The security of hash functions has recently become one of the hottest topics in the design and analysis of cryptographic primitives. Since almost all the hash functions used today ...
Abstract. In the context of iterated hash functions, "dithering" designates the technique of adding an iteration-dependent input to the compression function in order to d...
Encrypt-and-sign, where one encrypts and signs a message in parallel, is usually not recommended for confidential message transmission. The reason is that the signature typically l...
