System Security; Security Initialize; Set Time Source For Sms Server - Sony LMT-300 User Manual

System Security

Two distinct areas are designed to insure that access to
encrypted content is controlled. Once area insures that
once the Cavity (enclosure) has been opened encrypted
content cannot be played 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.

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.
