Research On Attribute-based And Forward-secure Digital Signature

In the field of information security, digital signature is already one ofthe key technologies. Digital signature has been widely used, especially inlarge networks, e-commerce, e-government and other more fields. To getmore applications at the same time, the digital signature technology isconstantly adapted to the new application environment, to solve the newproblems in the process of continuous rapid development. In generaldigital signature technology development has two directions: the first is tosolve the digital signature safety problem; the second is addressed in thenew area or new application environment how to improve and design of anew digital signature scheme problem.This article first briefly introduced the basic knowledge and theoryneeded in the research of attribute-based and forward-security digitalsignature, and a brief review of the attribute-based cryptography andforward-security digital signature development situation.The next part introduced definition and security model of theattribute-based digital signature and the forward-security digital signature.In this part, several schemes are introduced and some analyses are gived.In this last of this part, the attribute-based and forward-secure digital signature scheme is proposed and gives the security proof of the scheme.Finally, this paper points out the development prospect and thepossible research direction of the attributes-based and forward-securitydigital signature.
