Asymmetric Cryptosystem Using Careful Synchronization [PDF]
arXiv, 2023 We present public-private key cryptosystem which utilizes the fact that checking whether a partial automaton is carefully synchronizing is $PSPACE$-complete, even in the case of a binary alphabet.

Implementation Security in Quantum Key Distribution
Advanced Quantum Technologies, Volume 8, Issue 2, February 2025.The problem of implementation security in quantum key distribution (QKD) refers to the difficulty of meeting the requirements of mathematical security proofs in real‐life QKD systems. The present work provides a succint review on this topic, focusing on discrete‐variable QKD setups.

Analysis of the RSA-cryptosystem in abstract number rings
Журнал Белорусского государственного университета: Математика, информатика, 2020 Quantum computers can be a real threat to some modern cryptosystems (such as the RSA-cryptosystem). The analogue of the RSA-cryptosystem in abstract number rings is not affected by this threat, as there are currently no factorization algorithms using ...

The MOR cryptosystem and finite $p$-groups [PDF]
arXiv, 2013 The ElGamal cryptosystem is the most widely used public key cryptosystem. It uses the discrete logarithm problem as the cryptographic primitive. The MOR cryptosystem is a similar cryptosystem. It uses the discrete logarithm problem in the automorphism group as the cryptographic primitive.
