摘要: 基于Signcryption KEM-DEM混合签密结构,提出一个内部攻击者安全模式下签密密钥封装的形式化定义,引入一个随机标签与验证算法来保证签密密钥封装在内部攻击者模式下的安全性。在形式化定义的基础上,对该定义在可证明安全概念下的保密性和数据完整性的安全进行讨论,给出相应的攻击游戏的安全模型。

Abstract: Based on Signcryption KEM-DEM hybrid signcryption construction, a formal definition of signcryption key encapsulation in insider security mode is proposed. In the definition, a random tag and a verification algorithm are introduced to provide the insider security of the new key encapsulation. Based on the formal definition, this paper discusses the confidentiality security and unforgeability security in concept of provably security. The security models based on attack games are proposed.

Key words: signcryption, key encapsulation, insider security, confidentiality security, unforgeability security
