The Directory-Enabled PKI Appliance: Digital Signatures Made Simple, Approach and Real World Experience - April 15, 2008

This paper presents a novel approach for a PKI based digital signature system for documents in an enterprise setting. A centralized appliance securely stores users' private signing keys. The appliance interfaces with the existing enterprise directory to automatically provision users' keys and certificates. Users authenticate to the appliance using their existing directory credentials in order to access their signing keys. Client applications send document hash values to the appliance to be...

A Scalable PKI for a National Grid Service - April 15, 2008

This paper describes work to expand the PKI for the UK National Grid Service (NGS), to integrate it with site authentication and improve usability. This work is complementary to the UK Shibboleth deployment. As the NGS grows to support wider and larger scientific communities, the paper investigate how to improve usability by tying in Virtual Organisation management into the PKI framework.

PKI Interoperability by an Independent, Trusted Validation Authority - April 15, 2008

Interoperability between PKIs (Public Key Infrastructure) is a major issue in several electronic commerce scenarios. This paper suggests an approach based on a trust model where an independent Validation Authority (VA) replaces Certification Authorities (CA) as the trust anchor for the receiver of a PKI certificate (the Relying Party, RP). By trusting the VA, the RP is able to trust all CAs that the VA can answer for. The main issue is not technical validation of the certificates but assessment.

PKI: Ten Years Later - April 15, 2008

This paper examines the history and evolution of so-called Public Key Infrastructure (PKI). It compares the original definition of PKI with a broader and more flexible definition that better reflects the variety of implementation philosophies available today. This current definition shows how the understanding of this technology has matured (although its essential characteristics have remained unchanged) and is derived, at least in part, from an evaluation and comparison of several quite...

Role Sharing in Password-Enabled PKI - April 15, 2008

Password-enabled PKI schemes simplify the management of end users' private keys by storing them in password-protected form on a centralized on-line server. Under such schemes an end user needs only remember his password and can access his private key from anywhere the centralized server is available. Existing password-enabled PKI schemes are based on the single-user model where a private key is owned by one user. This paper presents mechanisms to support role sharing in password-enabled PKI. In.
