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
Navigate to Power control > Controller operation.
Select the
Extended settings. A message will appear. Select SECP521R1.
The encryption algorithm will be changed and can be used without rebooting.
