Abstract
The purposes of the present invention are to improve safety of data transmission and a data transfer rate and to reduce an increase in costs for the improvement. An encryption unit 111 of a transmission device 1 generates encrypted data that allow plain data thereof to be uniquely identified A segmentation unit 121 segments the encrypted data into two types of basal signal point number information on the basis of map data provided by a map management unit 122. A basal signal point number generation unit 113 generates basal signal point number information used as information to be transmitted, on the basis of a set of the two types of information, i.e. horizontal basal signal point number information and vertical basal signal point number information.
Claims6
An information processing device that transmits predetermined information, the information processing device comprising a hardware CPU, the hardware CPU being configured to:
- generate a predetermined information identifier capable of uniquely identifying the predetermined information;
- segment the predetermined information identifier into n types of identifiers, wherein n is an integer of 2 or more, based on a predetermined rule;
- and
- generate, based on a set of the n types of identifiers, information to be transmitted,
- wherein the predetermined information identifier is a ciphertext data generated based on a plaintext data,
- each of the segmented identifiers is assigned to a constellation point on an IQ plane representing a phase and an amplitude of an optical signal, and
- wherein the hardware CPU is further configured to, subsequent to assigning each of the segmented identifiers to the constellation point on the IQ plane, perform two-dimensional irregular mapping on the segmented identifiers by applying a first irregular mapping in a first direction and a second irregular mapping in a second direction different from the first direction.
