Quantum Cryptography

Paper Summary:

This paper examines how quantum cryptography is a fast growing form of encryption that is not based upon the difficulty of mathematical algorithms and instead employs quantum physics to encrypt information on the physical level. It emphasizes the need for an innovative cipher as well as the need to inform the IT community regarding the commercial application of quantum cryptography. It also provides a broad overview of the quantum cryptographic protocol and operation using fiber optic media.

From the Paper:

"The integrity of information between sender and receiver relies upon secure channels and more importantly the ability to protect the information from unauthorized recipients. The transmission of information can be compromised when a third party listens in on the transmission media measuring the physical object. Consequently, the eavesdropper can effectively intercept the contents of a communication. Certain types of classical cryptography have proven vulnerable to the interception of data and the incident can remain undetected during the entire transmission. This idea of a man-in-the-middle attack on communication media using quantum cryptography is not possible due to the laws of quantum mechanics. Quantum superposition's and quantum entanglement are two properties of quantum physics used to detect eavesdropping. "
