Key-Insulated Encryption Based Key Pre-distribution Scheme for WSN

摘要

In wireless sensor network (WSN) security is as important as performance and energy efficiency for many applications. Key pre-distribution is a good approach to solve the key agreement problem in the WSN. Based on the Key-Insulated Encryption, a new key pre-distribution scheme, KIE-WSN scheme, is proposed in this paper. The proposed scheme has two important security properties: semantically security and optimal KIE-(N-1, N) safety, which means that even if N-l nodes are compromised, there are no security threatens to the left network. Compared with the existed schemes, the proposed KIE-WSN scheme has better performance in the storage and communication cost.
