摘　　要：当前工业网络输出指令加密机制多为目标式和独立式,导致指令安全控制效果不理想,丢包率增加,为此提出基于区块链隐私保护的工业网络输出指令安全控制算法。设计工业网络指令安全控制辨识目标,将此目标导入初始的安全指令控制加密程序中,设置一个基础的控制指令。以其作为引导,进行安全控制目标的扩展及生成,对指令的内容进行多层级加密。在指令加密处理的基础上,根据输出指令安全控制指标及参数的限制,设计不同的安全控制标准和双向控制条件,将安全控制辨识目标导入当前的区块链双向控制结构中,形成一个具体细化的控制结构。在控制结构中,利用区块链技术将区块控制程序与重叠指令的控制程序关联起来,实现动态化的指令输出安全控制。实验结果表明:这种安全控制算法能够对全部工业网络输出指令数据进行加密处理,能够最大程度上保证工业网络输出指令隐私安全,丢包率在5.2%以下,控制正确率较高,具有较高的实际应用价值。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 industrial network instruction security control identification target,import this target into the initial security instruction control encryption 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 bidirectional 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 security control.The experimental results show that this security control algorithm can encrypt all output instruction data of industrial networks,ensuring the privacy and security of industrial network output instructions to the greatest extent.The packet loss rate is below 5.2%,and the control accuracy is high,which has high practical application value.
