Abstract:
A secure instant messaging (IM) system integrates secure instant messaging into existing instant messaging systems. A certificate authority (CA) issues security certificates to users binding the user's IM screen name to a public key, used by sending users to encrypt messages and files for the user. The CA uses a subscriber database to keep track of valid users and associated information, e.g. user screen names, user subscription expiration dates, and enrollment agent information. A user sends his certificate to an instant messaging server which publishes the user's certificate to other users. Users encrypt instant messages and files using an encryption algorithm and the recipient's certificate. A sending user can sign instant messages using his private signing key. The security status of received messages is displayed to recipients.

Claim (Index 18):
The method of  claim 17  wherein the messaging client device is a second messaging client device, and further comprising:\n receiving an encrypted message from the second messaging client device, wherein the encrypted message is encrypted using the public key issued to the first user; and \n sending the encrypted message to a first messaging client device associated with the first user.
