摘要：Security impact on mobile ad hoc network increases more since there is no architecture and high mobility of nodes along the environment. Security features include providing authentication and confidentiality. Both these services insist that the messages should be encrypted and decrypted using some keys either public key and private key. Before encrypting the information to be secure, the users in the network should authenticate themselves since there is a central point to control the users. In this paper, we have taken our VBSR protocol for the implementation of authentication mechanism. In this work, a hash value is found then it is checked at receiver for authentication that the message is generated by the authorized sender and a secure protocol is developed called Hashed VBSR (HVBSR). The hash value �H� is found using the hash function since the hash function can be taken as a way to compute the Message Authentication Code (MAC). Since the high dense of mobile nodes cannot be provide best security, the mobile nodes must be formed as groups. In order to provide security, there are pre-requirements like public key infrastructure (PKI), group key management and key agreement and key agreement so on. Then these keys are used in the encryption/decryption algorithms such as symmetric key algorithms and asymmetric key algorithms.
