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 ...
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.
These are used to protect secure Web pages, encrypted email, and many other types of data. Breaking these would have significant ramifications for electronic privacy and security. Identifying cryptographic systems that may be secure against quantum algorithms is an actively researched topic under the field of post-quantum cryptography.
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 ...
The three-stage quantum cryptography protocol, also known as Kak's three-stage protocol [1] is a method of data encryption that uses random polarization rotations by both Alice and Bob, the two authenticated parties, that was proposed by Subhash Kak. [2]
In fact, this is the only possible protocol (in the classical or the quantum setting [1]) that gives the user information theoretic privacy for their query in a single-server setting. [2] There are two ways to address this problem: make the server computationally bounded or assume that there are multiple non-cooperating servers, each having a ...
U.S. intelligence agencies are scrambling to embrace the AI revolution, convinced they’ll otherwise be smothered in data as sensor-generated surveillance tech further blankets the planet. Years ...
"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 ...
