摘要

在现实生活中,人们需要满足某些条件的人签名,比如他们应该拥有一些特定的属性。例如,Alice想要一份由Bob公司员工签名的文件。该员工必须具有某些属性,例如是IT人员的一部分,并且至少是密码学团队的初级经理或生物识别团队的高级经理。为了满足这些需求,我们定义了一种通用的基于属性的签名方案,其中签名成员必须具有特定的属性或属于特定的组,并证明了我们的方案是安全的。

Attribute-based Signature Scheme
In real life, one requires signatures from people who satisfy certain criteria like that they should possess some specific attributes. For example, Alice wants a document to be signed by some employee in Bob's company. This employee must have certain attributes such as being part of the IT staff and at least a junior manager in the cryptography team or a senior manager in the biometrics team. In order to satisfy these kinds of needs, we defined a common attribute-based signature scheme where the signing member has to have certain attributes or belong to a certain group, and we also proved our scheme to be secure.
