Secure Data Transmission Based on Elliptic Curve Cryptography for WSN

Abstract

In recent years, wireless sensor networks have become very widespread. They're usually deployed in hostile areas, making it easier for the hacker and make them vulnerable to several attacks in which the intruder can take control of one or more nodes to disrupt the proper functioning of the network.Recently, a mutual authentication and key management scheme was proposed to secure data transmission in WSNs. In this research work, we show that this scheme has various security flaws, such as MITM attack and lack of mutual authentication between sensor nodes. Then, we propose an enhanced scheme to overcome the identified security weaknesses. Our scheme is implemented using the cryptographic library RELIC and ECMQV scheme. After a set of tests on cooja simulator, the results obtained showed that our proposal achieves good performances in terms of energy consumption, computational and communication costs. In addition, our scheme guaranties a good level of security compared to SDTS.
