Abstract

APARELHO DE COMUNICAçãO SEM FIO E MéTODO DE COMUNICAçãO SEM FIO. A presente invenção refere-se a um aparelho de comunicação sem fio da invenção que, em um sistema de comunicação sem fio junto ao qual um esquema de chave secreta é utilizado, pode gerar uma chave secreta, a qual é diferente de uma chave secreta gerada por outra parte, mesmo se um sinal sem fio for interceptado pela terceira parte possuindo um ambiente de caminho de propagação assemelhado para um aparelho de comunicação sem fio que recebe. No aparelho da invenção, uma parte de seleção de autovalor (317) de uma parte de geração de chave secreta (207) seleciona um autovalor máximo dos autovalores de canal MIMO recebidos a partir de uma parte de detecção de autovalor (206) e informa o autovalor máximo selecionado para uma parte de quantização (327). A parte de quantização (327) quantiza a magnitude do autovalor máximo recebido a partir da parte de seleção de autovalor (317) para produzir e informar dados quantizados para uma parte de geração de chave (337). A parte de geração de chave (337) utiliza um esquema predeterminado para gerar uma chave secreta a partir dos dados quantizados recebidos a partir da parte de quantização (327), e informa a chave secreta gerada para uma parte de controle ou coisa parecida não apresentada.
