Generalized Feistel Structures Based on Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2022 A generalized Feistel structure (GFS) is a classical approach to construct a block cipher from pseudorandom functions (PRFs). Coron et al. at TCC 2010 instantiated a Feistel structure with a tweakable block cipher (TBC), and presented its provable ...

Provably Secure Steganography [PDF]
IEEE 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 Secure Parallel Gadgets
IACR 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
IACR 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.

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

A Provable Secure Session Key Distribution Protocol Based on NSSK for In-Vehicle CAN Network
Mathematics, 2022 Many CAN-based session key sharing approaches are based on the group key scheme, which can easily lead advanced adversaries to infiltrate all ECUs (electronic control units) in the network if the sharing key is leaked.

Provably Quantum-Secure Tweakable Block Ciphers
IACR 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.
