Abstract

The invention provides an encryption method and system of a geological survey instrument based on a chaos sequence. The encryption system comprises a seed key pool arranged at an encryption end, wherein the seed key pool consists of a pre-set number of 32bits seed keys and is numbered. The encryption method comprises the following steps: randomly selecting a plurality of seed keys from the seed key pool during encryption; sending the selected seed keys into an extension coupling integer tent to generate a key sequence by mapping; and encrypting pre-set data. According to the encryption method and the encryption system provided by the invention, the calculation difficulty of chaos mapping and consumption are reduced through an integer method, so that the requirements on the power consumption of the geological survey instrument and ground disaster monitoring equipment can be met, and the excellent security property can be realized through expansion and coupling. Furthermore, the load calculation such as a division method and a power method can be avoided in the process; the requirement on the calculation capacities of hardware is low, so that the encryption method and the encryption system are applicable to the existing geological survey instrument and ground disaster monitoring equipment without redesign and redevelopment of the existing equipment.

Description

technical field [0001] The invention relates to an encryption method and system of a geological survey instrument based on a chaotic sequence, belonging to the technical fields of geological survey, network communication and information security. Background technique [0002] With the advancement of geological survey technology, relevant instruments and equipment suitable for geological survey have developed rapidly, and a large number of professional geological survey instruments and disaster monitoring have emerged with the advantages of low power consumption, automation, real-time monitoring, and unattended. Early warning equipment and data platform software with powerful functions such as 2D / 3D graphic display, comprehensive data processing, and multi-parameter call calculation. Geological survey instruments and disaster monitoring equipment are mostly deployed in relatively remote mountains, canyons, and jungle areas, and their data transmission mainly uses public netwo...
