In these days all businesses trying to use global applications on cloud computing infrastructure to reduce their costs and also decentralize their application.This movement also causes more security risks over the unbounded cloud environment.Therefore, accessing enterprise information for an unwanted user will be more than other environments.Thus, the proposed Identity Management System (IDMS) tries to preserve security in communication between clients and server over cloud computing.The proposed method suggested token based Identity Management and also enhanced privacy by adding one.Dual Certificate Manager (DCM) block is a replacement for a combination of symmetric and asymmetric cryptography, which is commonly used for SSL/TLS protocol to immune data transmission, uses asymmetric cryptography in both participants.Furthermore, for more privacy and invulnerability DCM uses Elliptic Curve Cryptography (ECC) as asymmetric cryptography algorithm.
