Cryptanalysis of ID-Based Authenticated Key Agreement Protocols from Bilinear Pairings (Short Paper)

摘要

Recently, a number of ID-based authenticated key agreement protocols from bilinear pairings have been proposed. In this paper we present security analysis of four ID-based authenticated key agreement protocols from pairings proposed in [11, 12, 7, 18]. These results demonstrate that no more ID-based authenticated key agreement protocols should be constructed with such ad-hoc methods, I.e, the formal design methodology as in [1, 2, 3, 10] should be employed in future design.
