Cross-domain Authentication Mechanism Design and Research Based on the Mobile Internet

With the development of mobile communication, users put forward a higher security requirement in the process of intelligent mobile terminal to access different applications. A cross-domain authentication mechanism in the mobile Internet environment has been designed in this paper, which is B/S pattern. Firstly, the trust relationship between the Single Sign-on servers has been established by using SAML, then the design frame is Single Sign-on, as well as using HTTPS and ECC to encrypt data and the data transmissions. The user only needs to authenticate identity successfully in one trusted domain, then he can visit other trusted domains easily and does not need to authenticate identity again under the context that without exit. It is shown that a cross-domain authentication mechanism in the mobile Internet environment has been designed which raises the reliability of mobile terminal. This article uses identity-based encryption to calculate the public key and private key. Finally the paper verifies the proposed mechanism. Experiments show that this mechanism is convenient for the user's authentication, meanwhile it ensures the security and scalability of the system. It is proved that the cross-domain authentication mechanism has some reference meanings in the future research in this field.
