| Abstract(in English) | In wiretap channel coding by Wyner,one can transmit messages to a legitimate receiver reliably without giving any information to eavesdroppers,if the legitimate channel is less noisy than those of eavesdroppers.Zhang proposed a recursive scheme with z-transformation to evaluate equivocation at the eavesdroppers,and constructed equivocation codes with codeword/message length below $(n,m)=(97,26)$ systematically.Following Zhang, Mori and Ogawa proposed an efficient method to evaluate security of coset codingwhen the legitimate channel is noiseless, and constructed codes with codeword/message length $(n,m)=(400,30)$.In this study, wiretap channel coding has been implemented by concatenating coset coding and the Reed-Solomon codes.Then, by evaluating bit error rates at the legitimate receiver and security against eavesdroppers,the range of valid parameters, such as transmission rates and random number rates, has been studied. |
