| Popis: | In the field of social survey of misconduct and legal consultation, the features of confidentiality, integrity, deniable authentication, and non-repudiation are needed for the sake of preserving privacy. For this special kind of application scenario, we propose an efficient deniable authentication encryption scheme. Our scheme can achieve the four secure features in a single logical step. And compared with the latest scheme, our scheme reduces the computational cost of encryption by about 30%, reduces computational cost of decryption by about 50%, and reduces the length of ciphertext by about 33%. Its security is shown in the random oracle model. |
