Public Key Infrastructure
A system of digital certificates (and other registration authorities) that verify and authenticate the validity of each party involved in an Internet transaction. PKI lays the groundwork for requiring users to have an issued key (or password) to access information. PKIs are in development; there is no universal PKI or even a single agreed-upon standard for setting up a PKI, but nearly everyone agrees that reliable PKIs are necessary before e-commerce can become widespread.
