Mediated IBC-Based Management System of Identity and Access in Cloud Computing

Cloud computing is a new technology that provides consumers dramatically scalable and virtualized resources, bandwidth, software and hardware on demand. However, cloud computing introduces serious security problems. One of these major security concerns is the management of access and identities of different entities involved in such an environment. This paper proposes a new system for Identity and Access Management (IAM) based on combining the techniques of Identity-Based Cryptography (IBC) and security mediated cryptography with the Trusted Cloud (TC) to facilitate the secure management and access control for cloud computing. IBC is an interesting choice for IAM as it significantly reduces the key management complexity. On the other hand, mediated cryptography enables system administrators to achieve access control in a fine-grained manner, while a TC can provide a Single Sign-On (SSO) ability to users. The paper also presents the results of the developed prototype implementation of the proposed IAM system
