Abstract

Wireless communication is a convenient but not secure transmission media. For internet application, such as E-commerce, there are a lot of private information existed. To protect the secret information inside and to set up a secure communication becomes an urgent topic. The purpose of a perfect communication system is to ensure the authentic destination could correctly and successfully receive the exact desired information from the transmitter. Also, the system with authorization and authentication could protect the transmitted information away from the eavesdroppers. Generally, the encryption scheme is applied to. Although these methods have been employed in the system for the security, those unexpected and advanced attackers have been continuously developing. Error-free cryptogram based on Shannon’s theorem could provide a solution for the information security. It could be implemented with physical-layer security coding scheme. In this paper, the cypher generator is proposed with physical-layer coding scheme. The cypher format includes two parts. One is the prefixed code and the other is error-control code. The major purpose of prefixed code is the key to find the position indexing of code in the cypher. In this cypher generator, the interleaver plays a role to disturb the original data. It increases the degree of difficulty to break the cypher. With cryptanalysis, the practical example of LDPC is given. With AI technology, the advanced algorithm might be developed for cypher coding and decoding.
