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 method of processing messages being composed at a computing device, wherein steps of the method are performed by at least one application executing on the computing device, the method comprising the steps of:

receiving a user request to compose a message;

receiving a user input identifying an intended message recipient for the message, during user composition of the message;

requesting certificate data from a certificate store, in response to receiving the user input;

detecting when the certificate data has been retrieved to the computing device;

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 computing device; and

receiving a user direction to send the message;

wherein the requesting, detecting and retrieving steps are initiated before the step of receiving the user direction.

2. The method of claim 1, further comprising the steps of:

further processing the message using requested certificate data; and

optionally sending the message.

3. The method of claim 1, wherein the certificate data requested from the certificate store in response to receiving the user input comprises a certificate associated with the message recipient.

4. The method of claim 1, wherein the certificate store resides on a server remote from the computing device.

5. The method of claim 1, wherein the certificate data comprises an S/MIME certificate.

6. The method of claim 1, wherein the certificate data comprises a PGP key.

7. A computer-readable storage medium upon which a plurality of instructions are stored, the instructions for performing a method of processing messages being composed at the computing device, the method comprising:

receiving a user request to compose a message;

receiving a user input identifying an intended message recipient for the message, during user composition of the message;

requesting certificate data from a certificate store, in response to the user input;

detecting when the certificate data has been retrieved to the computing device;

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 computing device; and

receiving a user direction to send the message;

wherein said requesting, detecting and retrieving are initiated before receiving the user direction.

8. A system for processing messages being composed at a computing device, wherein the system comprises a policy engine connected to the computing device, and wherein the system comprises a processor configured to:

receive a user request to compose a message;

receive a user direction to send the message;

receive a user input identifying an intended message recipient for the message, during user composition of the message;

request certificate data from a certificate store, in response to the user input and before the user direction to send the message is received;

detect when the certificate data has been retrieved to the computing device before the user direction to send the message is received; and

retrieve certificate status data before the user direction to send the message is received;

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 computing device.

9. The system of claim 8, wherein the policy engine resides on a device remote from the computing device.

10. The system of claim 8, wherein the policy engine is implemented in a PGP Universal Server.

11. The system of claim 8, wherein the policy engine is implemented in an EMS.

12. The system of claim 8, wherein the computing device comprises a mobile device.

13. A method of processing messages being composed at a computing device, wherein steps of the method are performed by at least one application executing on the computing device, the method comprising the steps of:

receiving a user request to compose a message;

receiving a user input identifying an intended message recipient for the message, during user composition of the message;

requesting certificate data from a certificate store, in response to receiving the user input;

detecting when the certificate data has been retrieved to the computing device;

determining whether updated certificate status data needs to be retrieved, wherein said determining whether updated certificate status data needs to be retrieved is initiated upon detecting that the certificate data has been retrieved to the computing device;

retrieving certificate status data if it is determined that updated certificate status data needs to be retrieved; and

receiving a user direction to send the message;

wherein the requesting, detecting, determining and retrieving steps are initiated before the step of receiving the user direction.

14. The method of claim 13, further comprising the steps of:

further processing the message using requested certificate data; and

optionally sending the message.

15. The method of claim 13, wherein the certificate data requested from the certificate store in response to receiving the user input comprises a certificate associated with the message recipient.

16. The method of claim 13, wherein the certificate store resides on a server remote from the computing device.

17. The method of claim 13, wherein the certificate data comprises an S/MIME certificate.

18. The method of claim 13, wherein the certificate data comprises a PGP key.

19. A computer-readable storage medium upon which a plurality of instructions are stored, the instructions for performing a method of processing messages being composed at the computing device, the method comprising:

receiving a user request to compose a message;

receiving a user input identifying an intended message recipient for the message, during user composition of the message;

requesting certificate data from a certificate store, in response to receiving the user input;

detecting when the certificate data has been retrieved to the computing device;

determining whether updated certificate status data needs to be retrieved, wherein said determining whether updated certificate status data needs to be retrieved is initiated upon detecting that the certificate data has been retrieved to the computing device;

retrieving certificate status data if it is determined that updated certificate status data needs to be retrieved; and

receiving a user direction to send the message;

wherein the requesting, detecting, determining and retrieving steps are initiated before the step of receiving the user direction.

20. A system for processing messages being composed at a computing device, wherein the system comprises a policy engine connected to the computing device, and wherein the system comprises a processor configured to:

receive a user request to compose a message;

receive a user direction to send the message;

receive a user input identifying an intended message recipient for the message, during user composition of the message;

request certificate data from a certificate store, in response to receiving the user input and before the user direction to send the message is received;

detect when the certificate data has been retrieved to the computing device before the user direction to send the message is received;

determine whether updated certificate status data needs to be retrieved, upon detecting that the certificate data has been retrieved to the computing device and before the user direction to send the message is received; and

retrieve certificate status data before the user direction to send the message is received, if it is determined that updated certificate status data needs to be retrieved.

21. The system of claim 20, wherein the policy engine resides on a device remote from the computing device.

22. The system of claim 20, wherein the policy engine is implemented in a PGP Universal Server.

23. The system of claim 20, wherein the policy engine is implemented in an EMS.

24. The system of claim 20, wherein the computing device comprises a mobile device.
