An Advanced ECC Dynamic ID-Based Remote Mutual Authentication Scheme for Cloud Computing

"Cloud" is a common metaphor for an Internet accessible infrastructure which is hidden from users. Cloud Computing makes data truly mobile and a user can simply access a chosen cloud with any internet accessible device. Miller(1986) and Koblitz (1987) proposed an Elliptic Curve Cryptosystem (ECC) based mechanism to provide an authentication mechanism for a user can access remote server secretly. Recently, ECC based remote authentication scheme has been used for cloud Internet and remote devices. For instance, Yang and Change proposed an ID-based remote mutual authentication with key agreement scheme for remote devices on Elliptic Curve Cryptosystem in 2009. However, in this paper, we found that their scheme still is vulnerable to insider attack and impersonation attack. Therefore, we proposed an ECC dynamic ID-Based remote mutual authentication scheme for remote devices to solve the issues. Furthermore, we analyzed our scheme to show that our scheme is more secured to authenticate users and remote servers for cloud computing.
