Temkin1, A., Boyer1, J., Brown1, K., Ramesh1,2, M., and Wu1,2., C.

In the Proceedings of 10th Annual International Conference on Computer Science and Education in Computer Science, Albena, Bulgaria, (July 2014).

In this paper, we extend the work of Stevens, et al. [Stevens 2007] to produce a pair of PDF documents that not only hash to the same value under MD5, but also contain a valid PDF signature block.
