Description
Summary:Abstract Due to the problems that International Mobile Subscriber Identity is not encrypted during transmission, key disclosure, and high authentication overhead in Evolved Packet System‐Authentication and Key Agreement, the next generation of high‐speed railway Long‐Term Evolution for Railway train ground authentication protocol, this paper describes the improved Secure Remote Password algorithm and two‐way heterogeneous Long‐Term Evolution for Railway authentication key agreement scheme. First, the improved Secure Remote Password algorithm is used to encrypt the message transmission between User Equipment and Mobility Management Entity, solving the problem of International Mobile Subscriber Identity being not encrypted during transmission. Then, a two‐way heterogeneous digital signature method of Public Key Infrastructure and Identity‐Based Cryptosystem is proposed to authenticate and negotiate with the Mobility Management Entity and Home Subscriber Server, which improves the security of the root key and can effectively prevent man in the middle, replay and other attacks. Finally, in the research results, the random oracle model is used to verify, and the results show that our method is superior to the comparison method in security and authentication cost, and can meet the Long‐Term Evolution for Railway communication requirements.
