Lina Zhang, Junhan Yang, Qi Mu, Zhuo Zhang


With the development of the Internet and the rise of e-commerce, online transactions and related business has greatly development as the mainstay of its convenience and high efficiency. The number of users and the total amount of transactions are tremendous increased. However, it also brings about a series of secure payment problems. This has hindered the development of online banking. Hence new models and methods are needed to solve these problems. Towards this purpose, by introducing the identity-Based cryptography with mediated RSA, we present a modified model to authenticate clients for the online payment through utilizing a semi-trust scheme. Then the details of the basic security properties, the aggressive behavior analysis and the security advantage of the proposed model are discussed in the paper.
