摘要：Cloud computing platforms are usually constructed as trusted virtual platforms based on trusted computing technologies. This is one of the most effective approaches to resolve cloud computing security problems. However, the protection of sensitive data in trusted virtual platforms is an important problem needed to be resolved. In this paper, we proposed a novel authorization protocol. The protocol assembled the functions of OIAP, OSAP and AACP protocols, and prevented all known attacks in existing authorization protocols. Moreover, it satisfied the property of exclusivity and was compatible with TCG TPM command formats. The protocol effectively protects the sensitive data from unauthorized accesses in trusted cloud computing platforms.
