Abstract

A system and method for processing messages being composed by a user of a computing device (e.g. a mobile device). Embodiments are described in which the performance of certain tasks is initiated before a direction is received from a user to send a message being composed by the user. This may involve, for example, “pre-fetching” security-related data that will be required in order to send a message that is in the process of being composed by the user securely. Such data may include security policy data, certificate data, and/or certificate status data, for example.

Claims

1. A mobile device comprising a microprocessor, wherein the microprocessor is configured to:

identify a message recipient for a message, during composition of the message;

request certificate data from a certificate store, wherein the certificate data corresponds to the message recipient;

detect when the certificate data has been retrieved to the mobile device;

retrieve certificate status data, wherein the certificate status data is used to verify the status of a certificate upon detecting that the certificate data has been retrieved to the mobile device; and

receive a user direction to send the message;

wherein the processor is configured to initiate requesting the certificate data, detecting when the certificate data has been retrieved to the mobile device and retrieving the certificate status data before the user direction is received.

2. The device of claim 1, wherein the processor is further configured to process the message using requested certificate data.

3. The device of claim 1, wherein the processor is further configured to send the message to the message recipient.

4. The device of claim 1, wherein the certificate data requested from the certificate store comprises a certificate associated with the message recipient.

5. The device of claim 1, wherein the certificate store resides on a server remote from the mobile device.

6. The device of claim 1, wherein the certificate data comprises an S/MIME certificate.

7. The device of claim 1, wherein the certificate data comprises a PGP key.

8. A mobile device comprising a microprocessor, wherein the microprocessor is configured to:

identify a message recipient for a message, during composition of the message;

request certificate data from a certificate store, wherein the certificate data corresponds to the message recipient;

detect when the certificate data has been retrieved to the mobile device;

determine that updated certificate status data is to be retrieved upon detecting after the certificate data has been retrieved to the mobile device;

retrieve certificate status data upon determining that updated certificate status data is to be retrieved; and

receive a user direction to send the message;

wherein the processor is configured to initiate requesting the certificate data;

detecting when the certificate data has been retrieved to the mobile device and retrieving the certificate status data before the user direction is received.

9. The device of claim 8, wherein the processor is further configured to process the message using requested certificate data.

10. The device of claim 8, wherein the processor is further configured to send the message.

11. The device of claim 8, wherein the certificate data requested from the certificate store comprises a certificate associated with the message recipient.

12. The device of claim 8, wherein the certificate store resides on a server remote from the mobile device.

13. The device of claim 8, wherein the certificate data comprises an S/MIM E certificate.

14. The device of claim 8, wherein the certificate data comprises a PGP key.

15. A mobile device comprising:

means for identifying a message recipient for a message, during user composition of the message;

means for requesting certificate data from a certificate store, wherein the certificate data corresponds to the message recipient;

means for detecting when the certificate data has been retrieved to the mobile device;

means for retrieving certificate status data, wherein the certificate status data is used to verify the status of a certificate upon detecting that the certificate data has been retrieved to the mobile device; and

means for receiving a user direction to send the message;

wherein the requesting the certificate data, detecting when the certificate data has been retrieved to the mobile device and retrieving the certificate status data is initiated before the user direction is received.

16. The device of claim 15, further comprising means for processing the message using requested certificate data.

17. The device of claim 15, further comprising means for sending the message to the message recipient.

18. The device of claim 15, wherein the certificate data requested from the certificate store comprises a certificate associated with the message recipient.

19. A mobile device comprising:

means for identifying a message recipient for a message, during user composition of the message;

means for requesting certificate data from a certificate store, wherein the certificate data corresponds to the message recipient;

means for detecting when the certificate data has been retrieved to the mobile device;

means for determining that updated certificate status data is to be retrieved after detecting that the certificate data has been retrieved to the mobile device;

means for retrieving certificate status data upon determining that updated certificate status data is to be retrieved; and

means for receiving a user direction to send the message;

wherein the requesting the certificate data, detecting when the certificate data has been retrieved to the mobile device and retrieving the certificate status data is initiated before the user direction is received.

20. The device of claim 19, further comprising means for processing the message using requested certificate data.

21. The device of claim 19, further comprising means for sending the message to the message recipient.

22. The device of claim 19, wherein the certificate data requested from the certificate store comprises a certificate associated with the message recipient.
