- Abstract
- To provide security against active coercive attacks there is included the entity authentication stage in the protocol for public-key deniable encryption. During the authentication stage it is performed a hidden exchange of the single-use public keys with which the users computes the session common secret key. The last is used for encrypting the sent secret message. Simultaneously it is encrypted a fake message using receiver's public key. Two intermediate ciphertexts are used to generate the single ciphertex that is computationally indistinguishable from the ciphertext potentially generated in the process of the probabilistic public encryption of the fake message. The proposed deniable encryption scheme includes the probabilistic public encryption algorithm associated with the ciphertext sent via public channel.
