Network Coding-Based Post-Quantum Cryptography [PDF]
IEEE Journal on Selected Areas in Information Theory, 2021 We propose a novel hybrid universal network-coding cryptosystem (HUNCC) to obtain secure post-quantum cryptography at high communication rates. The secure network-coding scheme we offer is hybrid in the sense that it combines information-theory security with public-key cryptography.

Gaussian Post-selection for Continuous Variable Quantum Cryptography [PDF]
, 2012 We extend the security proof for continuous variable quantum key distribution protocols using post selection to account for arbitrary eavesdropping attacks by employing the concept of an equivalent protocol where the post-selection is implemented as a ...

Post-selection technique for quantum channels with applications to quantum cryptography [PDF]
, 2008 We propose a general method for studying properties of quantum channels acting on an n-partite system, whose action is invariant under permutations of the subsystems.

HybridPKE: A forward-secure non-interactive quantum-safe hybrid key exchange scheme
Engineering Science and Technology, an International Journal, 2022 The schemes submitted to NIST call for standardization of post-quantum cryptography have some common drawbacks in terms of decryption failure probability, scalability, and switching issues from pre-quantum to post- quantum cryptography. In this paper, we

Quantum key distribution based on selective post-processing in passive optical networks [PDF]
, 2014 One of the main obstacles to the widespread adoption of quantum cryptography has been the difficulty of integration into standard optical networks, largely due to the tremendous difference in power of classical signals compared with the single quantum ...

Isogeny-based post-quantum key exchange protocols [PDF]
, 2020 The goal of this project is to understand and analyze the supersingular isogeny Diffie Hellman (SIDH), a post-quantum key exchange protocol which security lies on the isogeny-finding problem between supersingular elliptic curves.

Why Quantum Bit Commitment And Ideal Quantum Coin Tossing Are Impossible [PDF]
, 1997 There had been well known claims of unconditionally secure quantum protocols for bit commitment. However, we, and independently Mayers, showed that all proposed quantum bit commitment schemes are, in principle, insecure because the sender, Alice, can ...
