Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...
We consider a problem which was stated in a request for comments made by NIST in the FIPS97 document. The question is the following: Can we have a digital signature public key infr...
A new method is proposed to design short signature schemes based on difficulty of factorizing a composite number n = qr, where q and r are two large primes. Using the method new d...
Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on "fingerprinti...
We describe and analyze a new digital signature scheme. The new scheme is quite efficient, does not require the the signer to maintain any state, and can be proven secure against ...
