Welcome to IDtrust XML.org.
This is the official community gathering place and information resource for identity and trusted infrastructure standards. The site is hosted by the OASIS IDtrust Member Section, a group that encourages new participation from developers and users. This is an open, vendor-neutral community-driven site, and the public is encouraged to contribute content. See more about this site.
SPKI (stands for "Simple PKI") was an effort, now defunct, to streamline traditional PKI.
The SPKI Working Group of the IETF worked in the late 1990s but was disbanded around 2001.
WPKI is simply the deployment of public key infrastructure using private keys and cryptographic functions in wireless devices, especially mobile phones.
WPKI standards were developed by the WAP (Wireless Application Protocol) Forum, until that group merged with the Open Mobile Alliance (OMA).

The basic idea of PKI -- which can be thought of as a coordinated suite of technlogies, standards, management processes and agreements -- has led to numerous spin off approaches. Some like SPKI ("Simple PKI") have attempted to streamline the approach at the certificate protocol level. Others have deployed the basic elements in different form factors, such as wireless.
Historically the leading "IDtrust" technlogies and frameworks have been mainly based on Public Key Technologies (PKTs) and have been expressed as PKI. There are however other fundamental mechanisms for delivering authentication.
While PKI has been feared by many as being inherently privacy invasive (see for example some of Roger Clarke's work), much work has been done to either manage and design PKIs to be safe with regards to privacy (see e.g. Australian Government PKI Privacy Guidelines) or to proactively enhance privacy using PKI technology (e.g. Privacy Positive Aspects of PKI).
