Abstract
As computers become pervasive in environments like the
home and community, data repositories that can maintain
the long term state of applications will become increasingly
important. Because of the greater reliance of people on
such applications and the potentially sensitive nature of the
data manipulated by them, the repository must be highly
available and it should provide secure access to data. Furthermore,
many different types of data, ranging from private
data belonging to a single user to data shared across
different users may be stored in the repository. We present
the design of a distributed data repository, called a secure
store, which can meet the data access needs of diverse applications.
We develop protocols that replicate data at multiple
servers to enhance availability and work even when
a limited number of compromised servers exhibit arbitrary
failure behavior. We also discuss how the nature of the data
that is stored in the secure store impacts the availability and
costs associated with data access.
