Secure and efficient key management scheme for wireless sensor networks

Abstract

Taking into account the current developments and increased application of wireless sensor networks, it has become increasingly important to pay greater attention to the security of wireless sensor networks which are more prone to threats as compared to the wired networks. We have proposed a highly secure and efficient scheme for wireless sensor networks. We have designed a key management technique to ensure maximum security of the wireless sensor network and also of every individual node subject to various hostile environments and situations. This scheme ensures that compromised sensor nodes are resilient towards attack before and after mutual pairwise path establishment. It is a self enforcing scheme and analysis shows that it is more resilient to sensor capture attacks than the previous schemes.
