Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on "fingerprinti...
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...
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...
Dispute of transactions is a common problem that could jeopardise business. Hence non-repudiation services are essential in business transactions which provide evidence to enable ...
