We present Badger, a new fast and provably secure MAC based on universal hashing. In the construction, a modified tree hash that is more efficient than standard tree hashing is us...
The security of hash functions based on a block cipher with a block length of m bits and a key length of k bits, where k ≤ m, is considered. New attacks are presented on a large ...
One-way hash functions are an important tool in achieving authentication and data integrity. The aim of this paper is to propose a novel one-way hash function based on cellular aut...
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. We present a related family of authentication and digital signature protocols based on symmetric cryptographic primitives which perform substantially better than previous...
