OpenPGP, an IETF Proposed Standard based on PGP R application, has its own Public Key Infrastructure (PKI) architecture which is different from the one based on X.509, another standard from ITU. This paper describes the OpenPGP PKI; the historical perspective as well as its current use. The authors also compare three PKI technologies standardized by IETF: OpenPGP, PKIX (X.509), and SPKI/SDSI. Since the OpenPGP PKI works without a registration authority nor certification authority, it fits well with the Internet communication with voluntary community.
