Abstract

A method and related secure communications system. The method includes detecting, by a base station, a mobile device docked with the base station and in response to the detecting, generating at least one encryption key in the base station. The method also includes transmitting the encryption key to the mobile station by the base station while the mobile device is docked with the base station. The method also includes communicating encrypted data with the mobile station, the encrypted data corresponding to the encryption key.

Claims

1. A method, comprising:

detecting, by a base station, a mobile device docked with the base station;

in response to the detecting, generating at least one encryption key in the base station;

transmitting the encryption key to the mobile station by the base station while the mobile device is docked with the base station; and

communicating encrypted data with the mobile station, the encrypted data corresponding to the encryption key.

2. The method of claim 1, further comprising storing a second encryption key in the base station.

3. The method of claim 2, further comprising receiving second encrypted data from the mobile station and decrypting the second encrypted data using the second encryption key.

4. The method of claim 1, further comprising encrypting data, in the base station, that can be decrypted using the encryption key.

5. The method of claim 1, further comprising storing the encryption key in the mobile device.

6. The method of claim 1, wherein generating at least one encryption key includes generating at least one asymmetric encryption key pair.

7. The method of claim 1, further comprising storing a device ID corresponding to the mobile device.

8. The method of claim 1, wherein the generating and transmitting steps are repeated whenever the mobile device is re-docked in the base station.

9. The method of claim 1, further comprising transmitting a device ID and at least one encryption key to a server system.

10. The method of claim 1, further retrieving the encryption key from the server system by a receiver station.

11. A secure communications system comprising a base station and a mobile station, the base station configured to perform the steps of:

detecting a mobile device docked with the base station;

in response to the detecting, generating at least one encryption key using a controller;

transmitting the encryption key to the mobile station by the base station while the mobile device is docked with the base station; and

communicating encrypted data with the mobile station, the encrypted data corresponding to the encryption key.

12. The secure communications system of claim 11, the base station further configured to store a second encryption key in a memory in the base station.

13. The secure communications system of claim 12, the base station further configured to receive second encrypted data from the mobile station and decrypt the second encrypted data using the second encryption key.

14. The secure communications system of claim 11, the base station further configured to encrypt data that can be decrypted using the encryption key.

15. The secure communications system of claim 11, the mobile device configured to store the encryption key in the mobile device.

16. The secure communications system of claim 11, wherein generating at least one encryption key includes generating at least one asymmetric encryption key pair.

17. The secure communications system of claim 11, the base station further configured to store a device ID corresponding to the mobile device.

18. The secure communications system of claim 11, wherein the base station is configured to repeat the generating and transmitting steps whenever the mobile device is re-docked in the base station.

19. The secure communications system of claim 11, the base station further configured to transmit a device ID and at least one encryption key to a server system.

20. The secure communications system of claim 11, further comprising a receiver station configured to retrieve the encryption key from the server system.
