Abstract— Encryption of information is acrucial achievement for VANET in order to reduce accidents & consequentlyimproves traffic conditions to save lives. Security comes to informationonly when we provide encryption to information. Wireless communication isubiquitous because of its flexibility to adapt to different scenarios. Soauthentication concept allows trusting both user and information, therefore, inorder to increase the feasibility and better performance of cryptographic basedprotocols, we should have to investigate operationof different cryptography based methods.
Keywords: - VANETs, Encryption, Decryption, NIST, RSA,and Hash function.
