The application and deployment of wireless Ad hoc networks provided great conveniences for people. Meanwhile, it also brought great challenges. One of the most important issues is privacy preservation, especially the protection of user’s sensitive information in the process of access control. This paper puts forward the idea of multi-factor authentication, and designs an access control scheme that supports privacy preservation and network service optimization. This scheme realizes the aim for protecting users’ sensitive information by adopting the improved ring signature technology, and achieves the goal of fine-grained access control through relevant calculations of the user attribute set. In addition, a new definition of access control is proposed for the first time, and the incentive mechanism is added to the scheme, which can promote network nodes to provide resources with high quality and to optimize network service.
