●
Security statistics
Specifies whether the statistics of security events are sent to the master. Security events
are authentication requests of the master to the station module. If this option is activated,
all authentication requests are stored in the station module with date, time and result and
sent to the master for further evaluation.
Range of values:
–
Do not send security statistics
–
Send security statistics
Default setting: Do not send security statistics
●
SHA-1 interlock
Setting to select whether the module may use the secure hash algorithm SHA-1 if "SHA-
256" was configured as the Secure hash algorithm and the master does not support SHA-
256.
Range of values:
–
SHA-1 mode not allowed
The module must not use SHA-1. If the master does not support SHA-256, no
connection will be established.
–
SHA-1 mode allowed
The module can use SHA-1 if the master does not support SHA-256.
Default setting: SHA-1 mode not allowed
●
Secure hash algorithm (SHA)
Selection of the Secure Hash Algorithm (SHA)
Range of values:
–
SHA-1
–
SHA-256
Default setting: 256
●
Key wrap algorithm
Selection of the Advanced Encryption Standard (AES)
Range of values:
–
AES-128
–
AES-256
Default setting: AES-128
●
Key length
Specifies the length of the pre-shared key in bytes.
The following lengths are used depending on the key wrap algorithm.
–
For AES-128: 16 bytes
–
For AES-256: 32 bytes
