Cryptanalysis of White-Box DES Implementations with Arbitrary External Encodings
Abstract. At DRM 2002, Chow et al. [4] presented a method for implementing the DES block cipher such that it becomes hard to extract the embedded secret key in a white-box attack c...

Collisions for 70-Step SHA-1: On the Full Cost of Collision Search
The diversity of methods for fast collision search in SHA-1 and similar hash functions makes a comparison of them difficult. The literature is at times very vague on this issue, wh...

Existence of Modular Sonar Sequences of Twin-Prime Product Length
In this paper, we investigate the existence of modular sonar sequences of length v and mod v where v is a product of twin primes. For v = 3 · 5 = 15, we have found some old and ne...

On the Necessity of Rewinding in Secure Multiparty Computation
We investigate whether security of multiparty computation in the information-theoretic setting implies their security under concurrent composition. We show that security in the sta...
