An elliptic curve authenticated key exchange based approach to key infrastructure

Introduces an elliptic curve analogue to the existing exponential/encrypted key exchange methods, with a view to optimizing such techniques for implementation within a mobile (wireless) framework. The complete scheme of how these methods can be adopted, along with the other security components (e.g. proxies) in the existing infrastructure is analysed. In this paper, we discuss the complete key setup procedures and various scenarios describing how confidential communication is performed once the key has been set up and mutual authentication achieved. The advantages of the proposed schemes are discussed
