A Framework of Deployment Strategy for Hierarchical WSN Security Management
نویسندگان
چکیده
The heterogeneity and relative limited resources of the nodes deployed in hierarchical wireless sensor network (WSN) impose a new strategy to guarantee security and confidentiality. A deployment strategy is proposed and focuses on two different levels: complexity of the scheme and security requirement for the application. Three different cryptography mechanisms may be concurrently used in the same framework: PKI distribution, identity-based encryption and symmetric cryptography. As each mechanism highlights drawbacks and advantages, criteria are proposed to associate each node with the most relevant security mechanism according to its capability and environment.

The proposed framework applies two game theoretic models for economic deployment of intrusion detection system (IDS). The first scheme models and analyzes the interaction behaviors of between an attacker and intrusion detection agent within a non-cooperative game, and then the security risk value is derived from the mixed strategy Nash equilibrium. The second scheme uses the security risk value...
