Asymmetric Key Algorithms
Previously you learned about asymmetric key algorithms and you should understand that asymmetric encryption requires two keys: public and private. As a review, using the flashcards define asymmetric key encryption, public key, private key, and digital certificate. Then read the section on asymmetric encryption.
In most Certificate Authority systems, there are different levels of certificates, and each level requires different forms of identification. Certificates with higher class levels generally require more information when requested including the information that was requested for the previous level.
The information requested by a Registration Authority is shown below.
