A Proxy Signature Scheme With Public Verifiability For Nac

Considering the importance of the Network Admittance Control (NAC) on the access of secret data from web cameras, a signature-based NAC scheme is presented, along with explicit authorization processes. Once a dispute on the NAC appears, robots can track down the real identity of the proxy signer and efficiently stop abuse NAC. With respect to the theoretical validation, security assessment and a numerical simulation, the proposed scheme can achieve both security and efficiency of NAC with the help of the proxy manager of group signature.
