摘要：Wireless Network has been gaining rapid popularity over the years because they provide a significant advantage over the traditional Wired Network. Many wireless networks are based on security scheme Wired Equivalent Privacy (WEP). Despite employing the well-known and believed-secure RC4 cipher, WEP falls short in accomplishing its security goals. In this paper weaknesses and possible attacks on the RC4 stream cipher in WEP have analyzed and we proposes more secure WEP Protocol that offers secure encrypted communication by using Elliptic Curve Cryptography (ECC) Technique. Point Multiplication is the core operation performed in ECC. NAF (Non – Adjacent Form) is the efficient method used for Point Multiplication. We implemented both Standard and Block method for computing NAF of ECC and done the comparative study of these methods by taking several parameters in WEP. The proposed ECC Technique will ensure secure encryption in WEP and will enhance its security.
