《GB/T 39404-2020工业机器人控制单元的信息安全通用要求》由TC591（全国机器人标准化技术委员会）归口，主管部门为中国机械工业联合会。
Introduction
Interpretation of the core content of the standard
GB/T39404-2020 is my country's first national information security standard specifically for industrial robot control units. It has built a complete security framework from three dimensions: physical security, communication security, and system protection.
Key Technical Requirements
| Security Dimension | Basic Requirements (SR) | Enhanced Requirements (RE) |
|---|---|---|
| Audit Requirements | Event Logging, Storage Protection | Central Audit Trail, One-Time Write Media |
| Integrity Protection | Communication Verification, Input Verification | Cryptographic Protection, Automatic Alarm |
| Confidentiality Control | Information Encryption, Password Management | Regional Boundary Protection, Memory Clearing |
Typical Application Scenarios
In the automobile welding robot system, the standard requires:
- Two-way authentication is required between the teach pendant and the controller
- Motion control command transmission must use AES-256 encryption
- System logs should retain at least 90 days of audit records
Implementation suggestions
Enterprises should implement in stages:
- Design stage: Establish a communication integrity protection mechanism in accordance with clause 6.3.2 of the standard
- Production stage: Solidify the equipment identity according to the requirements of 6.5.1
- Operation and maintenance stage: Implement a central audit system in accordance with 6.3.1
Technology evolution analysis
This standard innovatively combines Industrial robot control safety requirements are refined as follows:
- For the first time, the safety boundary of the control unit (CU) is clarified
- A three-level protection system of main control-CU-servo drive is established
- Introduction of industrial characteristic indicators such as time synchronization accuracy (6.3.4.4)
