How to Compute an Isogeny on the Extended Jacobi Quartic Curves? [PDF]
International Journal of Electronics and Telecommunications, 2022 Computing isogenies between elliptic curves is a significant part of post-quantum cryptography with many practical applications (for example, in SIDH, SIKE, B-SIDH, or CSIDH algorithms).

Post-Quantum Security of COPA. [PDF]
Entropy (Basel)COPA 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. However, these works do not demonstrate the confidentiality of COPA in the quantum setting.

2021 IEEE Symposium on Security and Privacy (SP), 2021 In this paper we present PQ-WireGuard, a post-quantum variant of the handshake in the WireGuard VPN protocol (NDSS 2017). Unlike most previous work on post-quantum security for real-world protocols, this variant does not only consider post-quantum confidentiality (or forward secrecy) but also post-quantum authentication. To achieve this, we replace the

A post-quantum associative memory
Journal of Physics A: Mathematical and Theoretical, 2023 Abstract Associative memories are devices storing information that can be fully retrieved given partial disclosure of it. We examine a toy model of associative memory and the ultimate limitations to which it is subjected within the framework of general probabilistic theories (GPTs), which represent the most general class of physical ...

Post-quantum security of the sponge construction.. Post-Quantum Cryptography. [PDF]
PQCrypto 2018, 2018 We investigate the post-quantum security of hash functions based on the sponge construction. A crucial property for hash functions in the post-quantum setting is the collapsing property (a strengthening of collision-resistance). We show that the sponge construction is collapsing (and in consequence quantum collision-resistant) under suitable ...

Random Oracles in a Quantum World [PDF]
, 2011 The interest in post-quantum cryptography - classical systems that remain secure in the presence of a quantum adversary - has generated elegant proposals for new cryptosystems.

On the Security of the Dandelion Protocol
Mathematics, 2022 In this paper, we review the peer-to-peer blockchain transaction protocol, Dandelion, and develop an oracle-based model for its network and security. We formalize a series of security and functional criteria, such as unforgeability, non-repudiation, and ...

Quantum violations in the Instrumental scenario and their relations to the Bell scenario [PDF]
, 2019 The causal structure of any experiment implies restrictions on the observable correlations between measurement outcomes, which are different for experiments exploiting classical, quantum, or post-quantum resources. In the study of Bell nonlocality, these
