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.
