Abstract

A digital security bubble encapsulation is received from a sender. The encrypted digital security bubble encapsulation includes an encrypted message, an encrypted first key, and an identifier associated with an intended recipient. The encrypted digital security bubble encapsulation is decrypted. The received identifier and a device identifier are compared. The encrypted first key is decrypted in response to a determination that the identifier received in the digital security bubble encapsulation matches the device identifier. The encrypted message is decrypted using the first key.

First claim

What is claimed is:

1. A system, comprising:
a processor configured to: receive an encrypted encapsulation from a sender, wherein the encrypted encapsulation includes an encrypted message, an encrypted first key, and a device identifier associated with an intended recipient wherein the processor is further configured to receive notification of the encrypted encapsulation from a security platform and download the encrypted encapsulation from the security platform in response to receiving the notification;
decrypt the encrypted encapsulation;
compare the received device identifier with a local device identifier;
decrypt the encrypted first key in response to a determination that the received device identifier matches the local device identifier;
decrypt the encrypted message using the first key to produce a decrypted message; and
provide the decrypted message to a recipient;
a memory coupled to the processor and configured to provide the processor with instructions.

2. The system of claim 1 wherein the device identifier is based at least in part on at least one hardware identifier.

3. They system of claim 1 , wherein the first key is a symmetric key.

4. The system of claim 1 , wherein the encrypted encapsulation includes a plurality of encrypted first keys.

5. The system of claim 4 , wherein each of the plurality of encrypted first keys is encrypted with a second key associated with an intended recipient.

6. The system of claim 1 , wherein the processor is further configured to decrypt the encrypted first key using a second key.

7. The system of claim 6 , wherein the second key is a private key of the recipient.

8. The system of claim 1 , wherein the encrypted encapsulation includes at least one message control option.

9. The system of claim 8 , wherein the at least one message control option includes a lifetime of the message.

10. The system of claim 9 , wherein the processor is further configured to delete the decrypted message after an expiration of the lifetime.

11. The system of claim 1 , wherein the at least one message control option is selected from the group consisting of: sharing, saving, forwarding, recalling, and deleting.

12. A method, comprising:
receiving an encrypted encapsulation from a sender, wherein the encrypted encapsulation includes an encrypted message, an encrypted first key, and a device identifier associated with an intended recipient wherein the processor is further configured to receive notification of the encrypted encapsulation from a security platform and download the encrypted encapsulation from the security platform in response to receiving the notification;
decrypting the encrypted encapsulation;
comparing the received device identifier with a local device identifier;
decrypting the encrypted first key in response to a determination that the received device identifier matches the local device identifier;
decrypting the encrypted message using the first key to produce a decrypted message; and
providing the decrypted message to a recipient.

13. The method of claim 12 wherein the device identifier is based at least in part on at least one hardware identifier.

14. The method of claim 12 , wherein the first key is a symmetric key.

15. The method of claim 12 , wherein the encrypted encapsulation includes a plurality of encrypted first keys, wherein each of the plurality of encrypted first keys is encrypted with a second key associated with an intended recipient.

16. The method of claim 12 , further comprising:
decrypting the encrypted first key using a second key, wherein the second key is a private key of the recipient.

17. The method of claim 12 , wherein the encapsulation includes at least one message control option selected from the group consisting of message lifetime, sharing, saving, forwarding, recalling, and deleting.

18. The method of claim 17 , further comprising:
deleting the decrypted message after an expiration of the lifetime option.

19. A computer program product embodied in a tangible computer readable storage medium and comprising computer instructions for:
receiving an encrypted encapsulation from a sender, wherein the encrypted encapsulation includes an encrypted message, an encrypted first key, and a device identifier associated with an intended recipient wherein the processor is further configured to receive notification of the encrypted encapsulation from a security platform and download the encrypted encapsulation from the security platform in response to receiving the notification;
decrypting the encrypted encapsulation;
comparing the received device identifier with a local device identifier;
decrypting the encrypted first key in response to a determination that the received device identifier matches the local device identifier;
decrypting the encrypted message using the first key to produce a decrypted message; and
providing the decrypted message to a recipient.

20. The computer program product of claim 19 , further comprising computer instructions for:
deleting the decrypted message after an expiration of a lifetime option included in encapsulation.
