一种基于身份和密钥封装机制的加密方案
Encryption Scheme Based on Identity and Key Encapsulation Mechanism
摘要
Abstract
This paper proposes a new Identity-based and Key Encapsulation Mechanism(IB-KEM) encryption scheme. The symmetric encryption scheme is used to encryption and description for message, and the identity-based encryption scheme is used to manage the symmetric encryption key. The new scheme is a natural extension of the encryption scheme which is provably secure under chosen ciphertext attack in the standard model. The security of the new scheme is under Decisional DifTie-Hellman(DDH) assumption. The security analysis shows that the new scheme is indistinguishable under adaptive chosen ciphertext attack.关键词
