Board Security Feature

A security feature is incorporated in all MultiCam-compliant boards.

The general idea is that the OEM application programmer is able to engrave in the board a secret proprietary key.

The security key is an 8-bytes string of ASCII characters. Any character is allowed. A null character acts as the termination character of the key.

The security key is stored in the non-volatile memory of the board and cannot be read back.

There is no way to obtain this security key number back from the board. However, it is possible to verify that a given board currently holds a security key equal to a given one.

Using this simple mechanism, it is easy to lock an application to a board or to a set of boards.
