Good Gottesman-Kitaev-Preskill codes from the NTRU cryptosystem [PDF]

Quantum
We introduce a new class of random Gottesman-Kitaev-Preskill (GKP) codes derived from the cryptanalysis of the so-called NTRU cryptosystem. The derived codes are $good$ in that they exhibit constant rate and average distance scaling $\Delta \propto \sqrt{

Improved Quantum Linear Attacks and Application to CAST

IACR Transactions on Symmetric Cryptology
This paper studies quantum linear key-recovery attacks on block ciphers. The first such attacks were last-rounds attacks proposed by Kaplan et al. (ToSC 2016), which combine a linear distinguisher with a guess of a partial key.

Cryptanalysis of Symmetric Key Schemes using Classical and Quantum Techniques

, 2023
Symmetric key cryptography refers to the encryption methods in which the same key is used by both the sender and the receiver. Cryptanalysis is a process of finding vulnerabilities in cryptographic algorithms in order to distinguish the algorithm, or to ...

How to distinguish between a block cipher and a random permutation by lowering the input entropy [PDF]

, 2001
IEEE 35th International Carnahan Conference on Security Technology. Londres, 16-19 October 2001A novel cryptanalysis technique is presented, and its suitability for distinguishing a block cipher algorithm or a hash function from a random permutation is ...

A new non-commutative key exchange protocol on combinatorial semigroup

Automatika
Since the launch of the post-quantum cryptography standardization project by NIST, post-quantum cryptography has become a prominent research area. Non-commutative cryptography constructed using NP-complete problems is widely regarded resistant to quantum

New results on symmetric quantum cryptanalysis (Keynote speaker) [PDF]

, 2018
International audienceThe security of symmetric cryptography is completely based on cryptanalysis: we only gain confidence in the security of a symmetric primitive through extensive and continuous scrutiny.

Classical and quantum cryptanalysis of lattices and codes [PDF]

This thesis studies the security of lattice-based and code-based cryptography, two leading approaches to post-quantum cryptography. Although several lattice-based and code-based schemes have been selected for standardization and deployment, these schemes
