Security Control Algorithm Design of Industrial Network Output Instruction Based on Blockchain Privacy Protection
At present,the encryption mechanisms for output instructions in industrial networks are mostly target based and independent,resulting in unsatisfactory command security control effects and increased packet loss rates.Therefore,a blockchain privacy protection based industrial network output instruction security control algorithm is proposed.Design an in-dustrial network instruction security control identification target,import this target into the initial security instruction control en-cryption program,and set a basic control instruction.Using it as a guide,expand and generate security control objectives,and encrypt the content of instructions at multiple levels.On the basis of instruction encryption processing,different security control standards and bidirectional control conditions are designed according to the limitations of output instruction security control indicators and parameters.The security control identification target is imported into the current blockchain bidirection-al control structure,forming a specific and refined control structure.In the control structure,blockchain technology is used to associate block control programs with overlapping instruction control programs,achieving dynamic instruction output se-curity control.The experimental results show that this security control algorithm can encrypt all output instruction data of in-dustrial networks,ensuring the privacy and security of industrial network output instructions to the greatest extent.The pack-et loss rate is below 5.2%,and the control accuracy is high,which has high practical application value.
