Quantum Hash function and its application to privacy amplification in quantum key distribution, pseudo-random number generation and image encryption.

摘要: Quantum information and quantum computation have achieved a huge success during the last years. In this paper, we investigate capability of Hash function, which can be constructed by subtly modifying walks, famous model. It is found that function act as hash for privacy amplification process key distribution systems with higher security. As byproduct, also used pseudo-random number generation due to its inherent chaotic dynamics. Further discuss application image encryption propose novel algorithm. Numerical simulations performance comparisons show eligible in distribution, terms various tests randomness tests. extends scope information.
