Identity Management Systems. Edition No. 1
VDM Publishing House, Oct 2008, Pages: 120
Internet-scale Identity Management is a fascinating
topic with many facets. The prevalent solution today
duplicates identity information at many, separate
places and uses as many different passwords to access
and protect them. Users cannot handle the resulting
plethora of credentials and weak security is the
result. Plenty of technical approaches
to remedy the situation exist, but little of them
have managed to offer a complete and secure solution.
Above all of them floats the keyword Single Sign-On
as a seemingly trivial way out of the mess. But a
great number of pitfalls prevented the success of
almost all systems proposed so far. This book
discusses prominent systems of the past and
shows why they have failed to be adapted for the
Internet. Based on a study of these deficiencies, we
derive basic requirements to be adapted by future
systems. An overview and comparison brings light into
the jungle of current approaches. Among others, we
discuss Windows CardSpace, OpenID, and the Liberty
Alliance Project. Practial examples complete the
discussions.
