39. SEMOPIAS: A Novel Secure and Efficient Mutual Open PKI Identity Authentication Scheme for Mobile Commerce

Although the mobile commerce has wide prospect, it has to face with huge challenges because of potential security risks, privacy problems and efficiency due to its limitations of processing capability, and storage space and power supply in mobile terminal. The secure and efficient open PKI (Public Key Infrastructure) identity authentication scheme is one of the possible solutions in secure identity authentication of the mobile commerce. In this paper, we propose a novel secure and efficient mutual open PKI identity authentication scheme, named SEMOPIAS, to solve the problems of validity, one-time use of identification and unauthorized application system in open PKI identity authentication scheme. Analysis and evaluation are performed to demonstrate that the SEMOPIAS achieves stronger security and higher efficiency by simplifying the message format and optimizing the authentication processes. Especially, the advantages of the SEMOPIAS will be achieved more significantly when there are multiple clients or merchants participated in the scheme.
