Quantum key distribution (QKD) exploits the laws of quantum physics to generate shared secret cryptographic keys and can detect eavesdroppers during the key generation process. However, previous QKD research has focused more on theory than practice.
Nowadays cryptography is applied in more and more applications. Most often asymmetric or hybrid systems are used, which are based on mathematical concepts. However, a promising family of quantum solutions tries to take over control. This article describes a technique of quantum key distribution called BB84. It gives an insight into quantum physics governing the proper operation of any system in quantum...
Recent misuse of wireless internet by terrorists has increased the need for security in the same. With ever growing technology both cryptographers, who encrypt messages, and cryptanalysts, who break those codes, have equal opportunities and facilities. Quantum Cryptography seems to be a promising solution providing absolute security in such communications. Its works by identifying the threats and...
