Intrusion detection and secure remote alarm communication system for a security system for the inactive storage of the active ingredients of weapons of mass destruction
First Claim
1. An intrusion detection and remote alarm communication system comprising:
- an intrusion detecting sensor, said sensor being capable of detecting the entry of an intruder into a space, said sensor communicating with a transmitter, said sensor sending a predetermined signal to said transmitter when an intruder is detected, said sensor in a location proximate to said transmitter,a transmitter, said transmitter transmitting a signal to a receiver, said signal having a first mode and a second mode, said first mode being a prearranged secret sequence of different messages known as the first set, said first mode indicating a normal secure condition, said second mode indicating that said sensor has sent said predetermined signal to said transmitter that an intruder has been detected, said second mode being the alarm mode,a receiver, located at a distance from said transmitter, said receiver having means for receiving said signal from said transmitter, said receiver having access to a second set of said prearranged secret sequence of different messages identical to said first set, said receiver having means for comparing said received sequence with said second set and recognizing that said received sequence corresponds with said second set and responding by indicating a normal secure condition, said receiver recognizing that said received sequence does not correspond with said second set and responding by indicating an alarm condition, said receiver recognizing an interruption in said signal and responding by indicating an alarm condition, said receiver recognizing said second mode and responding by indicating an alarm condition.

Abstract
A security system to create and maintain a secure communication link between a remote secure storage site and a law enforcement office using a continuous prearranged encrypted signal on the communication link. The authenticity of the encrypted signal is validated at the law enforcement office. Interruption of the encrypted signal is treated as an alarm that must be investigated. Sensors at the remote secure storage site detect intrusions and trigger the transmission of an alarm signal from the site to the law enforcement office on the communication link. The law enforcement office may enable video cameras or containment devices in the event of an intrusion.

14. An intrusion detection and remote alarm communication system comprising:
-
an intrusion detecting sensor, said sensor being capable of detecting the intrusion into a space in a first location, said sensor communicating with a first transmitter/receiver in said first location, said sensor sending a predetermined signal to said first transmitter/receiver when an intrusion is detected, said first transmitter/receiver in said first location communicating with a second transmitter/receiver in a second location, said communicating having a first mode and a second mode, said first mode receiving said stimulus message from said second transmitter/receiver, transforming said stimulus message using a secret prearranged method to yield a reply message, transmitting said reply message to said second transmitter/receiver, said first mode indicating that said space and the communication link is secure, said second mode indicating said sensor has sent said predetermined signal to said first transmitter/receiver that an intrusion has been detected, said first transmitter/receiver interrupting said first mode to transmit an alarm in said second mode, said second mode being an alarm mode, said second transmitter/receiver sending said stimulus message taken from a set of stimulus messages each having a correct reply message transformed from said stimulus message using said secret prearranged method, receiving said reply message from said first transmitter/receiver, comparing said reply message with said correct reply message, said second transmitter/receiver indicating a normal secure condition when said reply message is correct, said second transmitter/receiver indicating an alarm condition when said reply message is incorrect, said second transmitter/receiver indicating an alarm condition when there is no reply, said second transmitter/receiver recognizing said second mode and responding by indicating an alarm condition. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
