A Mobile Terminal Authentication Scheme Based on Symmetric Cryptographic Mechanisms

In order to achieve secure access to mobile applications, in this paper, authentication scheme of application layer based on symmetric cryptography is proposed. In the scheme, seed key are pre-stored on both sides of the authentication. In the authentication process, one-time authentication code is generated by authentication protocol in SD key and certificated in authentication center to confirm the mobile user's identity. Hardware encryption devices are utilized to store and protect seed key and authentication protocol by security mechanism of encryption devices. Analyses show that the scheme is efficient and safe.
