According to wiretap channel coding by Wyner, it is possible to encode messages (or secret keys) so that the legitimate receiver can obtain the messages without an error and the eavesdropper cannot obtain any information of the messages, when the noise difference of the communication channels is utilized. It is known theoretically that good codes can be generated by random coding with high probability when the code length n is large, though it is difficult to confirm whether thus generated codes are actually secure or not.
In this paper, we propose a numerical method to check whether linear equivocation codes are actually secure or not. Our method is based on the multivariate discrete Fourier transform and can be used even when the code length n is large. With the
code length n = 400 and the message length m = 30, we have verified the security of equivocation codes in a few minutes, and showed numerically that it is possible to generate equivocation codes which introduce high disturbance approaching theoretical limits against the eavesdropper. |
