Comparison of RSA and ECC Public key Cryptography Techniques in WSN

Abstract

Nowadays, the usage of the wireless sensor networks becomes more advanced and popular. The more these technologies are increasing; there is more necessity for the security mechanisms where the networks have increased diverse. So many security mechanisms solutions are been proposed in the domain of WSN so far and mostly these solutions are usually based on the cryptographic techniques or algorithms. This paper describes two public key cryptography techniques namely, RSA and elliptic curve cryptography (ECC), and consider the mutual authentication and key exchange between two untrusted parties such as two nodes in a wireless sensor network. In other words, the digital signature standard and its verification of the message is generated in both the public key algorithms. Additionally, the Diffie hellman and Elgamal algorithms are also be calculated to provide the keys of the user securely. It is seen that ECC has more advantages and powerful compared with RSA in terms of key exchange, mutual authentication.
