摘要
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.
This paper offers arguments for the provable security of a class of ID-based signature schemes called ID-based generic signature schemes in the random oracle model. The theoretical result can be viewed as an extension of the Forking Lemma due to Pointcheval and Stern for ID-based signature schemes, and can help to understand and simplify the security proofs of previous work such as Cha-Cheon's scheme, Hess's scheme-l, Cheon-Kim-Yoon's scheme, and so on.
