<p>A method for securely sending email between a sender (16) and a receiver over a public communications network (20) using a standard browser. The sender of the message first opens a standard web browser (30) and points it to a web site operated by an intermediary party (32). Then, the message sender enters a secure communication session with the intermediary party and logs into the intermediary party's web site with a valid access ID and password pair (34). After successful log in, the sender composes and submits a confidential email (50) to the intermediary party's web site (52). The intermediary party then encrypts the email with a public key belonging to the receiver and signs the email with its own private key. Next, the intermediary party sends the encrypted email to the receiver. The receiver is then able to access the email using an encrypted password.</p> |
