4 System Security
The LA GARD safe lock System implements various methods to enhance security. Security measures include encryption
of information when transmitted, when the data is at rest and devices authenticating each other.
4.1 Data Encryption
Encryption is used between entities that exchange information.
The encryption used will prevent an attacker from knowledge of the information exchanged between the communicating
partners and prevent replay attacks.
The entities that can communicate with each other include:
1. Software Application and the Keypad.
2. The Keypad and lock(s) via Multiplexer or not.
3. Key Fob and Keypad.
Types of information that will be encrypted include all combinations, configuration data and firmware used to update the
lock and Keypad.
4.2 Initial Combination Handling
Users are required to change their combination on the first use. This requirement will be enforced by the lock firmware.
Entries with a Display will show options for the user to change their combination. If, via the display, the authentication
attempt was for opening a lock, the opening sequence will be aborted and the change combination activity will be the
action until finished or aborted. The opening sequence would need to be restarted.
Non-Display entries will indicate an error and a # command can be used by the User to change their combination. See
Appendix A for the syntax of the # Commands. The failed error will be 3 red LED blinks and 3 low beeps.
The firmware will enforce this requirement whenever the user is added, or the User’s combination is reset. This
requirement does not apply to the Master user and combination.
