Digital Signature Algorithm (DSA) is an underlying algorithm to form a signature in the Digital Signature Standard (DSS). DSA uses a new random number (or nonce) each time a signa...
An important feature of digital signatures is to serve as nonrepudiation evidence. To be eligible as non-repudiation evidence, a digital signature on an electronic document should...
Undeniable signatures were proposed to limit the public verification property of ordinary digital signature. In fact, the verification of such signatures cannot be obtained withou...
This paper investigates some modular powering functions suitable for cryptography. It is well known that the Rabin encryption function is a 4-to-1 mapping and breaking its one-wayn...
We present the hash-based signature scheme XMSS. It is the first provably (forward) secure and practical signature scheme with minimal security requirements: a pseudorandom and a ...
