In this paper, we propose the new FEC(Forward Error Correction) code method, so called RCNC(Random Connection Node Convolutional) code with security property. Recently, many wireless communication systems, which can prouide integrated semices of various media types and hil rales, are required to haue the ability of secreting information and error correclion. This code system is a kind qf conuolulional code, but it Ius various code formats as each node is connected differently. And systems hy using RCNC codes haue all. ability of error correction as well as information protection. We describe the principle of operating RCNC codes, including operation examples. In this paper, we also show the peiformance of BER(Bit Error Rate) and verify authority of network system with computer simulation.
