Quantum-resistant algorithms are cryptographic methods designed to remain secure even if someone uses a powerful quantum computer to try to break them. Traditional encryption methods like RSA and ECC could be easily broken by quantum computers, making current digital security vulnerable. Quantum-resistant algorithms aim to protect data and communications from future threats by using mathematical…

Quantum Key Distribution
Quantum Key Distribution (QKD) is a method of securely sharing encryption keys between two parties using the principles of quantum mechanics. It ensures that any attempt to intercept or eavesdrop on the key exchange is detectable, making it highly secure. QKD does not transmit the message itself, only the key needed to decrypt secure communications.
Quantum Random Number Generation
Quantum random number generation is a method of creating random numbers by using the unpredictable behaviour of particles in quantum physics. Unlike traditional methods that use computer algorithms, quantum methods rely on natural randomness at the smallest scales. This makes the numbers produced truly random, rather than being based on patterns or formulas.
Quantum Cryptography Protocols
Quantum cryptography protocols are methods that use the principles of quantum physics to secure the transfer of information. These protocols rely on the behaviour of particles like photons to ensure that any attempt to intercept or eavesdrop on a message can be detected. Unlike traditional encryption, quantum cryptography offers a way to create and share…
Quantum Error Correction Codes
Quantum error correction codes are methods used to protect quantum information from errors caused by noise, interference, or imperfect operations. In quantum computing, errors can easily occur because quantum bits, or qubits, are very sensitive to their environment. These codes use additional qubits and clever techniques to detect and fix mistakes without directly measuring or…
Secure Time Synchronisation
Secure time synchronisation is the process of ensuring that computer systems and devices keep the same accurate time, while also protecting against tampering or interference. Accurate time is important for coordinating events, logging activities, and maintaining security across networks. Secure methods use cryptography and authentication to make sure that time signals are genuine and have…
Cryptographic Token Standards
Cryptographic token standards are agreed rules and formats for creating, managing, and transferring digital tokens using blockchain technology. These standards ensure that tokens can work together across different platforms and services. Popular standards define things like how tokens are created, how they can be sent or received, and what information they hold.
Cryptographic Proof Systems
Cryptographic proof systems are methods used to show that something is true without revealing all the details. They allow one party to convince another that a statement is correct using mathematical techniques. These systems are important for privacy and security in digital communication and transactions.
Secure Channel Establishment
Secure channel establishment is the process of creating a private and protected communication link between two parties, so that information can be exchanged without being intercepted or tampered with by others. This usually involves verifying the identity of each party and using encryption to keep messages confidential. Secure channels are important for protecting sensitive data,…
Secure Randomness Generation
Secure randomness generation is the process of creating unpredictable numbers or data that cannot be guessed or predicted by attackers. It is essential for protecting sensitive information, such as passwords, encryption keys, and digital tokens. Secure randomness relies on specialised algorithms and hardware that gather random information from unpredictable physical processes or system events.
