Loren Kohnfelder

From Wikipedia, the free encyclopedia

Loren Kohnfelder is best known for his MIT Bsc thesis written in May 1978 describing a practical means of applying public key cryptography to secure network communications.

The Kohnfelder thesis introduced the terms Certificate and Certificate Revocation List as well as introducing numerous other concepts now established as important parts of Public Key Infrastructure. The X.509 certificate specification that provides the basis for SSL, S/MIME and most modern PKI implementations is based on the Kohnfelder thesis.
