DeCube implements multiple layers of cryptographic security:

• ECDSA: Used for digital signatures with P-256 curve
• Key Rotation: Automatic key rotation every 90 days
• Hardware Security Modules: Support for HSM integration
• Key Backup: Encrypted key backups with Shamir's Secret Sharing

• AES-256-GCM: For data at rest encryption
• TLS 1.3: For data in transit with perfect forward secrecy
• X25519: For key exchange in TLS handshakes

• SHA-256: For content addressing and integrity checks
• BLAKE3: For high-performance hashing (future implementation)

• PBFT-inspired: Global consensus tolerates up to 1/3 faulty nodes
• Validator Quorum: Requires 2/3+ agreement for transaction finality
• Slashing: Penalties for malicious validator behavior

• RAFT: Strong consistency within individual clusters
• Leader Election: Secure leader selection with timeout mechanisms
• Log Replication: Cryptographically signed log entries

• Mutual TLS: All peer communications use mTLS
• Certificate Authority: Private CA for certificate management
• Certificate Revocation: Online Certificate Status Protocol (OCSP)

• Rate Limiting: Configurable rate limits on all APIs
• Traffic Shaping: QoS for different traffic types
• Circuit Breakers: Automatic failure detection and isolation

• Merkle Trees: Cryptographic integrity verification
• Content Addressing: SHA-256 based addressing prevents tampering
