采用k均值聚类的物理层密钥生成方案
Method for Secret key generation using k-means clustering
摘要
Abstract
Due to the fact that traditional key generation algorithms cannot make full use of the channel information,a key generation method based on k-means clustering is proposed.By using this method,both phase information and amplitude information can be fully utilized,and the consistency of the key can be improved effectively.In the key generation process,the two sides can classify the measured values by transferring the location of the cluster center,and will not cause leakage of key information.In order to improve the performance further,an improved method named k-means two dimensional compensation is proposed which combines the random pilot and two-dimensional compensation.Simulation result shows, compared with other key generation methods,the two schemes proposed in this paper can effectively improve the consistency and randomness of the secret key.关键词
