System Security
Two distinct areas are designed to insure that encrypted
content is controlled. Once the Cavity (enclosure) has been
opened, encrypted content cannot be played also after
closing until the Cavity Security System (CSS) has been
initialized by a trusted user.
The other area insures that the secure system clock
governing playback of content cannot be reset to allow
encrypted content by simply changing the system time to
fall within the playable window contained in the
decryption key (KDM). Occasionally, the system (secure)
clock must be reset to compensate for variations. This task
can be done by a trusted user.
Security Initialize
When the security of the Auditorium Unit has been
breached or a tamper switch failure is detected,
presentation is halted and cannot be resumed until Security
has been initialized. The STATUS Alert is set RED, the
MESSAGE Alert is set RED, and a Security Alert Message
is generated and written to the Alert Message Log.
