We give two attack strategies for searching collisions in sponge-based hash functions. Following one strategy, we give two non-practical collision attacks: a 6-round collision attack on Gimli-Hash with time complexity 2 and a 2-round collision attack on Ascon-Hash with time complexity 2. ...

One method of breaking a cipher is through cryptanalysis; finding a weakness in the cipher that can be exploited with a complexity less thanbrute force. The SHA-1 collision attack requires significant computational resources, but it is still 100,000 times faster than a brute-force effo...
The AES-GCM algorithm is one of the foundation algorithms in data security, therefore such data-pattern driven attack can potentially compromise the security of Big Data application. We present an attack model and an implementation of the attack based on OpenSSL, a widely used library that ...
Meet-in-the-middle attacksIn a meet-in-the-middle attack, Group A is typically some pre-calculated set of encrypted blocks, and Group B is a set of "real" encrypted blocks. The idea is to use the pre-calculated set of blocks to try and find at least one "real" encrypted block ...
Another example, albeit a narrowly-focused one, is the hash collision attack. The hashes addressed here are the kind used in computer science to form the basics of data structures or otherwise non-cryptographic uses. (It’s still possible to misapply cryptographic hashes like SHA-1; check ...
