The Security Tab

The properties on the Security tab control crucial aspects of the security of the Datacryptor

unit.

They are as follows:

• KEK: the longest time that the unit will use a KEK for, in days, hours, minutes.

• DEK: the longest time that the unit will use a DEK for, in days, hours, minutes – or the

time at which to perform a daily key exchange (see next control).

• Time of Day Key Exchange: check this box to force a regular key exchange at the

same time every day (as specified by the DEK field).

• Change KEK with DEK: check this box to change the KEK when the DEK changes. When

this is checked the KEKs are not stored and will not be visible in the Key Management

dialog.
