Post-Quantum Security of COPA [PDF]
EntropyCOPA is a notable authenticated online cipher and was one of the winning proposals for the CAESAR competition. Current works describe how to break the existentially unforgeable under quantum chosen message attack (EUF-qCMA) of COPA.

Triplex: an Efficient and One-Pass Leakage-Resistant Mode of Operation
Transactions on Cryptographic Hardware and Embedded Systems, 2022 This paper introduces and analyzes Triplex, a leakage-resistant mode of operation based on Tweakable Block Ciphers (TBCs) with 2n-bit tweaks. Triplex enjoys beyond-birthday ciphertext integrity in the presence of encryption and decryption leakage in a ...

Authenticated Encryption Schemes: A Systematic Review
IEEE Access, 2022 Authenticated encryption (AE) is a cryptographic construction that simultaneously protects confidentiality and integrity. A considerable amount of research has been devoted to the area since its formal inception in 2000.

Avalanche Effect in Improperly Initialized CAESAR Candidates [PDF]
Electronic Proceedings in Theoretical Computer Science, 2016 Cryptoprimitives rely on thorough theoretical background, but often lack basic usability features making them prone to unintentional misuse by developers. We argue that this is true even for the state-of-the-art designs.

Analyzing the Linear Keystream Biases in AEGIS
IACR Transactions on Symmetric Cryptology, 2020 AEGIS is one of the authenticated encryption designs selected for the final portfolio of the CAESAR competition. It combines the AES round function and simple Boolean operations to update its large state and extract a keystream to achieve an excellent ...
