Hybrid schemes in a KEM-DEM structure is regarded as the most natural approach to public key encryption with IND-CCA security and practical efficiency. Traditional KEM is realized by public key scheme, which only provides confidentiality security for session key used by DEM. In 2005, combining the idea of signcryption with the KEM-DEM model hybrid encryption, Alexander proposed a signcryption KEM-DEM model hybrid signcryption primitive.

KEM-DEM结构的混合密码体制是获得IND-CCA安全最实际有效的方法，传统的KEM由公钥加密方案实现，仅提供DEM使用的会话密钥的保密性安全。2005年Alexander等人将签密的概念与KEM-DEM结构的混合密码体制相结合，提出了Signcryption KEM-DEM结构的混合签密。

By using the GUI program, the user can deal with practical problem conveniently: soil space distributing, soils parameter; having or no water and water distribution, loads distribution and values; earthquake condition; start element of KEM; pointing out the elements which displacement should be known and the displacement value.

编制的图形用户界面程序能使用户方便地在图形界面下，按照菜单和对话框的提示，人机交互输入KEM土体极限分析需要的所有资料：土体的空间分布情况，各土层的土体参数，有无地下水以及地下水的水位分布情况，外荷载的分布及大小，地震情况，划分初始的KEM土体单元，指定需要施加虚位移的土体单元及与其相应虚位移的大小。

For the unsuitabihty of the Tag-KEM/DEM to be used as multi-message hybrid encryptions, a new hybrid paradigm, KEM/Tag-DEM, is proposed with its security proof.
