Quantum Cryptography

Quantum cryptology describes the routine of quantum mechanical effects (in particular quantum pour forth and quantum computation) to perform cryptographic tasks or to break cryptographic systems. The phthisis of classic (i.e., non-quantum) cryptography to protect against quantum attackers is also often considered as quantum cryptography (in this case, one also speaks of post-quantum cryptography). Well-known examples of quantum cryptography be the use of quantum communication to securely exchange a key fruit (quantum mainstay diffusion) and the (hypothetical) use of quantum computers that would allow us to break varied popular public-key encryption and signature schemes (e.g., RSA and ElGamal). The advantage of quantum cryptography lies in the fact that it allows to achieve various cryptographic tasks that are be or conjectured to be impossible using only chaste (i.e., non-quantum) communication (see below for examples). In particular, quantum mechanics guarantee that totality quantum data disturbs that data; this can be used to agree an adversarys interference with a message. However, researches at NTNU showed that man-in-middle attacks are possible without detections in some implementations of quantum systems.
