Efficient and Secure Remote Authenticated Key Agreement Scheme for Multi-server Using Mobile Equipment

This paper presents an efficient and secure authenticated key agreement scheme between remote users and multi-servers. The scheme can be used for mutual authentication and session key agreement between mobile devices and application servers, especially mobile phones equipped with IC (Integrated Circuit) chips such as a smart card or a USIM (Universal Subscriber Identity Module) card for 3G. And the scheme can be more easily implemented to mobile devices and efficiently used in mobile environment because of using light operation functions such as modular, hash and XOR.
