Dissemination is a service provided for WSN to update the deployed sensor nodes online by using over air programming through radio communication. Since centralized data dissemination approach suffers from the limitations of single point of failure lack of scalability and security they have been replaced by distributed approach. In distributed data dissemination, the dissemination privileges are delegated by the network owners to the network users to disseminate the data items on their behalf. In distributed environment network owner and network users are two different types of entities. In an effective and secure data dissemination system a Network user needs to maintain his/her privacy from the network owner and network owners need to track and pinpoint the misbehaved network user. So it is required to provide the privacy to the network users, provide varying access control privileges according to the nature of network user and ensure accountability for every action carried out by network users In this paper we propose novel (PEAC) Privacy enhanced Access Control key management algorithm that enforces privacy and access control among the network owners and network users. It also provides the accountability by tracing the network owner to pinpoint the misbehaved network user. The feasibility and efficiency of PEAC scheme has been done by performing the in depth analysis to identify its possible strength and weakness.
