Page 58: Encryption
PKI Structure and Certificate Requirements The PKI structure is identical on all participating devices/systems: • Each EtherCAN/3-FD device or host system must have its own certificate and private key. • To establish a secure connection, both communication partners must store the trusted certificate of the other device. -
Page 59: Pki Configuration On The Ethercan/3-Fd
Steps to Establish a Secure Connection: 1. Install a valid PKI on the host system (see next subsection). 2. If neither the EtherCAN/3-FD nor the host system has trusted certificates configured, a connection can still be established. 3. However, without trusted certificates, an unauthorized third party could establish its own connection and access the same information. -
