ABSTRACT
Existing Grid technology has been foremost designed with performance and scalability in mind. When
using Grid infrastructure for medical applications, privacy and security considerations become paramount.
Privacy aspects require a re-thinking of the design and implementation of common Grid middleware
components. This chapter describes a novel security framework for handling privacy sensitive infor-
mation on the Grid, and describes the privacy and security considerations which impacted its design.
INTRODUCTION
as Biology, Pharmaceutics, and Medical research
have shown increasing interest in using Grids for
their applications. Grid middleware, including
gLite (gLite, n.d.) and the Globus Toolkit (Globus,
n.d.), hides many aspects such as data distribution
and replication from users of the system. As a
result, users are often unaware that jobs and data
are transferred through multiple Grid components
in different administrative domains implicitly.
This makes it hard for users to understand the
Most current Grid middleware is designed primar-
ily for high-performance and high-throughput
computing and data storage (LHC, n.d.; Foster,
Kesselman, & Tuecke, 2001). Initially, Grid
infrastructure aimed mostly at the Physics com-
munity, but recently many other domains, such
