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 ...
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.
Six-state protocol can be implemented without a quantum computer using only optical technologies. SSP's three conjugate bases span is shown on Picture 1. [7] Pic. 1. Alice randomly generates a qubit string, encodes them using randomly chosen one of three bases, and sends string of qubits to Bob through the secured quantum channel.
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 ...
Quantum location authentication was first investigated by Kent in 2002, which he called ‘quantum tagging’, resulting in a filed US patent by Kent et al. in 2007, [22] and a publication in the academic literature in 2010, [15] after a paper on position-based quantum cryptography was published by Buhrman et al. [16] There is a no-go theorem ...
The process of quantum key distribution is not to be confused with quantum cryptography, as it is the best-known example of a quantum-cryptographic task. An important and unique property of quantum key distribution is the ability of the two communicating users to detect the presence of any third party trying to gain knowledge of the key.
The Commercial National Security Algorithm Suite (CNSA) is a set of cryptographic algorithms promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms. It serves as the cryptographic base to protect US National Security Systems information up to the top secret level, while the NSA plans for a ...
Three-stage quantum cryptography protocol (2006) is a method of data encryption that uses random polarization rotations by the two authenticated parties, to continuously encrypt data using single photons and can also be used for exchanging keys, with the possibility of multi-photon quantum cryptography and the ability to address man-in-the ...
