 We take security seriously. If you discover a security vulnerability, please follow these steps:
 
 1. **Do Not** create a public GitHub issue
-2. Email security@example.com with details about the vulnerability
+2. Email security@security.dynamic-neural-network-refinement.com with details about the vulnerability
 3. Allow up to 48 hours for an initial response
 4. Work with us to responsibly disclose the issue
 
 ## Security Measures
 
+- Improved token generation for client authentication in federated learning.
+- Encryption key is now read from an environment variable with length validation.
+- Trust score mechanism to mitigate malicious client updates.
 - All dynamic model updates are cryptographically signed
 - Continuous security scanning in CI/CD pipeline
 - Regular dependency updates and vulnerability checks
