PROBLEM TO BE SOLVED: To provide a communication system for improving the confidentiality of communication. SOLUTION: Source data including at least either a message source or a home page source following an HTTP are transmitted and received. At a transmission side, a ciphertext is generated by encrypting at least a partial message in messages excluding a fixed message in the source data, and partial encrypted source data are generated by connecting the ciphertext to any source data other than this partial message, and the partial encrypted source data are transmitted. At a reception side, the partial encrypted source data are received, and the portion is decoded by decoding the ciphertext in the partial encrypted source data, and the partial encrypted source data other than this decoded portion are connected to this decoded portion, and the source data are reproduced.
