Authentication Protocols for WSN using ECC and Hidden Generator

Authentication is an important Security primitive in any class of network both at the entity level as well as at the message level. All the network entities comprising of WSN including nodes, cluster heads and base station need to be authenticated before sending or receiving any kind of communication within them. Public Key Cryptography offers broad based solutions to address all the security concerns. However such solutions are far too expensive to be applied directly to WSN owing to its resource constraints. ECC and its variant TinyECC offers the scope and the potential to build light weight solutions for WSN based networks.
