skill
  7. Device verifies both signatures before installation

Untrusted Sources:

  • Users can enable "Install from Unknown Sources" (dev mode)
  • Warning displayed: "This skill is not verified. Install at your own risk."
  • Skill still runs in sandbox (cannot harm system)

Revocation:

  • If skill found malicious, GROOT FORCE can revoke signing certificate
  • Device checks revocation list during install
  • Already-installed malicious skills can be remotely disabled

═══════════════════════════════════════════════════════════════════

DATA ENCRYPTION (AT REST)​

6.1 FULL-DISK ENCRYPTION (FDE)

All user data partitions encrypted using:

  • Algorithm: AES-256-XTS
  • Key derivation: PBKDF2-HMAC-SHA256 (100,000 iterations)
  • Key storage: TEE (Trusted Execution Environment)

Encryption Key Hierarchy:

Master Key (MEK - Master Encryption Key) └─> Derived from user PIN/biometric └─> Stored in TEE, wrapped by hardware key └─> Used to encrypt DEK

Data Encryption Key (DEK) └─> Randomly generated (256-bit) └─> Encrypted by MEK └─> Used to encrypt actual data

Decryption Flow:

  1. User unlocks device (biometric/PIN)
  2. TEE verifies credentials
  3. TEE unwraps MEK
  4. MEK decrypts DEK
  5. DEK mounts encrypted partitions
  6. User data accessible

Security:

  • DEK never stored in plaintext (always encrypted by MEK)
  • MEK never stored in plaintext (wrapped by hardware key in TEE)
  • Hardware key never leaves TEE
  • Cold-boot attacks mitigated (keys zeroized on power-off)

6.2 FILE-BASED ENCRYPTION (FBE)

In addition to FDE, GROOT FORCE uses file-based encryption for granular control:

Each user file/directory can have individual encryption key:

  • Personal documents: Encrypted with user credential-derived key
  • Shared documents: Encrypted with device key (accessible before unlock)
  • App data: Each app has isolated keystore

Use Cases:

  • Notifications can work before device unlock (encrypted with device key)
  • User photos/videos fully protected (encrypted with user key)
  • Enterprise: Different encryption for work profile vs personal profile

6.3 DATABASE ENCRYPTION

SQLite databases (used for RAG, user memory, system settings) encrypted using:

  • SQLCipher (open-source SQLite encryption extension)
  • AES-256-CBC
  • Per-database encryption keys (derived from master key)

Operations:

  • Queries work normally (transparent encryption/decryption)
  • Keys held in memory only while database open
  • Database closed - Key cleared from memory

6.4 SECURE KEY STORAGE

Encryption keys stored in TEE:

Trusted Execution Environment (TEE):

  • Hardware-isolated secure CPU mode (ARM TrustZone or equivalent)
  • Separate from main OS
  • Cannot be accessed by user space or even kernel
  • Keys generated and used inside TEE, never exported

Key Generation:

  • Hardware RNG (Random Number Generator) used
  • Entropy from multiple sources (thermal noise, etc.)
  • Keys meet NIST SP 800-90B requirements

Key Backup:

  • Users can optionally backup keys to GROOT FORCE Cloud (encrypted)
  • Backup encrypted with user password (never sent to cloud in plaintext)
  • Enables device recovery if lost/damaged

6.5 SECURE DELETION

When user deletes data, secure erasure performed:

Method:

  • Overwrite deleted blocks with random data (1-3 passes)
  • Cryptographic erasure: Delete encryption key (data unrecoverable without key)

Factory Reset:

  • All encryption keys deleted from TEE
  • User partitions cryptographically wiped
  • Device returned to factory state
  • Previous data unrecoverable (even with forensic tools)

═══════════════════════════════════════════════════════════════════

DATA ENCRYPTION (IN TRANSIT)​

7.1 TLS 1.3 FOR ALL INTERNET TRAFFIC

All network communication uses TLS 1.3 (minimum):

  • Cipher suites: AES-256-GCM, ChaCha20-Poly1305
  • Key exchange: ECDHE (Elliptic Curve Diffie-Hellman Ephemeral)
  • Signature: RSA-2048 or ECDSA P-256
  • Perfect Forward Secrecy (PFS) ensured

Certificate Validation:

  • Full certificate chain validation
  • CRL (Certificate Revocation List) checked
  • OCSP (Online Certificate Status Protocol) supported
  • Certificate pinning for GROOT FORCE Cloud services

Certificate Pinning:

  • Device has hardcoded hash of GROOT FORCE server certificates
  • During TLS handshake, server certificate hash verified
  • If mismatch - Connection refused (even if certificate otherwise valid)
  • Prevents MITM attacks even if CA compromised

7.2 VPN SUPPORT

Users can route all traffic through VPN:

Built-in VPN Protocols:

  • WireGuard (recommended, modern, fast)
  • OpenVPN
  • IPSec/IKEv2

VPN Configuration:

  • Import config file (from VPN provider)
  • Or manual setup (server address, credentials)

VPN Enforcement:

  • "Always-On VPN" mode: All traffic must go through VPN
  • If VPN disconnected - Internet blocked (prevents leaks)
  • Exception: Emergency services always allowed

Use Cases:

  • Privacy-conscious users
  • Travelers in restrictive countries
  • Enterprise: Mandatory VPN for company data access

7.3 BLUETOOTH SECURITY

Bluetooth 5.3 with security features:

Pairing:

  • Secure Simple Pairing (SSP) with ECDH
  • Numeric comparison or passkey entry
  • Protection against MITM attacks

Encryption:

  • AES-128-CCM for all Bluetooth data
  • Link key negotiated during pairing
  • Link key stored in secure storage

BLE (Bluetooth Low Energy):

  • LE Secure Connections (Bluetooth 4.2+)
  • ECDH-based pairing
  • AES-128-CCM encryption

Attack Mitigations:

  • BlueBorne (CVE-2017-0781, etc.): Patched
  • KNOB (Key Negotiation of Bluetooth): Enforced minimum key length (16 bytes)
  • Bluetooth turned off when not in use (power saving + security)

7.4 WI-FI SECURITY

Wi-Fi security best practices:

WPA3 Support:

  • WPA3-Personal (SAE - Simultaneous Authentication of Equals)
  • Protection against offline dictionary attacks
  • Forward secrecy (even if PSK compromised, past traffic safe)

WPA2 Support (Fallback):

  • WPA2-AES (CCMP mode)
  • WPA2-PSK for home networks
  • WPA2-Enterprise for corporate networks (802.1X)

Attack Mitigations:

  • KRACK (Key Reinstallation Attack): Patched
  • Evil Twin attacks: MAC address validation (where possible)
  • Captive portal warnings: "This network may not be secure"

Recommendations to Users:

  • Avoid open Wi-Fi networks
  • Use VPN on public Wi-Fi
  • Verify network name before connecting

═══════════════════════════════════════════════════════════════════

HARDWARE SECURITY​

9.1 TRUSTED EXECUTION ENVIRONMENT (TEE)

GROOT FORCE SoC includes hardware TEE (ARM TrustZone):

TEE Functions:

  • Cryptographic key storage
  • Biometric template storage
  • Secure boot verification
  • Trusted UI (for entering PIN, viewing sensitive data)

TEE Isolation:

  • Separate CPU mode (privileged)
  • Separate memory region (cannot be accessed by normal OS)
  • Hardware-enforced isolation (even kernel cannot access TEE)

TEE Software:

  • Minimal trusted OS (e.g., OP-TEE, Trusty)
  • Open-source (auditable)
  • Signed and verified during boot

9.2 HARDWARE-BACKED KEY STORAGE

Encryption keys stored in hardware:

Secure Element (Optional, Premium Models):

  • Dedicated chip for key storage (e.g., NXP EdgeLock SE050)
  • Keys generated inside chip, never extracted
  • Tamper-resistant (physical attacks destroy keys)
  • FIPS 140-2 Level 3 certified

OTP (One-Time Programmable) Memory:

  • Fuses programmed at factory with device-unique key
  • Cannot be modified or read externally
  • Used for root of trust

9.3 ANTI-TAMPER PROTECTIONS

Physical Security:

Standard Models:

  • Continuous health testing (NIST SP 800-90B)
  • Entropy pool: 256 bits minimum

Seed Sources:

  • CPU jitter
  • Sensor noise (IMU, ADC)
  • Thermal noise

Used For:

  • Encryption key generation
  • Nonce generation
  • Session tokens
  • Challenge-response authentication

═══════════════════════════════════════════════════════════════════

SOFTWARE SECURITY​

10.1 OS HARDENING (SELINUX)

GROOT FORCE uses SELinux (Security-Enhanced Linux) in enforcing mode:

Mandatory Access Control (MAC):

  • Every process, file, socket has security label
  • SELinux policy defines what each label can access
  • Even root user constrained by SELinux

Policy:

  • Skills run in isolated domains
  • Skills cannot access other skills' data
  • Skills cannot access system files
  • Skills cannot modify OS

Example Policy Rule: allow skill_domain camera_device:chr_file { read write ioctl open };

This allows skill to access camera, but not microphone or storage.

10.2 SANDBOXING & ISOLATION

Skills run in strict sandboxes:

Sandbox Mechanisms:

  • Linux namespaces (PID, network, mount, IPC)
  • cgroups (resource limits: CPU, memory, I/O)
  • seccomp-bpf (syscall filtering)

Skill Isolation:

  • Each skill runs in separate Linux user (UID)
  • Separate filesystem namespace (chroot-like)
  • Separate network namespace (no internet unless granted)
  • Separate IPC namespace (cannot talk to other skills)

Resource Limits:

  • CPU: Max 50% of one core (prevents crypto mining)
  • Memory: Max 512 MB (prevents memory exhaustion)
  • Storage: Max 100 MB (prevents storage filling)
  • Network: Max 1 MB/s (prevents bandwidth abuse)

Exceeding Limits:

  • Skill throttled or killed
  • User notified
  • Persistent abuse - Skill uninstalled

10.3 CODE SIGNING & INTEGRITY

All executable code verified before execution:

System Code:

  • SQL injection prevention (parameterized queries)
  • XSS prevention (output encoding)
  • CSRF protection (for web UI)

12.3 DATA ENCRYPTION (CLOUD)

User data encrypted at rest and in transit:

At Rest:

  • Database encryption (AES-256)
  • File storage encryption (S3 server-side encryption with KMS)
  • Backups encrypted

In Transit:

  • TLS 1.3 for all API calls
  • Certificate pinning (client-side)

Key Management:

  • AWS KMS (Key Management Service)
  • Keys rotated annually
  • Master key in HSM (Hardware Security Module)

12.4 CLOUD ACCESS CONTROL

Strict access control:

  • No cross-user data access (enforced by API logic + database constraints)

Admin Access:

  • Minimal admins (2-3 people)
  • Admin actions logged (audit trail)
  • Privileged access requires MFA (multi-factor authentication)
  • Admin cannot access user data without explicit user consent + legal basis

Third-Party Access:

  • No third parties have access to cloud infrastructure

═══════════════════════════════════════════════════════════════════

SKILL SANDBOXING & PERMISSIONS​

13.1 SKILL SANDBOX ARCHITECTURE

Skills run in isolated environments:

Container-Like Isolation:

  • Separate Linux user (UID)
  • Separate filesystem (chroot jail)
  • Separate process namespace (cannot see other processes)
  • Separate network namespace (isolated networking)

Resource Limits:

  • CPU: 50% of one core max
  • Memory: 512 MB max
  • Storage: 100 MB max
  • Network: 1 MB/s max

System Call Filtering (seccomp):

  • Whitelist of allowed syscalls
  • Dangerous syscalls blocked (e.g., ptrace, mount, reboot)

13.2 PERMISSION SYSTEM

Skills declare permissions in manifest:

manifest.json:

{
  "skill_name": "Photo Capture",
  "version": "1.0.0",
  "permissions": [
    "CAMERA_READ",
    "STORAGE_WRITE"
  ]
}

Permission Grant Flow:

  1. User installs skill
  2. Skill requests permissions (shown in install prompt)
  3. User reviews and approves/denies
  4. At runtime, skill API calls check permissions
  5. Unauthorized calls - Error returned

Runtime Permission Prompts:

  • First time skill uses dangerous permission - Popup
  • User can: Allow, Deny, Always Allow, Never Allow

Permission Revocation:

  • User can revoke permissions anytime in settings
  • Skill notified (can request permission again)

13.3 SKILL COMMUNICATION RESTRICTIONS

Skills cannot directly communicate with each other:

Inter-Skill Communication (ISC):

  • Prohibited by default
  • If needed, use system-mediated API:
    • Skill A sends intent to system
    • System asks user: "Skill A wants to send data to Skill B. Allow?"
    • If allowed - System forwards data to Skill B

Reasoning:

  • Prevent data leakage
  • Prevent collusion (two malicious skills working together)

13.4 SKILL UPDATES

Skill updates follow security protocol:

Update Signing:

  • Updates must be signed by same developer key as original
  • Version number must increment (prevent rollback)

Update Review:

  • If new permissions requested - User must approve
  • If code significantly changed - Optional re-review by store

═══════════════════════════════════════════════════════════════════
