Ensuring the security of computer control system interfaces can be achieved through measures such as interface authentication, data encryption, current limiting control, parameter verification, and interface monitoring.

1. Interface authentication: By using tokens, sessions or other authentication mechanisms, ensure that only authorized users can access the system interface. OAuth, JWT and other technologies can be used to implement interface authentication.

2. Data encryption: For sensitive data, it should be encrypted during transmission and storage to prevent the data from being intercepted or stolen by hackers. You can use protocols such as SSL/TLS to ensure encrypted data transmission, or you can use Encryption algorithms to protect data storage.

3. Current-limiting control: By limiting the request rate of each user or IP address, you can avoid interface service crashes due to malicious attacks or abnormal requests. You can use tools such as API gateways to implement current-limiting control.

4. Parameter verification: When accepting user input or external requests, parameters must be strictly verified to prevent malicious attacks or illegal input. Regular expressions, parameter filtering and other technologies can be used to prevent malicious attacks or illegal input. Implement parameter verification.

5. Interface monitoring: It is necessary to monitor the performance and stability of the interface to discover and solve potential problems in a timely manner. You can use monitoring tools such as Zabbix, Grafana, etc. to implement interface monitoring.

Commonly used encryption algorithms in data encryption

1. Symmetric encryption algorithm: also known as single-key encryption algorithm, that is, the same key is used for encryption and decryption. Common symmetric encryption Algorithms include AES, DES, 3DES, RSA, etc.

2. Asymmetric encryption algorithm: also known as public key encryption algorithm, that is, encryption and decryption use different keys, one public key is used for encryption, and one private key is used for decryption. Common asymmetric Encryption algorithms include RSA, ECC (elliptic curve encryption algorithm), Diffie-Hellman, etc.

3. Hash algorithm: Also called hash algorithm, it is an algorithm that maps data of any length into a fixed-length string. Common hash algorithms include SHA-256, SHA- 3 etc.

4. Message authentication code algorithm: also called MAC algorithm, it is an algorithm that uses keys and data to calculate a fixed-length string. It is used to verify the integrity and authenticity of data. Common MAC algorithms include HMAC, CMAC, etc.
