One of the main goals of Wireless Sensor Network (WSN) is to carry reliable information from one node to another node in a network. This paper is aimed in providing high security to wireless sensor networks using an improved AES-ECC hybrid encryption scheme. The paper analyses the AES algorithm and S-box structure, S-box structure is proposed to improve AES encryption algorithm. Using AES algorithm, Plain text message sent by sender is changed into completely new cipher text, looking into which attacker cannot guess original message at receiver using AES decryption, same plain text is successfully recovered from AES encrypted cipher text.
