On the (Im)possibility of Commitment over Gaussian Unfair Noisy Channels
Commitment is a key primitive which resides at the heart of several cryptographic protocols. Noisy channels can help realize information-theoretically secure commitment schemes; however, their imprecise statistical characterization can severely impair such ...
2023Extractable Witness Encryption for the Homogeneous Linear Equations Problem
Serge Vaudenay, Bénédikt Minh Dang Tran
Witness encryption is a cryptographic primitive which encrypts a message under an instance of an NP language and decrypts the ciphertext using a witness associated with that instance. In the current state of the art, most of the witness encryption construc ...
Springer2023Security in the Presence of Quantum Adversaries
With the looming threat of large-scale quantum computers, a fair portion of recent cryptographic research has focused on examining cryptographic primitives from the perspective of a quantum adversary. Shor's 1994 result revealed that quantum computers can ...
