Identity-Based Edge Computing Anonymous Authentication Protocol

With the development of sensor technology and wireless communication technology, edge computing has a wider range applications. The privacy protection is great significance. In system, in order to ensure credibility source terminal data, mobile (MEC) needs verify signature node on data. During process, power devices such as terminals can easily become bottleneck system performance. Therefore, it very necessary improve efficiency through computational offloading. this paper proposes an identity-based anonymous authentication protocol. protocol realizes mutual obtains shared key by encrypting information. encryption algorithm implemented thresholded proxy ring signature. When large number offload computing, MEC set priority offloading tasks according user’s identity permissions, thereby improving efficiency. Security analysis shows that scheme guarantee anonymity unforgeability signatures. probability malicious forging equivalent cracking discrete logarithm puzzle. According analysis, case offloading, complexity significantly reduced, liberated, improved.
