A method for secure communication and printing, comprising: user entering user and destination information to host; authentication server producing, saving encryption key for the job, user, and destination information into database, and sending to host; host encrypting the job using encryption key and sending job to destination; user entering user and destination information to device; authentication server retrieving encryption key from database, and sending to device; and device decrypting the job using encryption key and releasing job. Authentication at both host and MFP sides disables unauthorized, malicious attack to a user's mailbox, and results in jobs to a mailbox having different dynamic encryption keys, and no password or mailbox PIN trafficking on network. Furthermore, host and MFP can be at different domains. Methods also include secrecy encrypting encryption key; hashing key generator using SHA1, MD5, etc.; password, PIN, RFID, biometrics; and timer module deleting jobs older than threshold value from storage.
