Provably Secure Steganography [PDF]

open access: yesIEEE Transactions on Computers, 2002
Informally, steganography is the process of sending a secret message from Alice to Bob in such a way that an eavesdropper (who listens to all communications) cannot even tell that a secret message is being sent. In this work, we initiate the study of steganography from a complexity-theoretic point of view.

Provable Security of SP Networks with Partial Non-Linear Layers

open access: yesIACR Transactions on Symmetric Cryptology, 2021
Motivated by the recent trend towards low multiplicative complexity blockciphers (e.g., Zorro, CHES 2013; LowMC, EUROCRYPT 2015; HADES, EUROCRYPT 2020; MALICIOUS, CRYPTO 2020), we study their underlying structure partial SPNs, i.e., Substitution ...

Provable Secure Parallel Gadgets

open access: yesIACR Transactions on Cryptographic Hardware and Embedded Systems, 2023
Side-channel attacks are a fundamental threat to the security of cryptographic implementations. One of the most prominent countermeasures against side-channel attacks is masking, where each intermediate value of the computation is secret shared, thereby concealing the computation’s sensitive information.

Beyond-Birthday-Bound Security for 4-round Linear Substitution-Permutation Networks

open access: yesIACR Transactions on Symmetric Cryptology, 2020
Recent works of Cogliati et al. (CRYPTO 2018) have initiated provable treatments of Substitution-Permutation Networks (SPNs), one of the most popular approach to construct modern blockciphers.

Public Key Encryption Supporting Plaintext Equality Test and User-Specified Authorization [PDF]

open access: yes, 2011
In this paper we investigate a category of public key encryption schemes which supports plaintext equality test and user-specified authorization. With this new primitive, two users, who possess their own public/private key pairs, can issue token(s) to a ...

On one Block Cipher Mode of Operation Used to Protect Data on Block-Oriented Storage Devices

open access: yesСовременные информационные технологии и IT-образование, 2022
This research purpose is to develop a reduction-based method for analysis of cryptographic properties of block cipher modes of operation in context of full disk encryption (FDE) via provable security technique, to study weaknesses of widely spread among ...

Provably Secure Encryption Schemes With Zero Setup and Linear Speed by Using Rubik’s Cubes

open access: yesIEEE Access, 2020
Recently, new paradigms for designing modern cryptographic schemes were proposed based on Rubik's rotations. However, most of them lack rigorous provable security reductions.

Provably Quantum-Secure Tweakable Block Ciphers

open access: yesIACR Transactions on Symmetric Cryptology, 2021
Recent results on quantum cryptanalysis show that some symmetric key schemes can be broken in polynomial time even if they are proven to be secure in the classical setting.
