Digital security bubble

1. A system, comprising:

a processor configured to:

request a public key and a device identifier of at least one recipient from a first server;

encrypt a message containing one or more components using a symmetric key;

encrypt the symmetric key with a public key received in response to the request;

encapsulate the encrypted message, the encrypted symmetric key, and the device identifier in a digital security bubble encapsulation; and

transmit the digital security bubble encapsulation to a second server; and

a memory coupled to the processor and configured to provide the processor with instructions.

2. The system of claim 1 wherein the first and second server are the same.

3. The system of claim 1 wherein the processor is further configured to request an is application identifier of the recipient from the first server.

4. The system of claim 1 wherein at least one component included in the message is a message parameter.

5. The system of claim 4 wherein the message parameter comprises expiration information.

6. The system of claim 1 wherein the processor is further configured to generate the symmetric key.

7. The system of claim 1 wherein the device identifier is based at least in part on a hard drive identifier.

8. The system of claim 1 wherein the device identifier is based at least in part on a motherboard identifier.

9. The system of claim 1 wherein the device identifier is based at least in part on a central processing unit identifier.

10. The system of claim 1 wherein the device identifier is based at least in part on a media access control address.

11. The system of claim 1 wherein the device identifier is based at least in part on a plurality of identifiers associated with a plurality of hardware components.

12. The system of claim 1 wherein the processor is configured to request a plurality of keys and a plurality of device identifiers associated with a plurality of recipients from the server.

13. The system of claim 12 wherein the symmetric key is respectively encrypted with each of the received public keys, resulting in a plurality of encrypted symmetric keys.

14. The system of claim 13 wherein each of the plurality of encrypted symmetric keys is included in a single digital security bubble encapsulation.

15. The system of claim 1 wherein the processor is configured to perform the encapsulation at least in part by performing a spreading function.

16. The system of claim 1 wherein only a designated recipient, having a device with applicable device characteristics, is able to decrypt the message.

17. A method, comprising:

requesting a public key and a device identifier of at least one recipient from a first server;

encrypting a message containing one or more components using a symmetric key;

encrypting the symmetric key with a public key received in response to the request;

encapsulating the encrypted message, the encrypted symmetric key, and the device identifier in a digital security bubble encapsulation; and

transmitting the digital security bubble encapsulation to a second server.

18. The method of claim 17 further comprising requesting an application identifier of the recipient from the first server.

19. The method of claim 17 further comprising generating the symmetric key.

20. A computer program product embodied in a tangible computer readable storage medium and comprising computer instructions for:

requesting a public key and a device identifier of at least one recipient from a first server;

encrypting a message containing one or more components using a symmetric key;

encrypting the symmetric key with a public key received in response to the request;

encapsulating the encrypted message, the encrypted symmetric key, and the device identifier in a digital security bubble encapsulation; and

transmitting the digital security bubble encapsulation to a second server.
