Security is an encapsulated concept includes authenticity of user, integrity and confidentiality of data during transmission. In wireless communication there are more threats for breach the security due to the openness of wireless network and no boundary limitations. It is free for access and anyone can easily access the network or steel the identity of other to access the network in the absence of proper security mechanisms. Proof of user identity on network is just like challenge for current scenario. Node verification is the vital procedure for wireless communication. The authors proposed a verification technique that use hash code for verification and also proposed 2D cryptography technique to maintain data integrity and confidentiality during transmission.
