Key Management is a major challenge to achieve security in wireless sensor networks. To solve the problem of the limit storage space and resilience against node capture in random key management scheme for WSN, a new key management is proposed, which is based on ECC (Elliptic Curve Cryptography). The design mainly contains the key pre-distribution based on ECDSA, key agreement based on shortest-path-tree...
Key management is a major challenge to achieve security in wireless sensor networks. Previous research on sensor network security mainly considers homogeneous sensor networks, where all sensor nodes have the same capabilities. The recent research has shown that the survivability of the homogeneous sensor network can be improved if sensor nodes are grouped in clusters in which a powerful cluster head...
