Quantum Encryption

ABSTRACT

Traditional cryptographic solutions have relied upon computationally intensive algorithms to encrypt information. But faster processors, new algorithms and specialized hardware have made these techniques susceptible to compromise, forcing classical encryption to evolve in order to ensure security. This is where quantum encryption comes in. The principle of quantum encryption is to pack and transmit information is subatomic dynamics and to assume that an eavesdropper trying to capture the message, would necessarily corrupt it and render it unreadable. Its based on Heisenberg Principle which asserts that at subatomic reality, the act of taking a measurement necessarily impacts the measured quantity, and thus measuring that quantity as it was without the act of measurement is in no way possible. The keys generated and disseminated using quantum cryptography are proved to be absolutely random and secure based on the laws of quantum mechanics, not upon the assumed security of complex mathematical algorithms. By sending the key encoded at the single-photon level on a photon-by-photon basis, quantum mechanics guarantees that the act of an eavesdropper intercepting a photon, even just to observe or read, will irretrievably change the information encoded on that photon. Therefore, the eavesdropper can neither copy nor clone a photon or read the information encoded on the photon without modifying it, a process that is provably detectable.
