Signcryption
In cryptography, signcryption is a public-key primitive that simultaneously performs the functions of both digital signature and encryption.Encryption and digital signature are two fundamental cryptographic tools that can guarantee the confidentiality, integrity, and non-repudiation...
cryptographic primitive that combines the digital signature and encryption operations into one single step. He also invented the HAVAL
HAVAL
HAVAL is a cryptographic hash function. Unlike MD5, but like most modern cryptographic hash functions, HAVAL can produce hashes of different lengths. HAVAL can produce hashes in lengths of 128 bits, 160 bits, 192 bits, 224 bits, and 256 bits...
