Deniable authenticated encryption can achieve confidentiality and deniable authentication in a logical single step. Such a cryptographic primitive simplifies the design of cryptographic scheme and reduces the cost of computation and communication. In this paper, we propose a heterogeneous deniable authenticated encryption scheme called HDAE. The proposed scheme permits a sender in a public key infrastructure environment to transmit a message to a receiver in an identity-based environment. Our design utilizes tag-key encapsulation mechanism (tag-KEM) and data encapsulation mechanism (DEM) hybrid encryption methods, which is especially applicable in some privacy protection occasions. In addition, we give how to design an HDAE scheme utilizing a heterogeneous deniable authenticated tag-KEM (HDATK) and a DEM. We also construct an HDATK scheme and provide security proof in the random oracle model. Comprehensive analysis shows that our scheme is efficient and secure. |
