HIGH CERTIFICATE AUTHORITY SCHEME FOR AUTHENTICATION IN MOBILE AD HOC NETWORKS

S.Geetha, Dr.R.Maruthamuthu



Mobile ad hoc networks (MANETs) are self-organizing networks of mobile nodes that communicate with each other without the need for a centralized infrastructure. This makes them attractive for a variety of applications, but it also introduces security challenges.This paper proposes a high certificate authority (CA) scheme for authentication in MANETs. The scheme uses a combination of trust-based packet forwarding and certificate revocation to provide a high level of security.The trust-based packet forwarding scheme uses the routing layer information to assign trust values to each node. These trust values are used to favor packet forwarding by maintaining a trust counter for each node. If the trust counter falls below a threshold, the corresponding intermediate node is marked as malicious.The certificate revocation scheme uses the Shamir's secret sharing scheme and modified Shamir secret scheme to provide a secure and flexible way to revoke certificates.The proposed scheme has been evaluated using simulations, and the results show that it achieves a high packet delivery ratio while maintaining low delay and overhead.
