This definition hence comprises notions and constructions for concrete predicates . such as homomorphic signatures and redactable signatures..In our work w

BLAKE2 comes in two main flavors: BLAKE2b is optimized for 64-bit platforms, and BLAKE2s for smaller architectures. On 64-bit platforms, BLAKE2 is often faster than MD5, yet provides security similar to that of SHA-3: up to 256-bit collisio

Therefore it is interesting both from a theoretical and from a practical point of view, to get precise security results for this construction. In this paper, we will describe the best attacks that we have found

The first target is a standard Feistel network with an SP round function. Up to 11 rounds can be attacked in generic if a condition on a key sch
