Abstract: PURPOSE: A data encoding method is provided to encode data efficiently in view of stability such as a data security and a subscriber authentication, to carry out a high speed of operation, and to allow to apply in a radio communication environment. CONSTITUTION: In a data encoding method of a radio communication environment, messages are input, and the messages are divided into two and the divided messages are input to a left block and a right block respectively. A bit stream input to the right block is input to an F function and the left block of the next round. After a bit exclusive OR operation of the bit stream in which the F function is input to the bit stream of the right block and the bit stream input to the left block is carried out, the result values are input to the right block of the next round. After the above operations are carried out repeatedly by a described times, the result values are transposed and the finally encoded stream is output.
