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 ...
BB84 is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984. [1] It is the first quantum cryptography protocol. [2] The protocol is provably secure assuming a perfect implementation, relying on two conditions: (1) the quantum property that information gain is only possible at the expense of disturbing the signal if the two states one is trying to ...
In cryptography, Combined Elliptic-Curve and Post-Quantum 2 (CECPQ2) is a quantum secure modification to Transport Layer Security (TLS) 1.3 developed by Google. It is intended to be used experimentally, to help evaluate the performance of post quantum key-exchange algorithms on actual users' devices.
If we let X and Y be entangled quantum states instead, then X cannot be cloned, and this sort of "polygamous" outcome is impossible. The monogamy of entanglement has broad implications for applications of quantum mechanics ranging from black hole physics to quantum cryptography, where it plays a pivotal role in the security of quantum key ...
Quantum computing has significant potential applications in the fields of cryptography and cybersecurity. Quantum cryptography, which relies on the principles of quantum mechanics, offers the possibility of secure communication channels that are resistant to eavesdropping.
Kyber is a key encapsulation mechanism (KEM) designed to be resistant to cryptanalytic attacks with future powerful quantum computers.It is used to establish a shared secret between two communicating parties without an attacker in the transmission system being able to decrypt it.
Timeline for the transition to CNSA 2.0. The suite includes: Advanced Encryption Standard with 256 bit keys; Elliptic-curve Diffie–Hellman and Elliptic Curve Digital Signature Algorithm with curve P-384; SHA-2 with 384 bits, Diffie–Hellman key exchange with a minimum 3072-bit modulus, and; RSA with a minimum modulus size of 3072.

"The six-state protocol is a discrete-variable protocol for quantum key distribution that permits tolerating a noisier channel than the BB84 protocol." [ 3 ] (2011, Abruzzo). SSP produces a higher rate of errors during attempted eavesdropping, thus making it easier to detect errors, as an eavesdropper must choose the right basis from three ...
