# Epic: Mature Brand Registration System
## Overview
Transform the current unidirectional brand registration system into a secure, bi-directional authentication and routing system that enables secure communication between Agency and Brand systems.
## Current State
- Simple request-response system
- Single endpoint for brand registration
- No persistent authentication mechanism
- No routing capabilities based on brand identity
## Requirements
### 1. Bi-directional Authentication
- [ ] Implement secure key generation and exchange during registration
- [ ] Design and implement key storage mechanism for both Agency and Brand systems
- [ ] Create key validation middleware for all API endpoints
- [ ] Implement key rotation and expiration policies
### 2. Brand Identity Management
- [ ] Create brand identity storage system
- [ ] Implement brand-to-key mapping database
- [ ] Design and implement key lookup service
- [ ] Add brand metadata storage (name, endpoints, status, etc.)
### 3. Message Routing System
- [ ] Design message routing architecture
- [ ] Implement brand-specific message routing
- [ ] Create message validation system
- [ ] Add message tracking and logging
### 4. API Security
- [ ] Implement API key validation middleware
- [ ] Implement request/response encryption
## Technical Considerations
### Security
- Key generation and storage must follow security best practices
- All keys must be encrypted at rest
- Implement proper key rotation mechanisms
- Add rate limiting and abuse prevention
### Performance
- Key lookup must be optimized for performance
- Message routing should be efficient
- Consider caching strategies for frequently accessed data
### Scalability
- System must handle multiple brands
- Design for horizontal scaling
- Consider future expansion of features
### Monitoring
- Implement comprehensive logging
- Create alerts for suspicious activities
## Acceptance Criteria
1. **Registration Flow**
- Brand initiates registration
- System generates secure key
- Key is securely transmitted to Brand
- Brand confirms key receipt
- System validates key storage
2. **Authentication**
- All API calls between Agency and Brand must include valid key
- System validates key on each request
- Invalid keys are rejected with appropriate error
- Expired keys trigger rotation process
3. **Routing**
- System correctly identifies brand from key
- Messages are routed to correct endpoints
- Failed routing attempts are logged
- System handles brand endpoint changes
4. **Security**
- All keys are encrypted at rest
- Keys are transmitted securely
- System detects and prevents key abuse
- Audit logs capture all key-related activities
## Dependencies
- Existing brand registration system
- Agency-to-Brand communication system
- Brand-to-Agency communication system
## Timeline
- Phase 1: Design and Architecture (2 weeks)
- Phase 2: Core Implementation (4 weeks)
- Phase 3: Security and Testing (2 weeks)
- Phase 4: Documentation and Deployment (1 week)
## Risks
- Key management complexity
- Performance impact of key validation
- Migration of existing brands
- Security vulnerabilities
## Success Metrics
- Successful key generation and exchange
- Zero key-related security incidents
- < 100ms key lookup time
- 99.9% message routing accuracy
