SSL

TLS Standard

The device is compatible with TLS v1.1 to TLS v1.3 standards, but due to lack of secur-
ity, SSL v3.0, TLS 1.0, and RC4, MD5, SHA1, and DES encryption are disabled. All
ciphers use Diffie-Hellman key exchange (Perfect Forward Secrecy).

TLS 1.3 performance

The interaction of TLS 1.3 and unsecure certificates and a web browser with Chromium
Engine (Google Chrome or MS Edge) can lead to performance losses and thus longer
loading times. In this constellation, the Chromium Engine does not correctly support the
SSL Session Cache (Session Tickets) and the math unit of the embedded CPU may be
overwhelmed with continuous RSA operations. Possible workaround:
