| Abstract(in English) | As an information security technology for wireless communications, a secret key agreement system exploiting ESPAR antenna was proposed. In this paper, we make a prototype of secret key generator of two nodes both loaded with 3-element ESPAR antenna and perform fundamental experiment. First, we evaluate the prototype from the viewpoint of FBR(Front to Back Ratio). We establish a formula that converts measured varactor control voltage into simulated reactance. The varactor control voltage ranging 0～5V can be converted the reactance ranging 70～-68Ω by this formula. Secondly, we evaluate bit agreement rate of generated key vs FBR and vs SCC(Space Cross Correlation) of the antenna directivity. As a result, bit agreement rate is higher than 0.8 when SCC is lower than 0.7 or FBR is higher than 4dB. |
