Comparative Analysis of Methods for Distribution of Certificate Revocation Information in Mobile Environment

Mobile Systems have been emerged as a means to provide a new stream of data related services such as wireless internet, video calling, and mobile commerce activities. Now a days, public key infrastructure (PKI) has been evolved into wireless PKI to secure these data related services in wireless scenario. PKI involves application of public key cryptography while generating the digital certificates in a secured manner. The validation of these certificates guarantees secured usage of digital certificates. Various schemes have been reported in the literature for certificate validation, for example Certificate Revocation List. These certificate validation schemes may be described on the bases of distributing certificate status information. The two prominent mechanisms for distributing certificate status information are push and pull mechanism. In this paper, we study two method as Certificate Revocation List Distribution Service (CRL-DS) and Super Peer method for distributing CRL through the push and pull mechanism respectively. The paper analyses these two methods from the wireless perspective.
