Abstract: A definition of universally composable security of identity-based signature schemes is proposed in the universally composable security framework. The equivalence of the universally composable security and the traditional security of identity-based signature schemes is proved. This result shows that an identity-based signature scheme can be used as a primitive block to design more complicated cryptographic protocols.
Key words: identity-based signature, ideal functionality, universally composable security
摘要: 在通用可组合安全性框架下定义了基于身份的数字签名方案的通用可组合安全性。证明了基于身份数字签名方案的通用可组合安全性与传统的安全性——在选择消息和选择身份攻击下的不可存在性伪造——之间的等价性。这一结果表明基于身份的数字签名方案可以作为安全的密码原语用于构建更复杂的密码协议。
