Abstract

Methods, systems, and products are disclosed for sending secured data, the method including encrypting a first portion of a request for computer services to be performed by a downstream node for decryption by a first node, encrypting a second portion of the request for computer services to be performed by a downstream node for decryption by a second node, and passing the request for computer services to a downstream node.

Claims

1. A method for sending secured data, the method comprising:

encrypting a first portion of a request for computer services to be performed by a downstream node for decryption by a first node;

encrypting a second portion of the request for computer services to be performed by a downstream node for decryption by a second node; and

passing the request for computer services to a downstream node.

2. The method of claim 1 further comprising:

receiving in the first node the request for computer services to be performed by a downstream node;

decrypting the encrypted first portion; and

passing the request for computer services to a downstream node.

3. The method of claim 2 further comprising executing an action in dependence upon the first portion.

4. The method of claim 2 further comprising encrypting, by the first node, a new portion of the request for computer services to be performed by a downstream node.

5. The method of claim 1 further comprising:

receiving in the second node the request for computer services to be

performed by a downstream node; and

decrypting the encrypted second portion

6. The method of claim 1 wherein encrypting a first portion of a request for computer services to be performed by a downstream node for decryption by a first node further comprises encrypting the first portion of the request with the public key for the first node.

7. The method of claim 1 wherein the first node and the second node are intermediary nodes between an initial requestor of computer services and an ultimate destination service provider of the request.

8. A system for sending secured data, the system comprising:

a computer processor;

a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of;

encrypting a first portion of a request for computer services to be performed by a downstream node for decryption by a first node;

encrypting a second portion of the request for computer services to be performed by a downstream node for decryption by a second node; and

passing the request for computer services to a downstream node.

9. The system of claim 8 wherein the computer memory also has disposed within it computer program instructions capable of:

receiving in the first node the request for computer services to be performed by a downstream node;

decrypting the encrypted first portion; and

passing the request for computer services to a downstream node.

10. The system of claim 9 wherein the computer memory also has disposed within it computer program instructions capable of executing an action in dependence upon the first portion.

11. The system of claim 9 wherein the computer memory also has disposed within it computer program instructions capable of encrypting, by the first node, a new portion of the request for computer services to be performed by a downstream node.

12. The system of claim 8 wherein the computer memory also has disposed within it computer program instructions capable of:

receiving in the second node the request for computer services to be performed by a downstream node; and

decrypting the encrypted second portion

13. The system of claim 8 wherein the computer memory also has disposed within it computer program instructions capable of encrypting the first portion of the request with the public key for the first node.

14. A computer program product for sending secured data, the computer program product disposed upon a signal bearing medium, the computer program product comprising computer program instructions capable of:

encrypting a first portion of a request for computer services to be performed by a downstream node for decryption by a first node;

encrypting a second portion of the request for computer services to be performed by a downstream node for decryption by a second node; and

passing the request for computer services to a downstream node.

15. The computer program product of claim 14 wherein the signal bearing medium comprises a recordable medium.

16. The computer program product of claim 14 wherein the signal bearing medium comprises a transmission medium.

17. The computer program product of claim 14 further comprising computer program instructions capable of:

receiving in the first node the request for computer services to be performed by a downstream node;

decrypting the encrypted first portion; and

passing the request for computer services to a downstream node.

18. The computer program product of claim 17 further comprising computer program instructions capable of executing an action in dependence upon the first portion.

19. The computer program product of claim 17 further comprising computer program instructions capable of encrypting, by the first node, a new portion of the request for computer services to be performed by a downstream node.

20. The computer program product of claim 14 further comprising computer program instructions capable of encrypting the first portion of the request with the public key for the first node.
