Certificates are based on public-private key pairs. A certificate contains the certificate owner's identity and public key. Certificates provide a way to exchange public keys for use in authentication. A Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. You can use the device to generate certification requests that contain identifying information and public keys and then send the certification requests to a certification authority. In public-key encryption and decryption, each host has two keys. One key is public and can be made openly available; the other key is private and must be kept secure. Public-key encryption in general works as follows. 1 Tim wants to send a private message to Jenny. Tim generates a public key pair. What is encrypted with one key can only be decrypted using the other. 2 Tim keeps the private key and makes the public key openly available. 3 Tim uses his private key to encrypt the message and sends it to Jenny. 574 Vantage CNM User's Guide
