Abstract:The advancements in smartphones with excellent feasibility and networking capabilities paved the way for rising leap in mobile communication, but their limitations incline users to next level paradigm called Mobile Cloud Computing. Despite the cloud services reaching far greater heights, the issues of to security and privacy needs to be addressed. Therefore, our proposed Client Aware Certification (CAC) model ensures to identify the authenticity of client devices connected to the cloud based on the behaviour predictability and security checks. A resource broker identifies the trustworthiness of the client devices before offloading any task. Integrity check, privacy protection, and access patterns are some of the attributes considered for offloading decision. The model achieves better security, privacy, and performance for resource migration. Identity management and certification feature ensure a better predictability with secure virtual communication. The model is experimented with AWS cloud platform and tested for a video conversion application.
