System and method for compressing secure E-mail for exchange with a mobile data communication device
View Patent ↗A system and method are provided for pre-processing encrypted and/or signed messages at a host system before the message is transmitted to a wireless mobile communication device. The message is received at the host system from a message sender. There is a determination as to whether any of the message receivers has a corresponding wireless mobile communication device. For each message receiver that has a corresponding wireless mobile communication device: the message is processed so as to modify the message with respect to encryption and/or authentication aspect. The processed message is transmitted to a wireless mobile communication device that corresponds to the first message receiver. The system and method may include post-processing messages sent from a wireless mobile communications device to a remote system. Authentication and/or encryption message processing is performed upon the message. The processed message may then be sent through the remote system to one or more receivers.
1. A method of reducing size of an encoded message at a host system before the encrypted message is transmitted to a wireless mobile communication device, the method comprising:
receiving at the host system the encoded message from a message sender addressed to at least one message receiver, the encoded message comprising a digital signature, a certificate, and a message body; and
determining whether any of the at least one message receiver has a corresponding wireless mobile communication device; and
for each message receiver that has a corresponding wireless mobile communication device:
rearranging the digital signature and certificate in the encoded message so that the message body is transmitted to the wireless mobile communications device before the digital signature and the certificate; and
transmitting the processed message to said corresponding wireless mobile communication device.
2. The method of claim 1 , wherein the digital signature is transmitted to the wireless mobile communications device before the certificate is transmitted.
3. The method of claim 2 , wherein the certificate is transmitted to the wireless mobile communications device in response to a request from the wireless mobile communications device.
4. The method of claim 1 , further comprising, for each message receiver that has a corresponding wireless mobile communication device, verifying the digital signature and indicating a digital signature verification status.
5. The method of claim 1 , wherein the encoded message comprises a Secure Multipurpose Internet Mail Extensions (S/MIME) e-mail message.
6. The method of claim 1 , wherein the encoded message is encrypted according to Pretty Good Privacy.
7. A system for reducing size of an encoded message for transmission to a wireless mobile communication device, the system comprising:
a host system configured to receive the encoded message from a message sender addressed to at least one message receiver, the encoded message comprising a digital signature, a certificate, and a message body; and
a wireless connector system associated with the host system and configured to determine whether any of the at least one message receiver has a corresponding wireless mobile communication device, and, for each message receiver that has a corresponding wireless mobile communication device:
rearrange the digital signature and certificate in the encoded message so that the message body is transmitted to the wireless mobile communications device before the digital signature and the certificate; and
transmit the processed message to said corresponding wireless mobile communication device.
8. The system of claim 7 , wherein the digital signature is transmitted to the wireless mobile communications device before the certificate is transmitted.
9. The system of claim 8 , wherein the certificate is transmitted to the wireless mobile communications device in response to a request from the wireless mobile communications device.
10. The system of claim 7 , wherein the wireless connector system is further configured to, for each message receiver that has a corresponding wireless mobile communication device, verify the digital signature and indicate a digital signature verification status.
11. The system of claim 7 , wherein the encoded message comprises a Secure Multipurpose Internet Mail Extensions (S/MIME) e-mail message.
12. The system of claim 7 , wherein the encoded message is encrypted according to Pretty Good Privacy.
13. A non-transitory computer readable medium storing instructions executable by a processor, the instructions for carrying out a method of reducing size of an encoded message at a host system before the encrypted message is transmitted to a wireless mobile communication device, the method comprising:
receiving at the host system the encoded message from a message sender addressed to at least one message receiver, the encoded message comprising a digital signature, a certificate, and a message body; and
determining whether any of the at least one message receiver has a corresponding wireless mobile communication device; and
for each message receiver that has a corresponding wireless mobile communication device:
rearranging the digital signature and certificate in the encoded message so that the message body is transmitted to the wireless mobile communications device before the digital signature and the certificate; and
transmitting the processed message to said corresponding wireless mobile communication device.
14. The computer readable medium of claim 13 , wherein the digital signature is transmitted to the wireless mobile communications device before the certificate is transmitted.
15. The computer readable medium of claim 14 , wherein the certificate is transmitted to the wireless mobile communications device in response to a request from the wireless mobile communications device.
16. The computer readable medium of claim 13 , further comprising, for each message receiver that has a corresponding wireless mobile communication device, verifying the digital signature and indicating a digital signature verification status.
17. The computer readable medium of claim 13 , wherein the encoded message comprises a Secure Multipurpose Internet Mail Extensions (S/MIME) e-mail message.
18. The computer readable medium of claim 13 , wherein the encoded message is encrypted according to Pretty Good Privacy.
