摘要 利用标识密钥封装和数据封装混合加密技术对可证明安全签密进行研究,基于Bj￠rstad于2006年给出的一种可证明安全的签密混合结构签密标识密钥封装和数据封装(SCTK/DEM),提出了一个新的签密方案.通过对所提出方案结构的分析,证明了该方案具有SCTK/DEM混合结构,因此该签密方案是可证明安全的;同时通过与签密方案SCS的分析比较,说明了所提出签密方案的高效性. By using the Tag-KEM/DEM hybrid encryption technique and based on a provable security signeryption hybrid construction SCTK/DEM proposed by Bj （C/） rstad in 2006, a new signcryption scheme is given. By analyzing its hybrid construction, it is obtained that the proposed signcryption scheme is up to the SCTK/DEM construction. So, it has provable security. Moreover, compared with the famous signcryption scheme SCS, the high efficiency of our proposed scheme is shown at the same time.
