Deniable Functional Encryption [PDF]
, 2016 Deniable encryption, first introduced by Canetti et al. [14], allows a sender and/or receiver of encrypted communication to produce fake but authentic-looking coins and/or secret keys that "open" the communication to a different message. Here we initiate its study for the more general case of functional encryption FE, as introduced by Boneh et al. [12],

Provably sender-deniable encryption scheme [PDF]
Computer Science Journal of Moldova, 2015 The use of the well known provably secure public-key cryptoscheme by Rabin is extended for the case of the deniable encryption. In the proposed new sender-deniable encryption scheme the cryptogram is computed as coefficients of quadratic congruence, the

Deniable Authentication on the Internet [PDF]
, 2008 Deniable authentication is a technique that allows one party to send messages to another while the latter can not prove to a third party the fact of communication. In this paper, we formalize a natural notion of deniable security and naturally extend the basic authenticator theorem by Bellare et al. [1] to the setting of deniable authentication.

New Approaches for Deniable Authentication [PDF]
Journal of Cryptology, 2005 Here is proposed a new technique for Deniable Authentication, which allows a Sender to authenticate a message for a Receiver in a way that the Receiver can not prove to a third party that authentication took place; also some terminological issues are made more precise.

Proceedings on Privacy Enhancing Technologies, 2023 In this work we propose time-deniable signatures (TDS), a new primitive that facilitates deniable authentication in protocols such as DKIM-signed email. As with traditional signatures, TDS provide strong authenticity for message content, at least {\em for a sender-chosen period of time}.

ID-Based Digital Signatures with Security Enhanced Approach
Journal of Telecommunications and Information Technology, 2023 n the paper the ID-based digital signatures with signer’s protection in case of the private key compromising is investigated. The proposed protocols have two main ingredients.

Deniable encryption in a Quantum world
Proceedings of the 54th Annual ACM SIGACT Symposium on Theory of Computing, 2022 (Sender-)Deniable encryption provides a very strong privacy guarantee: a sender who is coerced by an attacker into "opening" their ciphertext after-the-fact is able to generate "fake" local random choices that are consistent with any plaintext of their choice.

A Small State’s Cyber Posture: Deterrence by Punishment and Beyond
Scandinavian Journal of Military Studies, 2023 This study explores a small-state’s offensive cyber capabilities as a deterrent against great-power cyber hostilities. More specifically, it poses the question: Could Norway successfully deter hostile cyber operations of greater powers, notably China and

Fully Deniable Interactive Encryption [PDF]
, 2020 Deniable encryption (Canetti et al., Crypto 1996) enhances secret communication over public channels, providing the additional guarantee that the secrecy of communication is protected even if the parties are later coerced (or willingly bribed) to expose ...

Hiding Messages in Secure Connection Transmissions with Full-Duplex Overt Receiver
Sensors, 2022 This paper considers hiding messages in overt transmissions with a full-duplex receiver, which emits artificial noise to secure its transmission connection while a transmitter opportunistically sends a covert message to a covert user.
