Quantum Cryptography and Its Uncrackability
Li Fan · Journal of Shanxi University · 2009
At the time when man enter the Information Age in the twenty-first century,how could we guarantee that the communications systems can't be decrypted? In this respect,quantum cryptography has made great progress.By analyzing the development of cryptography both scientifically and philosophically from the non-quantum cryptography phase to the quantum cryptography phase,we conclude that the ancient cryptography is of weak uncrackability,and when it developed into the stage of the classical cryptography its theory and practice take on the strong-uncrackability,while the quantum cryptography tends to be uncrakable,and it is gradually becoming imperatively uncrakable.
