Abstract
Many Internet applications use public key technology for security purposes. These applications (i.e. World Wide Web protocols, Internet protocol security, digital signatures, user authentication and E-mail) require a public key infrastructure (PKI) to securely manage public encryption keys for widely distributed users or systems. 1 The use of public key technology requires that the user of a public key be confident that the public key belongs to the correct remote subject (i.e. person or system) with which the encryption mechanism will be used. 2 This confidence is obtained through the use of public key certificates. 2
