Recently, due to the rising and flourishing of the computer networks development. Application of smart card becomes even more and more universality and functionality. Hence, the remote user authentication scheme over an insecure channel gets a topic for discussion. Owing to the Internet is a virtual network environment. When a user wants to access resource and service for any remote server, several important information of personal will deliver over insecure public network. Event of secret information stolen by intruder easily occurred, even the identity of legal user to access network resource faked. Therefore, it claims the remote user authentication protocol to authenticate the validity between the two parties of a user and a server. This thesis focuses on remote user authentication mechanism with smart cards, and then proposes two user authentication protocols with smart cards. Moreover, it achieves the merit of low-computation cost and low-amount transmission. In order to reduce the computation cost and the amount of information transmission for smart cards, this thesis gives up the traditional public key cryptosystem based on RSA and ElGamal. Our propose methods can protect user’s secret information over public network and can generate the common session key during mutual authentication between two parties of a user and a server. In addition, a user can freely update password in this proposed protocol. In this thesis, the required operations are only few hashing operations, simple exclusive-or operations, and nonce-based number. Since the properties of the low-computation cost and the low-amount transmission, the proposed proposal can greatly reduce the computation cost and lower the amount of communication for both the user and the server. Moreover, this proposed protocol also provides complete functionality and suitability for the user with smart cards upon wireless network services. Overall, this dissertation is to investigate more efficient and low communications in wireless networks. We want the results of proposed schemes will be more attractive to many applications.
