在随机谕示模型下,研究一类基于身份的签名体制(称为基于身份的一般签名体制)的安全性.所得理论成果可以被看作Pointcheval和Stern提出的Forking引理在基于身份签名体制研究领域的扩展,有助于理解和简化一些现有的基于身份签名体制的安全性证明,如Cha-Cheon的体制、Hess的体制1及Cheon-Kim-Yoon的体制等.
Under the random oracle model, we study the security of a type of identity-based signature system (called the identity-based general signature scheme) .The resulting theoretical results can be viewed as Forking Lemmas by Pointcheval and Stern in the Identity-Based Signature System The expansion of the domain helps to understand and simplify some of the existing evidence of identity-based security systems such as Cha-Cheon’s system, Hess’s system1 and Cheon-Kim-Yoon’s system.
