一种无状态的传感器网络密钥预分配方案
A Stateless Key Pre-distribution Scheme for Wireless Sensor Networks
摘要
Abstract
Since the secret information such as the group key in the compromised sensor nodes in the wireless sensor networks (WSN) may be compromised by the adversary,it is necessary to build a secure and efficient group key management system to revoke the compromised sensor nodes.Based on the logical key tree,a key predistribution scheme is proposed.Each internal vertex of the logical key tree is assigned a set of keys. Each sensor node is assigned to a leaf of the logical key bee, and keeps the key sets assigned to the vertices on the path from the leaf to the root. During the revocation phase, the logical key tree is divided into disjointed subtrees. All the sensor nodes in the same subtree share a common key, which is used to encrypt the new session key. Analysis shows that the proposed scheme satisfies the stateless,correctness,group key secrecy,forward secrecy and backward secrecy.The performance analysis shows that the proposed scheme has a low storage,communication and computation overload,and it is applicable to WSN.关键词
