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...
We exhibit an attack against a signature scheme recently proposed by Gennaro, Halevi and Rabin [9]. The scheme's security is based on two assumptions namely the strong RSA ass...
In order to reduce key sizes and bandwidth, several LFSRbased (linear feedback shift register) public key cryptosystems and signature schemes have been proposed. Digital signature...
The concept of universal designated verifier signatures was introduced by Steinfeld, Bull, Wang and Pieprzyk at Asiacrypt 2003. These signatures can be used as standard publicly ve...
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
