摘要： A secure instant messaging system integrates secure text instant messaging and secure file transfers into existing instant messaging systems. At least one certificate authority (CA) is provided that issues a security certificate to a user that binds the user's instant messaging screen name to a public key which is used by other users to encrypt messages and files sent to the user and by the user to decrypt the received messages and files. A subscriber database is used by the CA to keep track of valid users and their associated information, such as: user screen names, user subscription expiration dates, and enrollment agent information. A user sends his certificate to the invention's instant messaging server which publishes the user's certificate to other users by creating a hash value of the user's certificate and sending it to the other users which allows the recipients to decide if they need to update their caches with a new copy of the user's certificate. Instant messages and files are encrypted by a sending user using an encryption algorithm and the recipient's certificate. The sending user can sign instant messages using his private signing key. The security status of each received instant message is displayed to the user.
