HRVQ:A High-Speed Random Key Extraction Sche me Based on Vector Quantization
摘要
Abstract
To solve the dilemma that a high bit generation rate and a low probability of bit disagreement can′t be a-chieved simultaneously in current physical layer key extraction schemes,a high-speed random key extraction scheme based on vector quantization (HRVQ)which just employs the RSS of Wi-Fi signal is proposed.First,the inconsistent RSS meas-urements between the two communication parties were reduced by inconsistency removal to achieve low bit disagreement rate.Then,the vector quantization was introduced to accelerate the extraction of bit streams from channel information and a-chieve high bit generation rate.Last,fuzzy extractor was employed to achieve adequate randomness and zero bit disagreement rate.The result of experiments indicates that our scheme outperforming the best scheme of the state-of-the-art can reach a 284% bit generation rate with a zero bit disagreement rate and a guaranteed randomness.关键词
