Abstract(in English) | In the wireless communication, secret key agreement schemes on physical layer attracts attentions for protecting communications from eavesdropping. Most of secret key agreement schemes generate keys by scalar quantization. However, secret keys generated by scalar quantization occur key disagreement in higher probability than these by vector quantization. A general quantizer selection scheme selects a quantizer with minimum key disagreement between two authorized stations. An eaves-dropper is able to generate keys with this quantizer more easily. This paper assumed correlated MIMO channel, and proposed the quantizer utilizing correlation between authorized stations as key information and the quantizer selection scheme taking key entropies leak to eavesdroppers into consideration. This scheme that reduces information leaks to eavesdropper maintaining key disagreement probability between authorized stations. |
