Abstract

The invention relates to methods and apparatus for securely communicating a message between a first communication module and a second communication module. The first communication module receives a first message generated by a user. A secure message routing module is in communication with the first communication module to automatically encrypt the first message to create a final encrypted message. The final encrypted message can only be decrypted by a particular receiver. The automatic encryption that the secure message routing module performs is transparent to the user.

Claims

1. A method for securely communicating a message between a first communication module and a second communication module, the method comprising the steps of:

(a) receiving, by the first communication module, a first message generated by a user; and

(b) automatically encrypting the first message to create a final encrypted message so that only the second communication module can decrypt the final encrypted message,

wherein the automatic encryption is transparent to the user.

2. The method of claim 1, wherein the first message is an e-mail message.

3. The method of claim 1, further comprising the step of transmitting the first message to the first communication module in response to a rule associated with an address of the first message.

4. The method of claim 3, further comprising the step of comparing the address of the first message with a list of addresses.

5. The method of claim 1, further comprising the step of creating a second message having the first message embedded therein.

6. The method of claim 5, further comprising the step of digitally signing the second message to create a first encrypted message.

7. The method of claim 6, further comprising the step of generating a third message having the first encrypted message embedded therein.

8. The method of claim 7, further comprising the step of digitally signing the third message to create a final encrypted message.

9. The method of claim 1, further comprising the step of transmitting the final encrypted message to the second communication module.

10. The method of claim 1, wherein the encryption occurring transparent to the user occurs with an absence of any additional activity of the user besides normal activity for sending a message to the second communication module.

11. The method of claim 1, further comprising the step of decrypting the final encrypted message before delivering to a recipient.

12. The method of claim 11, wherein the decryption is transparent to the recipient.

13. An apparatus for securely communicating a message comprising:

(a) a first communication module receiving a first message generated by a user;

(b) a first secure message routing module in communication with the first communication module to automatically encrypt the first message to create a final encrypted message so that only a particular receiver of the final encrypted message can decrypt the final encrypted message,

wherein the automatic encryption is transparent to the user.

14. The apparatus of claim 13, wherein the first communication module is a master e-mail server.

15. The apparatus of claim 13, further comprising a second secure message routing module in communication with the first secure message routing module.

16. The apparatus of claim 15, wherein the particular receiver is the second secure message routing module.

17. The apparatus of claim 15, further comprising a corporate e-mail server directing the first message to the first communication device based on a predetermined criteria.

18. The apparatus of claim 17, wherein the corporate e-mail server comprises an address table for determination of whether to direct the first message to the first communication device.

19. The apparatus of claim 15, wherein the second secure message routing module further comprises a relay module enabling the second secure message routing module to receive the final encrypted message from the first communication module.

20. The apparatus of claim 15, wherein the second secure message routing module further comprises a secure reply module enabling sending a secure reply message to the first communication module in response to the final encrypted message.

21. The apparatus of claim 15, wherein the second secure message routing module further comprises a message submit module enabling a new message addressed to a recipient to be transmitted to the first communication module for security processing before transmitting to the recipient.

22. The apparatus of claim 15, wherein at least one of the first message and the final encrypted message comprises an e-mail.

23. The apparatus of claim 13, wherein the user comprises at least one of a computer and a person in communication with the first communication module.

24. A method for securely communicating a message between a first communication module and a second communication module, the method comprising the steps of:

(a) receiving, by the second communication module, a final encrypted message transmitted by the first communication module; and

(b) automatically decrypting the final encrypted message to obtain a first message addressed to a user,

wherein the automatic decryption is transparent to the user.

25. A method for securely communicating a message between a first communication module and a second communication module, the method comprising the steps of:

(a) receiving, by the first communication module, a first encrypted message sent by a first user in communication with the second communication module;

(b) receiving, by the first communication module, a second message generated by a second user in communication with the first communication module;

(c) automatically decrypting the final encrypted message to obtain a first message addressed to the second user; and

(d) automatically encrypting the second message to create a second encrypted message so that only the second communication module can decrypt the second encrypted message,

wherein the automatic encryption is transparent to the first user and the second user, and

wherein the automatic decryption is transparent to the first user and the second user.

26. An apparatus for securely communicating a message between a first communication module and a second communication module comprising:

(a) means for receiving, by the first communication module, a first message generated by a user; and

(b) means for automatically encrypting the first message to create a final encrypted message so that only the second communication module can decrypt the final encrypted message,

wherein the means for automatic encryption is transparent to the user.
