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。
