Key management is a corner stone service for any security solution for WSNs. Resources limitation of WSNs makes the public key based solutions, which offer more efficient key management services, unsuitable for wireless sensor networks. In this paper, we propose a novel efficient tree-based probabilistic key management scheme which is highly resilient against node capture attacks. Our solution is...
Wireless sensor networks (WSN) have received a lot of attention recently due to their wide range of applications in military as well as civilian operations. It is a challenging work to design suitable cryptography for wireless sensor networks since the limitations of power, computation capability, and storage resources. Many schemes based on symmetric or public key cryptography have been investigated...
In order to solve the problems that sensor node-key leaking and adversaries make compromised nodes as their collusions to launch new attack, the paper proposed an efficient anti-collusion scheme based on elliptic curve cryptography for wireless sensor networks. In the proposed scheme, the group-key distribution strategy is employed to compute the private key of each sensor node, and the encryption...
