Provable Data Possession (PDP) schemes which are vital to data-oriented mobile cloud computing security architecture enable users to check the integrity of their data in the cloud efficiently. Due to the limitation of storage space and computing power of the mobile terminals, a new identity-based proxy signature multiple-file data integrity verification scheme called Identity-Based Proxy Signature...
This paper analyzed the shortages of S/KEY OTP system in mobile commerce identity authentication and suggested an improved one-time password system based on bidirectional virtual authorization in mobile application systems. On one hand, this suggestion can reduce the calculation stress of both client and server, accordingly increases the efficiency of authorization and withstands the DoS attack. On...
Two-dimensional code has been widely used in mobile commerce. With the information contained in the code, a purchase always happened. For mobile user, the convenience and security is important. This paper analyzed the shortages of S/KEY OTP system in mobile commerce identity authentication and suggested an improved one-time password system based on bidirectional virtual authorization in mobile application...
Mobile Grid is one of the recent emerging technologies. It has a lot of challenges due to the scarcity of resources such as processing power, persistent storage, runtime heap, battery lifetime, memory, bandwidth, and connectivity and network faults. Dynamic environment affects both mobile and non-mobile grids. This creates a need for the virtual administrator. Virtual Organization (VO) is responsible...
