We formalize the problem of analog data compression and analyze the existence of a polynomial data compression function. Under relaxed conditions we explore the existence of a sol...
TTS is a genre of multivariate digital signature schemes first proposed in 2002. Its public map is composed of two affine maps sandwiching a Tame Map, which is a map invertible t...
Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on "fingerprinti...
Abstract. ISO 9796-1, published in 1991, was the first standard specifying a digital signature scheme with message recovery. In [4], Coron, Naccache and Stern described an attack o...
Authentication of digital documents is an important concern as digital documents are replacing the traditional paper-based documents for official and legal purposes. This is espec...
