초록
This study conducts a security vulnerability analysis of a blockchain-based cloud-fog collaborative authentication protocol in smart home environments. The proposed protocol integrates elliptic curve encryption and zero-knowledge proofs to ensure user anonymity and prevent impersonation and replay attacks. Additionally, it introduces role-based access control (RBAC) to mitigate insider threats and ensures perfect forward secrecy for each session. Future research will explore hybrid blockchain consensus mechanisms and post-quantum cryptography to further enhance the protocol's resilience.
