Secure end-to-end transport through intermediary nodes
A communication network encrypts a first portion of a transaction associated with point-to-point communications using a point-to-point encryption key. A second portion of the transaction associated with end-to-end communications is encrypted using an end-to-end encryption key.
1. A method implemented on a first computer, the method comprising:
encrypting first data of a first data path in a transaction using a first security association, wherein:
the first data path is through an intermediary server that provides connectivity between the first computer and a second computer; and
the transaction comprises a transaction message that includes control data and payload data;
transmitting the control data to the intermediary server, wherein:
the control data includes a token associated with the intermediary server;
the token provides transaction routing information;
the second computer receives the first data from the intermediary server; and
the first data is decrypted;
encrypting second data of a second data path using a second security association, wherein the second data path is distinct from the intermediary server;
and
transmitting the payload data through the second data path.
2. The method of claim 1 , wherein the token is issued by the intermediary server.
3. The method of claim 1 , wherein the first computer is a first mobile device.
4. The method of claim 3 , wherein the first mobile device and the intermediary server are coupled over a mobile network.
5. The method of claim 4 , wherein the mobile network provides an Internet protocol (IP) infrastructure of a wireless service provider.
6. The method of claim 4 , wherein the first mobile device is a source for the transaction and the second computer is a target for the transaction.
7. The method of claim 6 , wherein the transaction message includes a device identification associated with the second computer.
8. The method of claim 7 , wherein the transaction message is modified by the first computer based on the device identification.
9. The method of claim 8 , wherein the device identification is associated within the intermediary server to a third security association between the intermediary server and the second computer.
10. The method of claim 4 , wherein the second computer is a personal computer.
11. A first computer having a processor configured for:
encrypting first data of a first data path in a transaction using a first security association, wherein:
the first data path is through an intermediary server that provides connectivity between the first computer and a second computer; and
the transaction comprises a transaction message that includes control data and payload data;
transmitting the control data to the intermediary server, wherein:
the control data includes a token associated with the intermediary server;
the token provides transaction routing information;
the second computer receives the first data from the intermediary server; and
the first data is decrypted;
encrypting second data of a second data path using a second security association, wherein the second data path is distinct from the intermediary server;
and
transmitting the payload data through the second data path.
12. The first computer of claim 11 , wherein the token is issued by the intermediary server.
13. The first computer of claim 11 , wherein the first computer is a first mobile device.
14. The first computer of claim 13 , wherein the first mobile device and the intermediary server are coupled over a mobile network.
15. The first computer of claim 14 , wherein the mobile network provides an Internet protocol (IP) infrastructure of a wireless service provider.
16. The first computer of claim 14 , wherein the first mobile device is a source for the transaction and the second computer is a target for the transaction.
17. The first computer of claim 16 , wherein the transaction message includes a device identification associated with the second computer.
18. The first computer of claim 17 , wherein the transaction message is modified by the first computer based on the device identification.
19. The first computer of claim 18 , wherein the device identification is associated within the intermediary server to a third security association between the intermediary server and the second computer.
20. The first computer of claim 14 , wherein the second computer is a personal computer.
21. A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium storing instructions to be implemented on a first computer including at least one processor, the instructions when executed by the at least one processor cause the first computer to perform a method, the method comprising:
encrypting first data of a first data path in a transaction using a first security association, wherein:
the first data path is through an intermediary server that provides connectivity between the first computer and a second computer; and
the transaction comprises a transaction message that includes control data and payload data;
transmitting the control data to the intermediary server, wherein:
the control data includes a token associated with the intermediary server;
the token provides transaction routing information;
the second computer receives the first data from the intermediary server; and
the first data is decrypted;
encrypting second data of a second data path using a second security association, wherein the second data path is distinct from the intermediary server;
and
transmitting the payload data through the second data path.
