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