Learning with Errors is easy with quantum samples

, 2018
Learning with Errors is one of the fundamental problems in computational learning theory and has in the last years become the cornerstone of post-quantum cryptography.

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 ...

Unconditional security at a low cost [PDF]

, 2006
By simulating four quantum key distribution (QKD) experiments and analyzing one decoy-state QKD experiment, we compare two data post-processing schemes based on security against individual attack by L\"{u}tkenhaus, and unconditional security analysis by ...

Post Quantum Cryptography from Mutant Prime Knots

, 2010
By resorting to basic features of topological knot theory we propose a (classical) cryptographic protocol based on the `difficulty' of decomposing complex knots generated as connected sums of prime knots and their mutants.

Post-Quantum Delegated Proof of Luck for Blockchain Consensus Algorithm

Applied Sciences
The advancements in quantum computing and the potential for polynomial-time solutions to traditional public key cryptography (i.e., Rivest–Shamir–Adleman (RSA) and elliptic-curve cryptography (ECC)) using Shor’s algorithm pose a serious threat to the ...

Device-independent quantum key distribution from computational assumptions

New Journal of Physics, 2021
In device-independent quantum key distribution (DIQKD), an adversary prepares a device consisting of two components, distributed to Alice and Bob, who use the device to generate a secure key.
