Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived 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...
In a blind signature scheme, the user can get a signature sig(m) on message m generated from the signer's blind signature sig(m ) on blinded message m , but the signer can...
We propose a low complexity analog joint source channel coding Multiple Description (MD) scheme for transmitting the symbols of a Gaussian source across a pair of independent AWGN...

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...
