Survey on Identity-based Key Establishment Protocols for Wireless Sensor Networks
Chunguang Ma · 2010
Wireless sensor networks(WSN)security faces more challenges than traditional Ad hoc networks due to its highly self-organization and limited energy.Key management is one of the fundamental security issues in WSN.As a vital part of key management,session key establishment needs to achieve a trade-off between security and performance.In this paper,a survey on Identity-based key establishment in WSN was provided.We firstly described the identedity-based cryptography from its three fundamental primitives,then presented some security properties and security models ofidentity-based key agreement protocols,analyzed the existing identity-based key establishment protocols for WSN to point out their shortages,and finally discusses the research area of Identity-based key establishment for WSN in the future.
