Self-healing group key management scheme with revocation capability for wireless sensor networks
Jun Min Pan · Journal of Communications · 2009
A new group key management scheme against the unreliable wireless communication channel and unsafe environment was proposed for wireless sensor networks.In the proposed scheme,broadcast polynomial,which was generated over finite field F_q based on the secret sharing,was employed to revoke compromised sensor nodes.In order to tolerate key-update message loss and be self-healing,group session keys were generated as one-way hash chain sequence and distributed in advance.The analysis shows that our scheme has better performance in terms of the computation and communication overhead.
