An Efficient Pairwise Key Predistribution Scheme for Wireless Sensor Networks
Key management plays fundamental role in research on security service in wireless sensor networks (WSNs). However, due to the resource constraints, establishing pairwise keys in WSNs is not a trivial tasks. Several exiting key management schemes have been proposed in literature to establish pairwise keys between sensor nodes, but they either can not offer strong resilience against node capture ...
متن کاملKey Predistribution Scheme for Wireless Sensor Networks with Higher Connectivity
In wireless sensor network (WSN), preditibution of cryptographic keys is possibly the most practical approach to perfect network communications. In this paper, we propose a new secret key predistribution scheme to achieve a higher connectivity in WSN. For this we combine a random key predistribution scheme and hash chain method based on the prior knowledge of sensor node deployment. The propose...
متن کاملTwo Improvements of Random Key Predistribution for Wireless Sensor Networks
Key distribution is of a critical importance to security of wireless sensor networks (WSNs). Random key predistribution is an acknowledged approach to the key distribution problem. In this paper, we propose and analyze two novel improvements that enhance security provided by the random key predistribution schemes. The first improvement exploits limited length collisions in secure hash functions...
متن کاملHierarchical Grid-Based Pairwise Key Predistribution Scheme for Wireless Sensor Networks
Wireless Sensor Network (WSN) consists of huge number of sensor nodes which are small and inexpensive with very limited resources. The public key cryptography is undesirable to be used in WSN because of the limitations of the resources. A key management and predistribution techniques are required to apply the symmetric key cryptography in such a big network. Many key predistribution techniques ...
متن کاملA Robust Pairwise Key Predistribution Scheme Resistant to Common Attacks for Wireless Sensor Networks
Security is very necessary for secure operations in wireless sensor networks (WSNs), especially in hostile environments. To achieve security, key agreement needs to be implemented efficiently among communicating nodes. Nonetheless, acquiring such key agreement in WSNs becomes extremely intricate due to resource constraints. Among approaches so far, key predistribution approach is considered as ...
