Design a New Protocol and Compare with BB84 Protocol for Quantum Key Distribution

摘要

Quantum key distribution is the latest advancement in quantum cryptography. There are several QKD protocols like BB84, B92, Ekert91, COW, SARG04, out of which BB84 is the first protocol developed in 1984. In this paper, we are discussing first about the working of BB84 protocol and then proposing a new protocol which is a variation over BB84 protocol, second the design of simulation setup is discussed, and then we compared the performance of BB84 with the proposed protocol and proved it much better in case of capacity and error estimation. Object-oriented approach is used in the simulation designing for new protocol and BB84 protocol.
