Abstract
The invention enables a registered PEAD user to exchange a secure message with another registered PEAD user by using the user ID and the user public key information in the server. The sender can retrieve the public key information from the server 1201 using the receiver's user ID as an index; then the sender can derive the shared secret using the receiver's public key. The sender then can encrypt the message with the shared secret and send it over to a server with the other PEAD user's (receiver's) ID appended with the sender's user ID over the wireless network and/or Internet. The server then stores the message and forwards the message to the receiver once the receiver's PEAD is polling for messages. (It is understood in the art that the server can push the messages to the receiver's PEAD).The receiving PEAD user can use the sender's PEAD user ID and sender's public key information to derive the shared secret to decrypt a received secure message. Once a shared secret is computed or established by protocol between two users, that shared secret can be saved in the PEAD for future communication encryption/decryption usage.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
