Abstract

A method and apparatus for providing intelligent error messaging is disclosed wherein a user of a mobile communications device is provided with descriptive error messaging information to assist the user in overcoming errors associated with the processing of electronic messages and data. For example, when the mobile device is being used to decrypt a cryptographically secured electronic message, and a problem is encountered, program logic of the device provides the user with (1) an indication of exactly what problem is preventing opening of the message, for example, a required cryptographic key is not available; (2) an indication of exactly what may be done to overcome the problem, for example, what utilities should be run on the device; and (3) exactly what data, if any, needs to be downloaded to the device, for example, what cryptographic keys should be downloaded.

Claims

1. An electronic communications device comprising:

a receiver for receiving electronic messages;

a processor capable of processing said electronic messages; and

program logic resident on a memory of said electronic communications device operable to

determine if an electronic mail message received at the electronic communications device is encrypted,

if the received electronic mail message is encrypted, determine if an encryption key for decrypting the received electronic mail message is present on the electronic communications device, and

if the encryption key is not present on the electronic communications device, automatically display an intelligent error message;

wherein said intelligent error message comprises an indication that the encryption key is not present on the electronic communications device and information on how to retrieve the encryption key.

2. The electronic communications device of claim 1, wherein said intelligent error message further comprises information identifying in a digital certificate that comprises data for decrypting the received electronic mail message.

3. The electronic communications device of claim 2, wherein the digital certificate is downloaded to the electronic communications device.

4. The electronic communications device of claim 1, wherein said program logic is resident on said electronic communications device.

5. The electronic communications device of claim 1, wherein the electronic communications device is connected via an interface to a host processor that is capable of performing operations in accordance with said intelligent error message.

6. The electronic communications device of claim 5, wherein said interface is hard-wired.

7. The electronic communications device of claim 5, wherein said interface is wireless.

8. The electronic communications device of claim 1, wherein the encryption key is a private key of a public key private key pair.

9. A wireless communications device comprising:

a processor capable of processing electronic messages received by the wireless communications device; and

program logic operable to

determine if an electronic mail message received by the wireless communications device is encrypted, if the received electronic mail message is encrypted, determine if an encryption key for decrypting the received electronic mail message is present on the wireless communications device, and if the encryption key is not present on the wireless communications device, automatically display an intelligent error message;

wherein said intelligent error message comprises an indication that the encryption key is not present on the wireless communications device and information on how to retrieve the encryption key.

10. The wireless communications device of claim 9, wherein said intelligent error message further comprises information identifying a digital certificate that comprises data for decrypting the received electronic mail message.

11. The wireless communications device of claim 10, wherein said digital certificate is downloaded to said wireless communications device from a host processor.

12. The wireless communications device of claim 9, wherein the encryption key is a private key of a public key private key pair.

13. A method of processing electronic messages for viewing on a wireless communications device comprising:

receiving an electronic mail message on said wireless communications device;

processing the received electronic mail message for display on said wireless communications device;

determining if the received electronic mail message is encrypted;

if the received electronic mail message is encrypted, determining if an encryption key for decrypting the received electronic mail message is present on the wireless communications device; and

if the encryption key is not present on the wireless communications device, automatically displaying an intelligent error message on the wireless communications device;

wherein the intelligent error message comprises a first message indicating that the encryption key is not present on the wireless communications device and a second message providing detailed information on how to retrieve the encryption key.

14. The method of claim 13, wherein said intelligent error message further comprises a third message comprising information identifying a digital certificate that comprises data for decrypting the electronic mail message.

15. The method of claim 14, further comprising downloading the digital certificate to the wireless communications device.

16. The method of claim 13, wherein the encryption key is a private key of a public key private key pair.
