Abstract: Many applications employ Wireless Sensor Networks (WSN) like tracking, controlling, monitoring and transferring. One of the important features of WSN is security. However, in WSN the solutions of security are different from traditional networks due to limited resources and computational constraints. As long as computer techniques are rapidly evolving, security protocols implemented over time can be broken. Keeping secrecy in WSN’s data transmission is a big challenge since this type of wireless networks allows remote data transfer. Cryptography is the security solution of most WSN applications. Recently, asymmetric and symmetric algorithms have been widely used in WSN systems with low computational energy power. This study suggests building a hybrid security protocol of two low power encryption algorithms which are asymmetric Elliptic Curve Cryptography (ECC) algorithm with Advanced Encryption Standard (AES) symmetric algorithm. Different key seeds are generated using a proposed combination of multiple ECC algorithms with a hash function. The resulted keys are used to encrypt the secret data using an AES algorithm in WSN communication. Randomized results of the proposed protocol are tested using the Diehard test. The proposed system has high randomness (more security) than other hybrid systems of previous researches.
