    摘要： An inventive wireless communication apparatus that, in a wireless communication system to which a secret key scheme is applied, can generate a secret key, which is different from a secret key generated by another party, even if a wireless signal is intercepted by the third part having an approximate propagation path environment to a receiving wireless communication apparatus. In the inventive apparatus, an eigenvalue selecting part (317) of a secret key generating part (207) selects a maximum one of MIMO channel eigenvalues received from an eigenvalue detecting part (206) and inputs the selected maximum eigenvalue to a quantizing part (327). The quantizing part (327) quantizes the magnitude of the maximum eigenvalue received from the eigenvalue selecting part (317) to produce and input a quantized data to a key generating part (337). The key generating part (337) uses a predetermined scheme to generate a secret key from the quantized data received from the quantizing part (327), and inputs the generated secret key to a control part or the like not shown.
