Certificate Chain based Authentication in MANETs Using 4th Generation Technologies
[attachment=51305]
ABSTRACT
Mobile Ad-hoc Networks (MANET) are the infrastructure-less networks comprising mobile nodes. The nodes can move and change their location in networks. The mobile nodes have two roles to perform simultaneously in MANET i.e. it communicates with other nodes and route the received packets to the destination nodes.
MANET security is becoming interesting because of its infrastructure-less networks gives rise to authentication and key-management problems in the MANETs. Authentication of an entity is the hallmark of security, is acting as a key block in the way of enhancing the MANET security. Here, nodes can enter or exit in a randomly manner, that leaves the MANET exposed to attack.
Most of the Trusted Third party (TTP) and non-TTP based schemes seem to be infeasible for being adopted in MANETs. A hybrid scheme can server the purpose. One of the hybrid schemes addressed these issues effectively by pre-assigned logins on offline basis and issuing certificates on its basis using 4th generation services.
In this proposed model, we have tried to remove the drawbacks in two existing key management schemes by merging them in a way that the new scheme overcomes their inefficiencies regarding overheads and security.
