# BZZZ Role-Based Encryption System
|
||||
|
||||
## Overview
|
||||
|
||||
The BZZZ Role-Based Encryption System provides enterprise-grade security for the SLURP (Storage, Logic, Understanding, Retrieval, Processing) contextual intelligence system. This comprehensive encryption scheme implements multi-layer encryption, sophisticated access controls, and compliance monitoring to ensure that each AI agent role receives exactly the contextual understanding they need while maintaining strict security boundaries.

```
|
||||
|
||||
### Core Components
|
||||
|
||||
1. **RoleCrypto** (`role_crypto.go`): Main encryption/decryption engine with multi-layer encryption
|
||||
2. **KeyManager** (`key_manager.go`): Sophisticated key management with rotation and recovery
|
||||
3. **AccessControlMatrix** (`access_control.go`): Dynamic access control with policy evaluation
|
||||
4. **AuditLogger** (`audit_logger.go`): Comprehensive audit logging and compliance monitoring
|
||||
|
||||
## Security Features
|
||||
|
||||
### Multi-Layer Encryption
|
||||
|
||||
The system implements sophisticated multi-layer encryption where different roles receive different encryption layers:
|
||||
|
||||
- **Base Context Encryption**: Core context data encrypted with Age X25519
|
||||
- **Role-Specific Overlays**: Additional encryption layers based on role hierarchy
|
||||
- **Compartmentalized Access**: Strict isolation between role access levels
|
||||
- **Forward Secrecy**: Regular key rotation ensures forward secrecy
|
||||
|
||||
### Access Control Matrix
|
||||
|
||||
The access control matrix implements multiple security models:
|
||||
|
||||
- **RBAC (Role-Based Access Control)**: Traditional role-based permissions
|
||||
- **ABAC (Attribute-Based Access Control)**: Context-aware attribute evaluation
|
||||
- **ReBAC (Relationship-Based Access Control)**: Hierarchical role relationships
|
||||
- **Zero-Trust Architecture**: Never trust, always verify principle
|
||||
|
||||
### Key Management
|
||||
|
||||
Enterprise-grade key management includes:
|
||||
|
||||
- **Hierarchical Key Derivation**: PBKDF2-based key derivation from role definitions
|
||||
- **Automated Key Rotation**: Configurable rotation policies with grace periods
|
||||
- **Emergency Key Recovery**: Shamir secret sharing for disaster recovery
|
||||
- **Key Escrow**: Secure key backup and restoration capabilities
|
||||
|
||||
## Role Access Matrix
|
||||
|
||||
The system defines a comprehensive role hierarchy with specific access levels:
|
||||
|
||||
| Role | Access Level | Scope | Capabilities |
|
||||
|------|-------------|-------|--------------|
|
||||
| **Senior Architect** | Critical | System-wide | Full architecture access, all contexts |
|
||||
| **Project Manager** | Critical | Global coordination | All contexts for project coordination |
|
||||
| **DevOps Engineer** | High | Infrastructure | Infrastructure + backend + security contexts |
|
||||
| **Security Engineer** | High | Security oversight | All contexts for security review |
|
||||
| **Backend Developer** | Medium | Backend scope | Backend + API + database contexts |
|
||||
| **Frontend Developer** | Medium | Frontend scope | Frontend + UI + component contexts |
|
||||
| **QA Engineer** | Medium | Testing scope | Testing + quality + dev contexts |
|
||||
| **Data Analyst** | Low | Analytics scope | Data + analytics + reporting contexts |
|
||||
| **Intern** | Low | Training scope | Training + documentation contexts |
|
||||
| **External Contractor** | Low | Limited scope | Limited access contexts only |
|
||||
|
||||
### Access Level Definitions
|
||||
|
||||
- **Critical (Level 4)**: Highly classified information for master roles only
|
||||
- **High (Level 3)**: Sensitive information for decision-making roles
|
||||
- **Medium (Level 2)**: Confidential information for coordination roles
|
||||
- **Low (Level 1)**: Basic encrypted information for standard roles
|
||||
- **Public (Level 0)**: Public information, no encryption required
|
||||
|
||||

|
||||
[]string{"development", "security"}
|
||||
)
|
||||
|
||||
// Decrypt context with role-specific filtering
|
||||
decryptedContext, err := roleCrypto.DecryptContextForRole(

||||
|
||||
**Security Notice**: This system handles sensitive contextual information. Always follow security best practices, keep systems updated, and conduct regular security assessments. Report any security issues immediately to the security team.
|
||||
|
||||
**Compliance Notice**: This system is designed to meet multiple compliance standards. Ensure proper configuration and monitoring for your specific compliance requirements. Regular compliance audits are recommended.
|
||||
|
||||
**Performance Notice**: While the system is optimized for performance, encryption and access control operations have computational overhead. Plan capacity accordingly and monitor performance metrics in production environments.
