Identification and Avoidance of Malicious Nodes by using Certificate Revocation Method

Instant certificate revocation and publication using WebDAV

There are several problems associated with the current ways that certificates are published and revoked. This paper discusses these problems, and then proposes a solution based on the use of WebDAV, an enhancement to the HTTP protocol. The proposed solution provides instant certificate revocation, minimizes the processing costs of the certificate issuer and relying party, and eases the administ...

Certificate Revocation Using Fine Grained Certificate Space Partitioning

A new certificate revocation system is presented. The basic idea is to divide the certificate space into several partitions, the number of partitions being dependent on the PKI environment. Each partition contains the status of a set of certificates. A partition may either expire or be renewed at the end of a time slot. This is done efficiently using hash chains. We evaluate the performance of ...

Efficient Certificate Revocation of Attacker nodes using CCRVC in Mobile Ad Hoc Networks

Mobile Ad Hoc Networks (MANETs) is a selfconfiguring, infrastructure less network of mobile devices connected by wireless. The wireless and dynamic nature of MANET leads to various types of security attacks. The primary task is to provide the secure communication. To come across this challenge, we propose Cluster based Certificate Revocation with Vindication Capability scheme for certificate re...

Windowed Certificate Revocation

The advent of electronic commerce and personal communications on the Internet heightens concerns over the lack of privacy and security. Network services providing a wide range of security related guarantees are increasingly based on public key certificates. A fundamental problem inhibiting the wide acceptance of existing certificate distribution services is the lack of a scalable certificate re...
