Configurations

Anonymous

For module configuration, see Section 2.4.1 and Figure 5.

One-way authentication

For module configuration, see Section 2.4.2 and Figure 6. In

particular notice that:

– Module reference time must be initialized

– Root CA certificate and domain name of the server must be

loaded.

– Authentication ciphers: ECDSA with all EC curves, RSA-1024

and RSA-2048.

– Maximum allowed size for files uploaded to module is

approximately 1.3KB.

Mutual authentication

For module configuration, see Section 2.4.3 and Figure 7. In

particular:

– Module reference time must be initialized

– Root CA certificate and domain name of the server, client

certificate and client key files must be loaded.

– Authentication ciphers: ECDSA with all EC curves.

– Maximum allowed size for files uploaded to module is

approximately 3KB overall.
