Method for providing a broadcast encryption based home security system
View Patent ↗Provided is a method for providing a home or business security system that relies upon data encryption for both communication and the storage of content. The disclosed technology incorporates all the devices necessary for a comprehensive security system, including, but not limited to, controllers, monitors, alarms and communication media. The system may include an unlimited number of devices and, further, individual devices may be added and removed as needed. Users may define and change the boundaries of a security system or, in other words, decide what devices to include or not include in such a system. A defined boundary does not need to be confined to a single location. In one embodiment, the claimed subject matter incorporates xCP based broadcast encryption technology.
1. A method for providing security to a facility, comprising:
grouping a plurality of security components associated with physical assets of a facility into a cluster that binds the plurality of components into a secure configuration for the protection of the physical assets;
generating a message, wherein the message includes an encrypted message text, a key management block (KMB), and an encrypted title key (ETk);
transmitting the encrypted message text, the KMB and the ETk from a first component of the plurality of security components to a second component of the plurality of security components, wherein the transmitting of the encrypted message text, the KMB and the ETk is via a wireless protocol based upon xCP broadcast encryption;
decrypting the encrypted message text using the KMB and the ETk to produce a decrypted message, the decrypting the encrypted message text, comprising:
decrypting the ETk to generate a title key (Kt); and
decrypting the encrypted message text by using the Kt; and
executing a command transmitted in the decrypted message on the second component.
2. The method of claim 1 , wherein the physical assets comprise is a home.
3. The method of claim 1 , wherein the physical assets comprise a business.
4. The method of claim 1 , wherein the security components are selected from a list comprising:
a door alarm;
a window alarm;
a keypad.
5. The method of claim 1 , executing the command on the second component comprising deactivating an alarm.
6. The method of claim 1 , executing the command on the second component comprising activating an alarm.
7. A security system, comprising:
a plurality of security components associated with physical assets of a facility;
a cluster that binds the plurality of components into a secure configuration for the protection of the physical assets;
a plurality of messages, each message comprising:
an encrypted message text;
a key management block (KMB); and
an encrypted title key (ETk);
logic for transmitting the encrypted message text, the KMB and the ETk among the security components;
logic for decrypting the encrypted message text using the KMB and the Etk to produce a decrypted message text; and
logic for executing a command transmitted in the decrypted message on the second component.
8. The security system of claim 7 , wherein the transmission of the encrypted message text, the KMB and the ETk is via a wireless protocol based upon xCP broadcast encryption.
9. The security system of claim 7 , the logic for decrypting the encrypted message, comprising:
logic for decrypting the ETk to generate a title key (Kt); and
logic for decrypting the encrypted message text by using the Kt.
10. The security system of claim 7 , wherein the physical assets comprise a home.
11. The security system of claim 7 , wherein the physical assets comprise is a business.
12. The security system of claim 7 , wherein the security components are selected from a list comprising:
a door alarm;
a window alarm;
a keypad.
13. The security system of claim 7 , wherein a remote location is incorporated into the cluster.
14. The security system of claim 7 , executing the command on the component comprising deactivating an alarm.
15. A programming product for providing security to a facility, comprising:
a non-transitory memory; and
logic stored on the memory for execution on a processor, for:
grouping a plurality of security components associated with physical assets of a facility into a cluster that binds the plurality of components into a secure configuration for the protection of the physical assets;
generating a message, wherein the message includes an encrypted message text, a key management block (KMB), and an encrypted title key (ETk);
transmitting the encrypted message text, the KMB and the Etk from a first component of the plurality of security components to a second component of the plurality of security components, wherein the transmitting of the encrypted message text, the KMB and the ETk is via a wireless protocol based upon xCP broadcast encryption;
decrypting the encrypted message text using the KMB and the ETk to produce a decrypted message, the decrypting the encrypted message text, comprising:
decrypting the ETk to generate a title key (Kt); and
decrypting the encrypted message text by using the Kt; and
executing a command transmitted in the decrypted message on the second component.
16. The programming product of claim 15 , wherein the physical assets comprise a home.
17. The programming product of claim 15 , wherein the physical assets comprise a business.
18. The programming product of claim 15 , wherein the security components are selected from a list comprising:
a door alarm;
a window alarm;
a keypad.
19. The programming product of claim 15 , the logic for executing a command on the second component comprising logic for deactivating an alarm.
20. The programming product of claim 15 , the logic for executing a command on the second component comprising logic for activating an alarm.
