  1. PKI Administration Using EJBCA and OpenCA Presented By: Ayesha Ghori and Asra Parveen

  2. PKI: Public Key Infrastructure • A trusted third Party. • Secured communication. • Provides digital certificates that can identify an individual or an organization. • Stores and revokes Certificates. • Provides services like Encryption, digital Signatures, data integrity, key establishment, zero knowledge/minimum knowledge protocols.

  3. PKI Components • Certificate Authority: A CA issues certificates to, and vouches for the authenticity of entities. • Registration Authority: An RA is an administrative function that registers entities in the PKI. • Endentity: An end-entity is a user, such as an e-mail client, a web server, a web browser or a VPN-gateway.

  5. EJBCA and OpenCASoftware Requirements Software Requirements of EJBCA • Java JDK 1.5 – Java 2 Platform Standard Development Kit. • Apache Ant – Java Build Utility, used to compile and build Java programs. • JBoss 4.0.5 – J2EE Application ServerEJBCA download Software Requirements of OpenCA • OpenLDAP. • OpenSSL. • Apache Project. • Apache mod_ssl.

  6. EJBCA • EJBCA is a fully functional Certificate Authority built in Java. • Based on J2EE technology. • Robust • High performance, component based CA. • Flexible and platform independent. • EJBCA can be used as standalone or integrated in any J2EE application.

  7. EJBCA: Architecture

  8. EJBCA Administration • Create and Initialize the Super Administrator • Creating and Configuring data sources • Creating Publishers • Creating Certificate Authorities • Creating Registration Authorities • Creating End Entities • Creating CRL’s • Generating Certificates

  9. The EJBCA Super Admin Certificate

  10. OpenCA • Linux based. • Provides the choice of algorithms- des, des3, idea. • Extensions Provided: SKI and AKI. • In Addition to the PKI components of EJBCA, OpenCA also has a Registration Authority Operator.

  11. OpenCA: Architecture

  12. OpenCA Administration • Initializing the Certification Authority • Create the initial administrator • Create the initial RA Certificate • Submit a Certificate Request • Approve the Certificate • Issue the Certificate • Importing the Root Certificate

  13. User Certificate

  14. Comparison

  15. Conclusion • EJBCA is the simplest to use • Complexity during installation • Provides for automatic CRL updates • OpenCA is the best for Linux users • Manual revocations • Both can be used by various clients
