Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. Currently used popular public-key encryption and signature schemes can be broken by quantum adversaries. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical communication. For example, it is impossible to copy data encoded in a quantum state and the very act of reading data encoded in a quantum state changes the state. This is used to detect eavesdropping in quantum key distribution.

Alice and Bob’s quest through the fascinating quantum mechanics world as a way to avoid archvilainess Eve eavesdropping. In 1994, Peter Shor showed that many of the cryptosystems used today can be broken using a quantum computer. This idea will be explained together with a short overview of qubit systems. Next, we will see how quantum computing gives rise to the possibility of quantum key distribution with unparalleled security. We will end with a brief discussion on post-quantum cryptography concepts.

Slides from a talk on Quantum Key Distribution presented to the Silicon Valley Cyber Security Meetup group. This talk covered a basic intuitive description of the BB84 protocol as well as brief notes on current QKD techniques and vulnerabilities that leave them hackable if not crackable. These slides prioritize conveying intuitive understanding over exact implementation details so some details of the BB84 protocol are different (e.g. using qubit bases rather than polarization bases) or glossed over.

Quantum Cryptography (QKD) uses the laws of Quantum Mechanics to create new cryptographic primitives. Precisely, this technique is based on two laws of quantum mechanics, namely uncertainty principle and no-cloning theorem. The best known QKD is the BB84 protocol published by Bennett and Brassard in 1984. Since then, various QKD protocols have been developed for example a B92 protocol. This latter is similar to that of BB84but this time using only two non-orthogonal states of the four states of BB84. In this work, we develop the java simulation B92 protocol and we give some details of the implementation. Next, we show by an example how Alice (Initiator) can configure the protocol parameters before execution. Finally, we give the statistical results allowing to compare this protocol with that of BB84.

Cryptography is an art and science of secure communication. Here the sender and receiver are guaranteed the security through encryption of their data, with the help of a common key. Both the parties should agree on this key prior to communication. The cryptographic systems which perform these tasks are designed to keep the key secret while assuming that the algorithm used for encryption and decryption is public. Thus key exchange is a very sensitive issue. In modern cryptographic algorithms this security is based on the mathematical complexity of the algorithm. But quantum computation is expected to revolutionize computing paradigm in near future. This presents a challenge amongst the researchers to develop new cryptographictechniques that can survive the quantum computing era. This paper reviews the radical use of quantum mechanics for cryptography.

Quantum Cryptography is the one of the most successul application of quantum computing/information theory. cryptography is the coding and decoding of secret messages. Quantum Key Distribution uses the laws of quantum mechanics, we can distribute keys in perfect secrecy.
