Insinuations, Indirect Speech Acts, and Deniability
Studia Semiotyczne, 2023 DOI: https://doi.org/10.26333/sts.xxxvi2.03 Insinuations are indirect speech acts done for various reasons: a speaker S may insinuate P (i) because an insinuation is more polite, and S can save face by non-explicitly saying P (Brown, Levinson, 1987 ...

Real-World Deniability in Messaging [PDF]
Proceedings on Privacy Enhancing TechnologiesThis work explores real-world deniability in messaging. We propose a formal model that considers the entire messaging system to analyze deniability in practice. Applying this model to the Signal application and DKIM-protected email, we demonstrate that these systems do not offer practical deniability guarantees. Additionally, we analyze 140 court cases

CoRR, 2022 Steganography conceals the secret message into the cover media, generating a stego media which can be transmitted on public channels without drawing suspicion. As its countermeasure, steganalysis mainly aims to detect whether the secret message is hidden in a given media. Although the steganography techniques are improving constantly, the sophisticated

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}.

On the Cryptographic Deniability of the Signal Protocol [PDF]
, 2020 Offline deniability is the ability to a-posteriori deny having participated in a particular communication session. This property has been widely assumed for the Signal messaging application, yet no formal proof has appeared in the literature.

Building a Privacy-Preserving Blockchain-Based Bidding System: A Crypto Approach
IEEE Access, 2022 Blockchain-based bidding systems are becoming increasingly popular nowadays. Due to the properties of blockchain, bidding records are unchangeable. With existing encryption techniques, these bidding records can only be shared by the bidder and the seller.

Faking It Is Hard to Do: Entrepreneurial Norm Enforcement and Suspicions of Deviance [PDF]
Sociological Science, 2017 Recent research suggests that many norms may be upheld by closet deviants who engage in enforcement so as to hide their deviance. But various empirical accounts indicate that audiences are often quite sensitive to this ulterior motive.

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.

Reversible and Plausibly Deniable Covert Channels in One-Time Passwords Based on Hash Chains
Applied Sciences, 2021 Covert channels enable stealthy communications over innocent appearing carriers. They are increasingly applied in the network context. However, little work is available that exploits cryptographic primitives in the networking context to establish such ...

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],
