A Secure Electronic Student Record using Hierarchal Identity-based Authentication over University Cloud Storage

Cloud computing is a state-of-the-art technology to build a storage platform for data backup, resource sharing, file synchronization, etc. there for modern university environments, university providers are more willing to move their electronic student record systems to cloud. This archetype enable to achieve better interoperability and lower operational cost with other university providers, instead of building and maintaining dedicated data centers. However, many security challenges associated with authentication, identity management, access control, trust management, and so on, may raise in the adaptation of cloud computing in electronic student records (ESR) systems. To satisfy these requirements, we present the hierarchy feature of the hierarchical identity based authentication (HIBA) and key agreement to propose a systematic access control mechanism to support sharing data of (ESR) aggregated from various university providers in clouds as an application. The feasibility and efficiency of our approach demonstrate by implementing a concept prototype along with security evaluation.
