摘要：Mobile Ad-hoc Networks (MANET) is a network consisting of a collection of nodes which cancommunicate with each other without help from a network infrastructure. There has been a growing interest in MobileAd hoc Networks (MANETs) motivated by the advances in wireless technology and the range of potential applicationsthat might be realized with such technology. Due to the lack of an infrastructure and their dynamic nature, MANETsdemand a new set of networking protocols to harness the full benefits of the versatile communication systems. TheCipher Block Chaining (CBC-X) mode is used to complete message authentication, encryption and decryptionconcurrently before sending message.In order to provide the data integrity, an enhanced distributed certificate authority scheme (EDCA) isdeveloped. This scheme makes the network more secure from both inside and outside attacks. It utilizes threecomponents namely monitoring Routing Cum Forwarding (RCF), certificate revival and certificate revocation.RCFinvolves detectingmisbehaviors in both the routing as well asthe packet forwarding in the network. Certificate revocation provides the authority to isolate the malicious nodes orregain the nodes which turn up to its best state after any attack or failure. Certificate revival scheme is used forincreasing the data integrity of the packets. In this revival scheme, every legitimate node carries a certificate which isissued by certificate authority to make the communication between the nodes inside the network. For providingcertificate authority, the Shamir’s secret sharing scheme and modified Shamir secret scheme are used.It provides security as well as is extendable and flexible. Based on the results, it is observed that the enhanceddistributed certificate authority scheme achieves more packet delivery ratio while attaining less delay and overheadthan the trust based cross layer security protocol.
