Certificates for master/slave communication

Last modified:


Starting with firmware 30.2.7, the blue’Log provides a new option for creating certificates when setting the blue’Log to master/slave mode. This option is based on the elliptic curves certification method (521-bit encryption), which increases security and speeds up certificate creation.

SECP521R1 is widely used in cryptographic protocols and applications, particularly in environments requiring high security for communication.


❗

Cybersecurity warning

  • Existing blue’Logs use RSA 4096. We recommend updating to the elliptic curves method.

  • The elliptic curves method is applied to all newly commissioned blue’Logs.

Change the certification method manually

Prerequisites

  • blue’Log XC uses master-slave communication

  • Firmware 30.2.7 or higher for master and slave devices

  • blue’Logs are in the same network


Steps

  1. Navigate to Power control > Controller operation.

  2. Select the image-20240829-120549.png Extended settings.

  3. A message will appear. Select SECP521R1.

  4. The encryption algorithm will be changed and can be used without rebooting.
