PUBLIC KEY INFRASTRUCTURE - USING x.509 CERTIFICATES FOR DEVICE AUTHENICATION HERE A CERT, THERE A CERT, EVERYWHERE A CERT

摘要

The Public Key Infrastructure (PKI) is a security standard designed to bring "trust" to Internet services. PKI is based on public key cryptography and uses digital certificates to authenticate entities to service providers. It is this authentication that provides trust for services offered over the Internet. PKI presents a solution for several issues facing cable, and has been included in several CableLabs~(~R) projects. PKI is based not only on technology, but also policies. All of which will be discussed briefly in this paper.
