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。

The KEM scheme in the KEM+DEM paradigm is used to encapsulate the symmetric key for a multi-message hybrid encryption, IND-CCAs security is proved. An instantiation is presented to show the requirement of IND-CCA2 security for KEM is not essential.
4证明了KEM+DEM混合加密范例中的KEM用于多消息混合加密中，即KEM+SKE，是IND-CCA_S安全的，并用一个实例说明了此时对KEM要求IND-CCA2不是必要的。

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. For the corresponding multi-message hybrid paradigm, KEM/Tag-SKE, security is also proved. Two constructions for IND-CCA secure Tag-DEMs are proposed with the security proof.
6鉴于Tag-KEM／DEM不宜用作多消息混合加密，提出一种新的混合加密范例KEM／Tag-DEM，证明了它作为一次混合加密时的安全性，以及对应的多消息混合加密KEM／Tag-SKE的安全性，给出了两种构造Tag-DEM的方法并证明了安全性。
