Quantum Resistant Public Key Cryptography: A Survey

April 14, 2009
Author(s)
Ray A. Perlner, David A. Cooper
Public key cryptography is widely used to secure transactions over the Internet. However, advances in quantum computers threaten to undermine the security assumptions upon which currently used public key cryptographic algorithms are based. In this paper

Symmetric Key Injection onto Smart Cards

December 22, 2008
Author(s)
David A. Cooper, William I. MacGregor
This paper describes architectures for securely injecting secret keys onto smart cards. Specifically, this paper details key injection architectures based on the identity credentials available on the Personal Identify Verification (PIV) Card. The primary

A Recommendation for the Use of PIV Credentials in Physical Access Control Systems (PACS)

November 20, 2008
Author(s)
William I. MacGregor, Ketan L. Mehta, David A. Cooper, Karen A. Scarfone
This document provides best practice guidelines for integrating the PIV Card with the physical access control systems (PACS) that authenticate the cardholders in Federal facilities. Specifically, this document recommends a risk-based approach for selecting

Secure Biometric Match-on-Card Feasibility Report

November 30, 2007
Author(s)
David A. Cooper, Trung-Hung Dang, Philip Lee, William I. MacGregor, Ketan Mehta
FIPS 201, "Personal Identity Verification (PIV) of Federal Employees and Contractors," and its associated special publications define a method to perform biometric match-off-card authentication of a PIV cardholder when the PIV card is inserted into a

A More Efficient Use of D-CRLs

May 1, 2000
Author(s)
David A. Cooper
Δ-Certificate revocation lists (delta-CRLs) were designed to provide a more efficient way to distribute certificate status information. However, as this paper shows, in some environments, if delta-CRLs are used as was originally intended, the benefits of

A Model of Cerificate Revocation

December 1, 1999
Author(s)
David A. Cooper
This paper presents a model for the distribution of revocation information using certificate revocation lists (CRLs). This model is used to highlight inefficiencies in the traditional method of distribution certificate status information using CRLs. Two
