Mobile ad hoc network access authentication mechanism based on rotation election and two-factor aggregation

With the continuous development and progress of computer network communication technology, mobile ad hoc networks (MANET) with strong indestructibility and no fixed infrastructure have become one of the new hot research areas in the academic community. However, due to the open wireless channel and unpredictable changes of network topology, mobile ad hoc networks are susceptible to security threats such as identity spoofing, identity tracing, and DoS attacks, and face security problems that cannot be ignored. Therefore, it is necessary to design a trusted access authentication scheme to authenticate the identity of unknown nodes and ensure the security of connected nodes. In this paper, the Certificate Authority rotation election algorithm based on improved DPoS and access authentication mechanism based on dual identity factor aggregation are proposed, which improve the authentication efficiency and the anti-attack ability of the authentication system, and ensure the security and stability of the network. At the same time, the authentication information is uploaded to the blockchain to ensure the security and immutability of the data. The safety analysis and performance simulation experiments show that the proposed scheme has high safety and good performance.
