Abstract

A system and methods for secure communication are disclosed. A network packet comprising encrypted network address comprising an unencrypted network address encrypted by a first GPS time and a first pseudo random number is received. The encrypted network address is decrypted using the first GPS time and the first pseudo random number to provide the unencrypted network address. The network packet is transmitted based on the unencrypted network address.

Claims

1. A method for secure communication, the method comprising:

receiving by action of a processor a network packet comprising an encrypted network address comprising an unencrypted network address encrypted by a first GPS time and a first pseudo random number;

decrypting by action of the processor the encrypted network address using the first GPS time and the first pseudo random number to provide the unencrypted network address;

transmitting by action of the processor the network packet based on the unencrypted network address;

calculating by action of the processor a next stage network address for the network packet through a closed commercial network; and

encrypting by action of the processor the next stage network address using a second GPS time and a second pseudo random number to provide the encrypted network address.

2. The method of claim 1, further comprising transmitting by an action of the processor the network packet through a closed commercial network.

3. The method of claim 2, wherein the closed commercial network comprises at least one of:

an internet protocol network, a circuit-switched network, a packet-switched network, and a wireless communication network.

4. The method of claim 1, wherein the second GPS time is the first GPS time, and the second pseudo random number is the first pseudo random number.

5. The method of claim 1, wherein the second GPS time is different from the first GPS time, and the second pseudo random number is different from the first pseudo random number.

6. The method of claim 1, wherein the network packet further comprises encrypted data.

7. A system for secure communication, the system comprising:

a processor;

a receiver module operable to receive a network packet comprising an encrypted network address comprising an unencrypted network address encrypted by a first GPS time and a first pseudo random number;

a decryption module operable to decrypt by action of the processor the encrypted network address to provide the unencrypted network address;

a transmitter module operable to transmit the network packet based on the unencrypted network address; and

an encryption module operable to;

calculate by action of the processor a next stage network address for the network packet through a closed commercial network; and

encrypt by action of the processor the next stage network address using a second GPS time and a second pseudo random number to provide the encrypted network address.

8. The system of claim 7, wherein the system comprises a mobile communication device.

9. The system of claim 7, wherein the transmitter module is further operable to transmit the network packet through a closed commercial network.

10. The system of claim 9, wherein the closed commercial network comprises at least one of:

an internet protocol network, a circuit-switched network, a packet-switched network, and a wireless communication network.

11. The system of claim 7, wherein the second GPS time is the first GPS time, and the second pseudo random number is the first pseudo random number.

12. The system of claim 7, wherein the second GPS time is different from the first GPS time, and the second pseudo random number is different from the first pseudo random number.

13. A non-transitory computer readable storage medium comprising computer-executable instructions for performing a method for secure communication, the method executed by the computer-executable instructions comprising:

receiving a network packet comprising an encrypted network address comprising an unencrypted network address encrypted by a first GPS time and a first pseudo random number;

decrypting the encrypted network address using the first GPS time and the first pseudo random number to provide the unencrypted network address;

transmitting the network packet based on the unencrypted network address;

calculating a next stage network address for the network packet through a closed commercial network; and

encrypting the next stage network address using a second GPS time and a second pseudo random number to provide the encrypted network address.

14. The non-transitory computer readable storage medium of claim 13, the method executed by the computer-executable instructions further comprising transmitting the network packet through a closed commercial network.

15. The non-transitory computer readable storage medium of claim 14, wherein the closed commercial network comprises at least one of:

an internet protocol network, a circuit-switched network, a packet-switched network, and a wireless communication network.

16. The non-transitory computer readable storage medium of claim 13, wherein the second GPS time is the first GPS time, and the second pseudo random number is the first pseudo random number.

17. The non-transitory computer readable storage medium of claim 13, wherein the second GPS time is different from the first GPS time, and the second pseudo random number is different from the first pseudo random number.
