ABSTRACT

Neal Koblitz and Victor Miller independently proposed elliptic curve cryptography (ECC). This is an efficient technique, which provides security for wireless communication. Earlier we were using wired equivalent privacy (WEP) protocol and Rivest-shamir-Adleman (RSA) scheme, which largely stimulated the research and development of security protocols for wireless communication. The efficient technique elliptic curve cryptography overcomes the disadvantages of WEP and RSA. Here we are proposing a mutually authenticated key agreement protocol that employs elliptic curve digital signature algorithm (ECDSA) exchange used for mutual authentication and key exchange respectively. The principal attraction of ECC, compared to RSA, is that it appears to offer equal security for a far smaller key size thereby reducing processing overhead. The proposed protocol can be implemented in both basic service set (BSS) and extended service set (ESS).
