Public Key Infrastructure
<cryptography, communications> (PKI) A system of public key encryption
using digital certificates from Certificate Authorities and other registration
authorities that verify and authenticate the validity of each party involved in
an electronic transaction.
PKIs are currently evolving and there is no single PKI nor even a single
agreed-upon standard for setting up a PKI. However, nearly everyone agrees that
reliable PKIs are necessary before electronic commerce can become widespread.
