Multiple-Differential Side-Channel Collision Attacks on AES
In this paper, two efficient multiple-differential methods to detect collisions in the presence of strong noise are proposed - binary and ternary voting. After collisions have been...

Improved Collision Search for SHA-0
At CRYPTO2005, Xiaoyun Wang, Hongbo Yu and Yiqun Lisa Yin proposed a collision attack on SHA-0 that could generate a collision with complexity 239 SHA-0 hash operations. Although t...

Finding SHA-1 Characteristics: General Results and Applications
The most efficient collision attacks on members of the SHA family presented so far all use complex characteristics which were manually constructed by Wang et al. In this report, we...

Interval methods for multi-point collisions between time-dependent curved surfaces
We present an efficient and robust algorithm for finding points of collision between time-dependent parametric and implicit surfaces. The algorithm detects simultaneous collisio...

A New Class of Collision Attacks and Its Application to DES
Until now in cryptography the term collision was mainly associated with the surjective mapping of different inputs to an equal output of a hash function. Previous collision attack...

Collision prediction for polyhedra under screw motions
The prediction of collisions amongst N rigid objects may be reduced to a series of computations of the time to first contact for all pairs of objects. Simple enclosing bounds and...

Cryptanalysis of the Hash Functions MD4 and RIPEMD
MD4 is a hash function developed by Rivest in 1990. It serves as the basis for most of the dedicated hash functions such as MD5, SHAx, RIPEMD, and HAVAL. In 1996, Dobbertin showed ...

Controlling the entire path of a virtual camera
This paper considers the design of a camera path through a scene. Given a valid set of keyframes for the camera, we want to build a camera path that avoids collisions with the sce...

Collision Model for Bit Error Rate analysis of Time Hopping Impulse Radio in Multipath Nakagami-m Channels
— In presence of multiple access interference, the performance of impulse radio system is affected by collisions with other users. In this paper we evaluate the bit error probabi...
