    How to build a PKI that works Peter Gutmann University of Auckland How to build an X.509 PKI that works Peter Gutmann University of Auckland Preliminaries Whose PKI are we talking about here? •Not SSL certs –Certificate manufacturing, not PKI It’s just an expensive way of doing authenticated DNS lookups with a TTL of one year. Plenty of PK, precious little I — Peter Gutmann on the crypto list •Not PGP, SPKI, *ML, etc –Doing fairly well in their (low-I) area •Not government PKI initiatives –Government IT project reality distortion field, keep pumping in money until it cries Uncle –Even then, the reality distortion has failed in parts of Europe, Australia Preliminaries (ctd) This is PKI for the rest of us •Businesses, individuals, etc Talk covers exclusively technical issues •Policies are someone else’s problem Ted says that whenever he gets asked a religious question he doesn’t understand he always responds with “Ah, that must be an ecumenical matter” which universally produces nods of admiration at the profound wisdom of the statement. It seems that that the PKIX list equivalent is “Ah, that must be a policy matter” — Father Ted (via Anon) •Some religion may sneak in Preliminaries (ctd) Microsoft bashing: An apology in advance •Their PKI software is the most widespread, and features prominently in examples because of this •There is no indication that other software is any better, it just gets less publicity It may be a little controversial… 56th IETF agenda item, submitted as a joke when someone pointed out that PKIX didn’t have any agenda What needs to be done to make PKI work? This forum will be open to all PKIX members, and will constitute a large pool filled knee-deep with custard.

  • Security Policies for the Federal Public Key Infrastructure
    Security Policies for the Federal Public Key Infrastructure Noel A. Nazario Security Technology Group National Institute of Standards and Technology Abstract This document discusses provisions for the handling of security policies in the proposed Federal Public Key Infrastructure (PKI). Federal PKI policies deal with the generation, deactivation, and dissemination of public key certificates, the integrity of the infrastructure, maintenance of records, identification of certificate holders, and the establishment of trust relationships between Certification Authorities (CAs). The verification of a digital signature is not sufficient indication of the trustworthiness of an electronic message or data file. The verifier needs to factor the trustworthiness of the CAs involved in the certification of the sender. To accomplish this, the verifier needs to examine the certificate policy for those CAs. The Federal PKI Technical Security Policy establishes guidelines for the operation of Federal CAs and the identification of the parties requesting certification. It also defines Policy Approving Authorities (PAA) responsible for assessing the policies and operational practices of all Federal CAs within a domain and assigning them corresponding Federal Assurance Levels. These assurance levels may be used in lieu of a certificate policy when making an on-line determination of the trustworthiness of a certificate. Key words Certificate policy, Federal Assurance Levels, PAA, PKI, Policy Approving Authority, public key infrastructure, security policy.

  • A Pki Architecture Using Open Source Software for E- Government Services in Romania
    Nicusor Vatra et al./ Indian Journal of Computer Science and Engineering (IJCSE) A PKI ARCHITECTURE USING OPEN SOURCE SOFTWARE FOR E- GOVERNMENT SERVICES IN ROMANIA NICUȘOR VATRA The Doctoral School Department, The Bucharest Academy of Economic Studies, 6, Romana Square, district 1 Bucharest, 010374, Romania [email protected] http://doctorat.ase.ro Abstract This article presents an architecture based on Open Source software that promote citizen’s access to electronic services in a secure way and attempt to make an analysis between two different Open Source Public Key Infrastructure software: OpenCA PKI and EJBCA. The architecture represents a suitable solution for a large enterprise or public administration that enables security and easy management of electronic documents in e-Government Services area. Keywords: - public key infrastructure, e-Government Services, Open Source, encryption, electronic signature. 1. Introduction The recent technological developments such as extension of modern communication and particularly the Internet boom have made the electronic world to create brand new opportunities for realizing transactions on the Internet. Due to ease to use, flexibility but also lack of explicit rules and restrictions, the Internet has become the most popular platform and the most important communication channel for the electronic transactions. One of the major characteristics of any electronic transactions performed on the Internet is trust. On the Internet, where there is no direct contact between parties and millions of users exchange information daily is necessary to take security measures to validate our collaborators, customers and suppliers prior to the exchange information’s, goods and services or make payments. Public Key Infrastructure (PKI) provides the needed trust using Trusted Third Parties (TTPs) known as Certification Authorities (CAs) [1].
