The Open Quantum Safe (OQS) project was started in late 2016 and has the goal of developing and prototyping quantum-resistant cryptography. [64] [65] It aims to integrate current post-quantum schemes in one library: liboqs. [66] liboqs is an open source C library for quantum-resistant cryptographic algorithms. It initially focuses on key ...
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.
In principle, this method can be used for continuous, unbreakable encryption of data if single photons are used. [3] It is different from methods of QKD (quantum key distribution) for it can be used for direct encryption of data, although it could also be used for exchanging keys. Alice and Bob communicate safely using random polarization ...
The National Security Agency isn't just yearning for quantum computers that can break tough encryption -- it wants encryption that can protect against quantum computers, too. Officials have begun ...
The best way to secure your data is to use end-to-end encryption apps like Signal and WhatsApp, officials advised FBI Says Everyone Should Use Encryption Apps for Their Calls and Texts After China ...
For a chat encryption scenario using liboqs, replacing the extremely efficient, non-quantum-safe ECDH key exchange using Curve25519 was found to increase runtime by a factor of about 2.3 (1.5–7), an estimated 2.3-fold (1.4–3.1) increase in energy consumption, and have about 70 times (48–92) more data overhead.

PQXDH is an upgraded version of the X3DH protocol and uses both the quantum-resistant CRYSTALS-Kyber protocol as well as the old elliptic curve X25519 protocol. This ensures that an attacker must break both of the encryption protocols to gain access to sensitive data, mitigating potential security vulnerabilities the new protocol could have.
Post-Quantum Cryptography Standardization [1] is a program and competition by NIST to update their standards to include post-quantum cryptography. [2] It was announced at PQCrypto 2016. [ 3 ] 23 signature schemes and 59 encryption/ KEM schemes were submitted by the initial submission deadline at the end of 2017 [ 4 ] of which 69 total were ...
