The Context Awareness Architecture in Mobile Cloud Computing

With the rapid development of mobile cloud computing, the identity authentication has become more and more important. but most of the authentication methods were authenticating device rather than users. Context aware information, such as, operational context, personal context, spatial context, and environmental context, can provide users with their really needed services without any explicit requests. a CAA based on context computing is proposed in this paper to mobile cloud computing environment and establishing relevant architecture to support, users will use the mobile cloud computing safer and more convenient.
