A New Identity-based Designated Verifier Signature Scheme Using Bilinear Pairings
Zhao Yong-cha · Jiangxi kexue · 2013
In general,a digital signature,any owner of the signature's public key can verify the validity of the signature. But this nature,in the case of the signer wants to protect their privacy,is undesirable for the person who sign this signature. The concept of Designated Verifier Signature can solve this case. On the public authority for the key distribution problem,the identity-based technologies,also to be a good solution. Using the bilinear identity-based cryptography can be achieved the application of signature. In this paper we base identity-based cryptography scheme and using the bilinear knowledge,referring to previous designated verifier signature scheme proposed this program. In the system sets stage add an one-way collision Hash function,select a parameter in the signature stage,and in signing and validation phase apply this set. And in the end we analyze this programs in verifiability,security and performance.
