Secure Verifiable Active Access Control for Medical Sensor Networks

Active access control is important yet difficult to implement in Medical sensor networks (MSNs). In this paper, a Secure verifiable active access control (SVAAC) scheme is proposed to enhance activeness and security of access control for MSNs. In the SVAAC scheme, based on event triggeration mechanism, access control policies can change adaptively, and active authorization and access control can be guaranteed??and the confidentiality and integrity of authorizations are also ensured.
