Abstract

One-pass authenticated key establishment (AKE) protocols are arguably better suited to the ID-based environment than their two-pass counterparts. However, there is no ID-based one-pass AKE protocol proposed in the literature with a proof of security in an appropriate model. This paper addresses the current gap by proposing a new ID-based one-pass AKE protocol and proving it secure in a formal model. The security of the new protocol is treated under a model adapted from a formal security model for traditional certificate based AKE protocols. The proof of security is in the random oracle model and is based on the hardness of the bilinear Diffie-Hellman problem. The protocol also turns out to be the most efficient of all the previously known protocols. It can work over a class of asymmetric pairings for better efficiency at higher bit security levels.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
