The invention discloses a key generation method based on bit error rate parameter self-adaptive adjustment and a client, and the method comprises the steps: carrying out the bit error rate measurementand quantification of a channel shared with an opposite end for multiple times in a parameter adjustment stage, and adjusting a bit error rate measurement / quantification parameter, so that the code forming rate of a quantization result of the bit error rate meets a preset requirement; and based on the adjusted parameters, performing bit error rate measurement on the channel, and quantifying the bit error rate obtained by measurement to obtain a consistent key. Compared with a physical layer key generation scheme based on polarization mode dispersion, an additional key distribution device andthe like do not need to be arranged, a line does not need to be transformed, the method is compatible with an existing information transmission system, and cost saving is facilitated; And in the process of producing the key based on the bit error rate of the channel, parameters can be adaptively adjusted according to different channel environments, so that the key utilization rate is improved, namely, a high-speed key and a consistent key which meet the requirements are generated.
Description
technical field [0001] The invention relates to the technical field of information security transmission, in particular to a key generation method based on adaptive adjustment of bit error rate parameters and a client. Background technique [0002] The rapid development of information networks, the popularization of "Internet +" applications and the rise of smart cities have changed traditional business forms and service models such as electricity, finance, telecommunications, transportation, energy, and urban gas supply, water supply, and heating. Facility assurance presents unprecedented security challenges. Stuxnet, Ukraine's power grid outage, and the Mirai worm that shut down a country's internet broadly demonstrate how attacks on critical infrastructure are evolving. [0003] The optical communication rate and distance have been greatly improved, and the openness of optical networks has been significantly enhanced. Existing optical communications cannot resist line o...
