本文证明了基于身份的加密方案()的标准安全概念，即IND-ID-CCA2，抓住了所有方案的安全本质。为了达到这一目的，我们首先描述了安全概念的形式化定义，然后给出了OW、IND、SS和NMin之间的关系，并给出了严格的证明。从全面性的角度出发，提出了多消息加密环境下和/或多个接收者的安全概念。所有这些结果都是在考虑文[1]中的特定攻击，即自适应选择身份攻击的情况下提出的。
This paper shows that the standard security notion for identity based encryption schemes (), that isIND-ID-CCA2, captures the essence of security for allschemes. To achieve this intention, we first describe formal definitions of the notions of security for, and then present the relations amongOW, IND, SSandNMin, along with rigorous proofs. With the aim of comprehensiveness, notions of security forin the context of encryption of multiple messages and/or to multiple receivers are finally presented. All of these results are proposed with the consideration of the particular attack in, namely theadaptive chosen identity attack.
