The paper presents the implementation of a quantum cryptography protocol for secure communication. As computing power increases, classical cryptography and key management schemes based on computational complexity become increasingly susceptible to brute force and cryptanalytic attacks. Current implementations of quantum cryptography are based on the BB84(More)

This paper presents the design and implementation of a new technology that can securely transfer symmetric encryption keys, e.g., Advanced Encryption Standard (AES) keys, over an optical fiber using a polarization-based channel. The integrity of the polarization channel against possible leakage of information is established. The polarization channel is used(More)
Contemporary implementations of Quantum Key Distribution are based on BB84, first proposed in 1984, and commercially implemented for limited market applications in the early 2000s. A major limitation of BB84 is that it requires no more than a single photon per time slot. But no device can reliably generate single photons with guaranteed periodicity. In this(More)
