The proliferation of intelligent swarm systems demands secure large-scale authentication. Abu Bakar et al.'s DPUAUT protocol integrates SmartNiC and PUFs but lacks thorough security validation. This study systematically reassesses DPUAUT, identifying three critical vulnerabilities: replay attacks via session ID reuse, identity forgery through PUF CRP reuse, and weak session-key derivation lacking forward secrecy. We propose a hardened redesign incorporating one-time nonce binding, PUF CRP renewal, and ECDH-based ephemeral key derivation. Evaluations across 10–500 nodes confirm the improved protocol effectively mitigates these vulnerabilities while preserving its lightweight authentication structure.
