Data transfer method, communication system and storage medium |
摘要 |
In a communication system, a transmitter device encrypts variable-length data having a data length corresponding to a kind of information to be transferred or a communication capacity, using a natural random number, to produce a variable-length random number sequence. Then, the transmitter device performs an exclusive OR operation per bit between the variable-length random number sequence and the information to produce transfer information, and transmits the transfer information to a receiver device. The transmitter device further transmits the variable-length data and the natural random number in an encrypted manner to the receiver device. The receiver device reproduces the variable-length data and the natural random number transmitted in the encrypted manner, and then encrypts the variable-length data using the natural random number to produce a variable-length random number sequence which is identical with the foregoing variable-length random number sequence produced at the transmitter device. Then, the receiver device performs an exclusive OR operation per bit between the thus produced variable-length random number sequence and the received transfer information to reproduce the original information.
