Quantum stream cipher based on optical communications
In 2000, an attractive new quantum cryptography was discovered by H.P.Yuen based on quantum communication theory. It is applicable to direct encryption, for example quantum stream cipher based on Yuen protocol(Y-00), with high speeds and for long distance by sophisticated optical devices which can work under the average photon number per signal light pulse:< n >= 1000 ∼ 10000. In addition, it m...
متن کاملSecurity of Y-00 and similar quantum cryptographic protocols
It is claimed in Phys. Lett. A by T. Nishioka et al. [327 (2004) 28–32] that the security of Y-00 is equivalent to that of a classical stream cipher. In this paper it is shown that the claim is false in either the use of Y-00 for direct encryption or key generation, in all the parameter ranges it is supposed to operate including those of the experiments reported thus far. The security of Y-00 t...

For secure and high capacity optical fiber communications, WDM transmission experiment of 100-Gbit/s quantum stream cipher is demonstrated by Y-00 protocol with 64-level intensity modulation. Error-free transmission (bit-error rate < 10-9) in an 120-km amplifier repeated fiber link is successfully achieved.
متن کاملTowards Quantum Enigma Cipher
This research note suggests a new way to realize a high speed direct encryption based on quantum detection theory. The conventional cipher is designed by a mathematical algorithm and its security is evaluated by the complexity of the algorithm for cryptanalysis and ability of computers. This kind of cipher cannot exceed the Shannon limit of cryptography, and it can be decrypted with probability...
متن کاملSecurity Analysis of Generalized Confidentialmodulation for Quantum Communication
We propose a new evaluation method for‘generalized confidential modulation(GCM)’ for quantum communication. Confidential modulationrealizes a secret communication by using secret information for modulationand noise in a channel. Y-00 is one of the famous methods of GCM forquantum communication. The existing evaluation methods for GCM arebased on stream ciphers. They can estimate its analytical ...
