Abstract: With the continuous development of computer technology in the field of industrial control and aerospace, the function of the epigynous machine software is increasingly perfect, and the parameter setting is more complicated. Macro configuration of parameters using the mode of the task macro reduces the complexity of the operation and improves reliability of parameter configuration. However, the task macro brings convenience to parameter setting of epigynous machine, but also faces unprecedented challenges. How to protect the security in the task macro become a hot topic of academic research. Based on this，firstly,we introduce an overview of the task macro, give the issues of data security. Moreover, we propose a scheme of task macro for data security based on SM3 and SM4. Lastly, the feasibility of the scheme has been proved by designing simulation system model.
