Colliding X.509 Certificates

Arjen Lenstra, Xiaoyun Wang, and Benne de Weger

Abstract

We announce the construction of a pair of valid X.509 certificates with identical signatures.

Note: This announcement now appears (slightly rewritten) in an appendix to the full version of the paper "On the possibility of constructing meaningful hash collisions for public keys" by Arjen Lenstra and Benne de Weger. This paper will be presented at ACISP 2005, Brisbane, July 4-6. Due to page limitations the appendix could not be incorporated in the "proceedings version" of the paper. The appendix appears only in the "full version" of the paper, which can be downloaded from http://www.win.tue.nl/~bdeweger/CollidingCertificates/.
