In cryptography, post-quantum cryptography (PQC) (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer. The problem with … See more Currently post-quantum cryptography research is mostly focused on six different approaches: Lattice-based cryptography This approach includes cryptographic systems such as See more A public-key system demonstrates a property referred to as perfect forward secrecy when it generates random public keys per session for the purposes of key agreement. This means that the compromise of one message cannot lead to the compromise … See more One of the main challenges in post-quantum cryptography is considered to be the implementation of potentially quantum safe algorithms into existing systems. There are tests … See more • NIST Post-Quantum Cryptography Standardization • Quantum cryptography – cryptography based on quantum mechanics See more In cryptography research, it is desirable to prove the equivalence of a cryptographic algorithm and a known hard mathematical problem. These … See more One common characteristic of many post-quantum cryptography algorithms is that they require larger key sizes than commonly used "pre-quantum" public key algorithms. There are often tradeoffs to be made in key size, computational efficiency and ciphertext or … See more Open Quantum Safe (OQS) project was started in late 2016 and has the goal of developing and prototyping quantum-resistant cryptography. It aims to integrate current post-quantum schemes in one library: liboqs. liboqs is an open source C library for quantum … See more

Xor-And-Inverter Graphs for Quantum Compilation

WebJun 20, 2024 · There are two classical NP-hard problems in lattice-based cryptography: Shortest Vector Problem (SVP): Given a lattice, to find the shortest non-zero vector in the lattice. In the graph, the vector s s is the shortest one. The SVP problem is NP-hard only under some assumptions. Closest Vector Problem (CVP). WebFor example, Graph Isomorphism is a standard problem admitting a statistical zero-knowledge proof; a famous result of Goldwasser and Sipser shows that the Graph Isomorphism problem is in the so-called $\mathsf{coAM}$ complexity class. We can ask similar questions in the quantum setting. small pole barn house plans
