Abstract

The invention relates to a communication device of stroboscopic information. The communication device at least comprises an optical signal transmitting-receiving unit, an optical signal processing unit and an optical communication network; the first optical signal processing unit divides a light emission period into at least two light emission stages of light change according to at least two feature curves, wherein the feature curve of at least one light emission stage changes via a mode of being level off to zero candela; the first optical signal transmitting-receiving unit transmits an optical signal which carries preset information directly or through the optical communication network based on the stagewise curves of the light emission period sent by the optical signal processing unit;and the second optical signal processing unit performs safety verification based on the feature curve of the first light emission stage in the light emission period, which is received by the second optical signal transmitting-receiving unit, and obtains transmission information via a preset information conversion mode based on the feature curve of the second light emission stage when the safety verification passes. Encryption is carried out through optical parameters in multiple dimensions at different stages of the light emission period, and the degree of safety is relatively high.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication method and a communication device for stroboscopic information. Background technique [0002] The security measures of the existing optical communication system still adopt stream cipher encryption and decryption technology based on electrical signal processing. Due to the limitation of electronic "bottleneck", the encryption and decryption rate is low, and the maximum rate in the laboratory is only 2.5Gbit / s . When an emergency occurs, the business volume of the existing optical communication network may increase by dozens or even hundreds of times. The traditional encryption and decryption technology based on electrical signal processing is difficult It is fully compatible with the next-generation all-optical communication network, and the rate of encryption and decryption technology based on all-optical signal processing can exceed 100Gbit / s. At the same time, the e...
