Enhancing the security in signature verification for WSN with cryptographic algorithm

Security plays an vital role in wireless sensor networks. Since the nodes are deployed in the physical environment, Hackers may easily access the data. In order to provide security, The Advanced Encryption Standard (AES) algorithm has developed into an option for various security services. Non-Linear arrangements or mechanism of S-Box and RCON of this implementation algorithm is to provide a physically powerful cryptography technology in wireless sensor networks. Initially generate the private and public key for each user and signature verification can be done. This non-linearity provides high degree of security while transmitting data in the wireless sensor networks.
