A User Identity Management Protocol Using Efficient Dynamic Credentials

Today mobile devices make use of the services provided by the newly emerging technology Mobile Cloud Computing(MCC) to overcome the challenges of resource limitations such as, battery life, storage, computation power and bandwidth. Though this new technology is very flexible to use but however, the mobile devices are facing many challenges related to security. The legitimate users prove their identity to cloud using digital credentials such as passwords and digital certificate. As the technology has become very transparent adversaries may hack the valuable credentials of the user without the knowledge of legitimate user. The attackers may draw the services from cloud using the users credentials and fool the cloud. The users will not come to know of this theft until some disaster has been done by the hacker. This system model proposes an light weight algorithm which reduces the burden of processing on mobile device as all computation are carried on trusted entity and it also improves the security of users Credentials by updating it dynamically based on the user and cloud communication
