摘要
The present disclosure provides a vector quantization based secret key generation device and method. The vector quantization based secret key generation device includes: a channel estimator for estimating a channel based on received signals to generate an estimated channel vector; a channel decorrelator for decorrelating entries of the estimated channel vector to generate a decorrelated estimated channel vector; a plurality of clustered vector quantizers (CVQs) each for quantizing the decorrelated estimated channel vector into a secret key or a secret key index; and a selector for selecting an optimal quantizer output from the plurality of CVQs and determining whether to discard the decorrelated estimated channel vector to reduce key disagreement probability (KDP). Therefore, the present disclosure provides a secret key generation technique that is capable of increasing key entropy and reducing KDP.
