Despite enthusiastic predictions in the trade press, an X.509-style PKI has so far failed to eventuate to any significant degree. This paper looks at some of the reasons behind this, examining why a pure X.509-style PKI may never appear outside a few closed, highly-controlled environments such as government agencies. On the other hand there are many instances in which situationand application-s...

To succeed, they will have to act more like entrepreneurial market participants: to change their management practices, the types of tenants they house, and the kinds of developments they operate, and to attra...

Problems with certificate revocation status control limit the deployment of Public Key Infrastructure (PKI). Classical certificate paths require revocation control of all certificates on the path. In this paper, we show how the recently proposed NPKI (Nested certificate based PKI) system reduces the number of revocation status controls to at most two. Our analysis also shows that NPKI is not as...

Managing public key certificates revocation has long been a central issue in public key infrastructures. Though various certificate revocation mechanisms have been proposed to address this issue, little effort has been devoted to the empirical analysis of real-world certificate revocation data. In this paper, we conduct such an empirical analysis based on a large amount of data collected from V...

An important reason for this is the insufficient usability PKI-enabled applications are often blamed for [11]. Users’ behavior has turned out to be the biggest risk in security software [10], so usability issues deserve closer attention. Research in t...

This paper addresses the development of trust in the use of Open Data through incorporation of appropriate authentication and integrity parameters for use by end user Open Data application developers in an architecture for trustworthy Open Data Services.The advantages of this architecture scheme is that it is far more scalable, not another certificate authority hierarchy with massive dispersion...
