Projects:

Public Key Infrastructure (PKI). PKI is a major focus area for the Computer Security Division. I am currently developing technical specifications for interoperable PKI components and planning development of a reference implementation of those specifications. I participate in the IETF's Internet Public Key Infrastructure (PKI-X) standards development, and am supporting government agencies planning near-term procurements of PKI components.
