For the two last decades, electronic authentication has been an important topic. The first applications were digital signatures to mimic handwritten signatures for digital document...
Harn et al. proposed a series of Diffie-Hellman key exchange protocols which are integrated into Digital Signature Algorithm in 2004. Recently, Phan pointed out that Harn et al....
An aggregate signature scheme is a digital signature scheme where anyone given n signatures on n messages from n users can aggregate all these signatures into a single short signa...
Nguyen and Shparlinski recently presented a polynomial-time algorithm that provably recovers the signer's secret DSA key when a few bits of the random nonces k (used at each s...
We present a polynomial-time algorithm that provably recovers the signer's secret DSA key when a few bits of the random nonces k (used at each signature generation) are known ...
