Abstract

A digital security bubble encapsulation is disclosed. A first key and a device identifier of at least one recipient is requested from a first server. A message containing one or more components is encrypted using a second key. The second key is encrypted using the first key. The encrypted message, the encrypted second key, and the device identifier are encapsulated in a digital security bubble encapsulation. The digital security bubble encapsulation is transmitted to a second server.

First claim

What is claimed is:

1. A system, comprising:
a processor configured to:
request an identifier associated with a first recipient, wherein the identifier comprises at least one of an application identifier and a device identifier;
encrypt a message, to be sent to at least the first recipient, using a first key;
encrypt the first key using a second key associated with the first recipient,

wherein the processor is configured to obtain the second key and the identifier from a server;
encapsulate the encrypted message, the encrypted first key, and the identifier in a digital security bubble encapsulation; and
transmit the digital security bubble encapsulation to the first recipient; and

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

2. The system of claim 1 wherein the processor is further configured to generate the first key.

3. The system of claim 1 wherein the identifier comprises a device identifier.

4. The system of claim 3 wherein the device identifier is based at least in part on at least one hardware identifier.

5. The system of claim 1 wherein the identifier comprises an application identifier.

6. The system of claim 1 wherein the second key is a public key.

7. The system of claim 3 wherein the device identifier is based at least in part on a plurality of hardware identifiers associated with a plurality of hardware components.

8. The system of claim 1 wherein the processor is configured to request a plurality of public keys and a plurality of identifiers associated with a plurality of recipients.

9. The system of claim 8 wherein the processor is further configured to encrypt the first key with each of the received public keys, to produce a plurality of encrypted first keys.

10. The system of claim 9 wherein the digital security bubble encapsulation includes the plurality of encrypted first keys.

11. The method of claim 1 further comprising requesting a plurality of public keys and a plurality of identifiers associated with a plurality of recipients.

12. The method of claim 11 further comprising encrypting the first key with each of the received public keys, to produce a plurality of encrypted first keys.

13. A method, comprising:
requesting an identifier associated with a first recipient, wherein the identifier comprises at least one of an application identifier and a hardware identifier;
encrypting a message, to be sent to at least the first recipient, using a first key;
encrypting the first key using a second key associated with the first recipient, wherein the second key and the identifier are obtained from a server;
encapsulating the encrypted message, the encrypted first key, and the identifier in a digital security bubble encapsulation; and
transmitting the digital security bubble encapsulation to the first recipient.

14. The method of claim 13 further comprising generating the first key.

15. The method of claim 13 wherein the identifier comprises a device identifier.

16. The method of claim 15 wherein the device identifier is based at least in part on at least one hardware identifier.

17. The method of claim 13 wherein the identifier comprises an application identifier.

18. The method of claim 13 wherein the second key is a public key.

19. The method of claim 15 wherein the device identifier is based at least in part on a plurality of hardware identifiers associated with a plurality of hardware components.

20. A computer program product embodied in a tangible computer readable storage medium and comprising computer instructions for:
requesting an identifier associated with a first recipient, wherein the identifier comprises at least one of an application identifier and a hardware identifier;
encrypting a message, to be sent to at least a the first recipient, using a first key;
encrypting the first key using a second key associated with the first recipient, wherein the second key and the identifier are obtained from a server;
encapsulating the encrypted message, the encrypted first key, and an the identifier in a digital security bubble encapsulation; and
transmitting the digital security bubble encapsulation to the first recipient.
