Software as a Service (SaaS) provides a useful and convenient way for cloud users to enjoy cloud service, but security problems have caused great influence on the development and popularization of SaaS. As a commercial model, SaaS involves different roles of participants who could be dishonest and malicious. This paper presents a security protocol to address several security issues in SaaS and protect the rights and interests of all participants. Our design is based on identity-based proxy signatures from pairings. The analysis shows that the presented protocol can effectively strengthen the security of SaaS in cloud computing.
