A Secure and Efficiency ID-Based Authenticated Key Agreement Scheme Based on Elliptic Curve Cryptosystem for Mobile Devices
In 2009, Yang and Chang proposed an ID-based remote mutual authentication with key agreement scheme on Elliptic Curve Cryptosystem (ECC). Based upon ID-based concept, Yang and Chang scheme (YC scheme) does not require additional computations for certificate and is not constructed by bilinear-pairings, which is an ex-pensive operation on elliptic curve. In addition, YC scheme not only provides mutual authentication but also supports a session key agreement between the user and the server. Therefore, YC scheme is more efficient and practical than the related works.
