Practical Deniable Encryption

2008
A party using encrypted communication or storing data in an encrypted form might be forced to show the corresponding plaintext. It may happen for law enforcement reasons as well as for evil purposes. Deniable encryption scheme introduced by Canetti et al.

Heterogeneous Deniable Authenticated Encryption Protocol

2020
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.

Dual encryption and plausible deniability

Computer Law & Security Report, 2004
Abstract Proposals, to allow law enforcement agencies to obtain access to encryption keys, raise interesting questions in regard to the subterfuge that a criminal organisation might employ to safeguard secret data. The situation has common ground with methods used for the plausible deniability of the presence of secret files.

Abuse-resistant deniable encryption

Computer Standards and Interfaces
Deniable encryption (DE) allows private communication over an insecure channel even under the coercion. That is, after an adversary forces communication participants to reveal their secret keys and randomness used during the communication, the message ...

Secret Sharing Deniable Encryption Technique

2017
Deniable Encryption was introduced to ensure that the sender and/or receiver in the communication able to create and encrypt fake messages into different ciphertexts to protect the real messages from a coercing adversary. Numerous past works have been proposed to cater the issues of coercible communication.

Deniable Fully Homomorphic Encryption from Learning with Errors

2021
We define and construct Deniable Fully Homomorphic Encryption based on the Learning With Errors (LWE) polynomial hardness assumption. Deniable FHE enables storing encrypted data in the cloud to be processed securely without decryption, maintaining deniability of the encrypted data, as well the prevention of vote-buying in electronic voting schemes ...

No-Key Protocol for Deniable Encryption

2018
There is proposed a new method for deniable encryption based on commutative transformations. The method has been used to design the deniable encryption protocol resistant to the passive coercive attacks, which uses no pre-shared secret keys and no pre-exchanged public keys.

Weak and Strong Deniable Authenticated Encryption: On their Relationship and Applications

2018 16th Annual Conference on Privacy, Security and Trust (PST), 2018
Consider a scenario in which a whistleblower (Alice) would like to disclose confidential documents to ajournalist (Bob). Bob wants to verify that the messages he receives are really from Alice; at the same time, Alice does not want to be implicated if Bob is later compelled to (or decides to) disclose her messages, together with his secret key and any ...
