Security Architecture

BAR Security Architecture Diagram

BAR Security Architecture Overview

Encryption System

  • AES-256 in GCM mode for authenticated encryption
  • Unique encryption key for each file
  • Key derivation using PBKDF2-HMAC-SHA256 with high iteration counts
  • Hardware-binding option to prevent access from unauthorized devices
  • Secure memory handling to prevent key exposure

Self-Destruction Mechanisms

  • Time-based: Files automatically delete after a specified time period
  • Access-count: Files delete after being accessed a certain number of times
  • Deadman switch: Files delete if not accessed within a specified period
  • Anti-brute force: Files delete after multiple failed password attempts
  • Secure deletion using multi-pass overwrite techniques compliant with DoD standards

Secure Storage

  • All data stored locally in the ~/.bar directory with proper encryption
  • No plaintext storage of sensitive information
  • Secure key management with memory protection
  • Blacklist system to prevent reimporting of deleted sensitive files
  • File integrity verification using digital signatures

Anti-Tampering Protection

  • Runtime integrity checks to detect application tampering
  • Hardware ID verification to prevent unauthorized device access
  • Secure random number generation for cryptographic operations
  • Protection against timing attacks in cryptographic implementations
  • Memory protection to prevent sensitive data exposure
