Quantum cryptography - Wikipedia
Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. [1] [2] The best known example of quantum cryptography is quantum key distribution, which offers an information-theoretically secure solution to the key exchange problem. The advantage of quantum cryptography lies in the fact that it ...
What Is Quantum Cryptography? - IBM
2023年12月1日 · Quantum cryptography (also known as quantum encryption) refers to various cybersecurity methods for encrypting and transmitting secure data based on the naturally occurring and immutable laws of quantum mechanics.
Quantum Cryptography and Quantum Encryption Explained
Quantum cryptography uses the laws of quantum physics to transmit private information in a way that makes undetected eavesdropping impossible. Quantum key distribution (QKD), the most widely studied and viable method of quantum cryptography, uses a series of photons to transmit a secret, random sequence, known as the key.
Quantum Cryptography - GeeksforGeeks
2023年3月21日 · Quantum Cryptography works on the principle of quantum entanglement, which is a phenomenon where two particles are correlated in a way that the state of one particle affects the state of the other particle, even when they are separated by a large distance.
What is Quantum-Safe Cryptography? - IBM
2024年9月4日 · Quantum cryptography (also known as quantum encryption) refers to various cybersecurity methods for encrypting and transmitting secure data based on the naturally occurring and immutable laws of quantum mechanics.
Cryptography in the Quantum Age | NIST - National Institute of ...
2018年3月21日 · Quantum cryptography is designed to protect communications between two trustworthy parties from being intercepted by an eavesdropper. But what if the person on the other side is a cyberattacker? Eavesdroppers are currently not the biggest concern in cybersecurity.

2023年5月12日 · Quantum cryptography uses the qubit of quantum entanglement to create an unbreakable connection between the sender and receiver. Creating quantum-safe cryptographic algorithms is one of the most vital functions of quantum cryptography.
Modern Cryptography: Theory and Applications - Computer …
Quantum cryptography, which uses photons and relies on the laws of quantum physics instead of "extremely large numbers," is the cutting edge discovery which seems to guarantee privacy even when assuming eavesdroppers with unlimited computing powers.
Post-quantum cryptography - Wikipedia
Post-quantum cryptography (PQC), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are currently thought to be secure against a cryptanalytic attack by a quantum computer.Most widely-used public-key algorithms rely on the difficulty of one of three mathematical problems: …
