Authentication scheme based on smart card in multi-server environment

For authentication schemes based on smart card in multi-server environment, there is a common problem—the parameters stored in a user’s smart card linearly increase with the number of the registered servers without involving registration center in helping with authentication process. Therefore, in order to save storage cost and raise efficiency, an authentication scheme based on smart card is proposed in multi-server environment. In the proposed scheme, a user only needs one time registration, and keeps a password to realize the authentication with different servers without involving the registration center in helping with authentication process. The server is unnecessary to store any users information to achieve authentication between the users and the server. Moreover, the security of the proposed scheme is proved by Burrows–Abadi–Needham logic. The security analysis and the performance analysis show the proposed scheme is secured against various well known attacks, and has lower communication cost, computation cost and storage cost compared with several related schemes.
