Public Key Infrastructure
PKI

   <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.
