using the Secure Update utility or some custom utility (to update the distrib-
utor key count).
Using the request code, an update code, or a license addition code is gener-
ated under the
Key Activator tab of the Toolkit.
Response Data
The scrambled result derived when the Sentinel Key processes the query
data using the AES algorithm. The Sentinel Key returns the response data to
the application. The application then uses the response to determine
whether the user is authorized to run the application.
S
Secret Key
A secret key generally refers to the key in a secret key cryptography system,
in which both sides use the same key. It may also refer to the private key in a
public key cryptography system, because the private key must also be kept
"secret."
The AES feature uses a 128-bit long secret key to encrypt/decrypt data.
Secure Communication Tunnel
An end-to-end secured session between the client and the Sentinel Key for
providing secure private communication. The communication packets are
encrypted using the AES algorithm, for which the session key is generated
using ECC-based key exchange (ECKAS-DH1).
Secure Update Utility
The Secure Update utility is used for updating the Sentinel Keys and distrib-
utor keys remotely. It provides an alternative to the Secure Update Wizard.
