Abstract:


Cloud computing is the emerging technology providing IT as a utility through internet. The benefits of cloud computing are but not limited to service based, scalable, elastic, shared pool of resources, metered by use. Due to mentioned benefits the concept of cloud computing fits very well with the concept of m-learning which differs from other forms of e-learning, covers a wide range of possibilities opened up by the convergence of new mobile technologies, wireless communication structure and distance learning development. The concept of cloud computing like any other concept has not only benefits but also introduces myriad of security issues, such as transparency between cloud user and provider, lack of standards, security concerns related to identity, Service Level Agreements (SLA) inadequacy etc. Security concerns raised in cloud computing because of breaking the boundaries i.e. moving IT infrastructure from the organization´s firewall to Cloud Service Provider´s (CSP) firewall and relying on third parties for own data. This paper provides architecture of a collaborative m-learning by using cloud server and discusses the issue by introducing user centric identity management and enhanced auditing. The goal of this research is to provide more control over data to the cloud user, which is now controlled by CSP.
