Abstract: Signcryption is a new cryptographic technology,which simultaneously fulfills both the function of digital signature and public key encryption in a logically single step,and more efficient than the traditional “signature followed by encryption” approach.The paper points out the weakness of the previous signcryption scheme proposed by ZHANG Jianhong et al.,and constructs a new signcryption scheme.The new scheme provides message confidentiality,non-repudiation,forward secrecy,and public verifiability.So,it is simple and can be set up easily.
Key words: signcryption, multi-signcryption, forward secrecy, public verifiability
摘要: 签密技术能在一个逻辑步骤内同时实现签名和加密两项功能,相比较以往的“先签名后加密”有较高的效率。克服张键红等人提出的多重签密模型的不足,构造了一个新的多重签密方案。该方案的优点:安全性上实现了消息的保密性、不可否认性、可公开验证性、前向安全性,能抗合谋攻击,安全性能高;签密算法和验证算法复杂度小,灵活性好;方案简洁易于实际操作。
关键词: 签密, 多重签密, 前向安全性, 可公开验证性
