| Outline of Final Research Achievements |
We studied aspects of physical layer security in which noise on communication channels is exploited as resource for secrecy. Our focus is on secret key agreement with public discussion, and we analyzed the probability that two parties fail to agree on a common information. This problem is formulated as coding for ordered random variables with side information at the decoder, and statistical property of the associated signal sequence needs to be considered. Our analyses successfully predict the performance of the coding scheme. Construction of linear codes and quantization used in this protocol are also investigated.
