Public Key Infrastructure

This paper presents the profiles related to public-key Infrastructure (PKI) for the Internet. The PKI manages public keys automatically through the use of public-key certificates. It provides a basis for accommodating interoperation between PKI entities. A large-scale PKI issues, revokes and manages digital signature public-key certificates to allow distant parties to reliably authenticate each other. A sound digital signature PKI should provide the basic foundation needed for issuing any kind of public-key certificate.
