ABSTRACT
Fifth generation computer systems will use large
numbers of processors to achieve high performance. In
this paper a capability-based operating system designed
for this environment is discussed. Capability-based
operating systems have traditionally required large,
complex kernels to manage the use of capabilities. In
our proposal, capability management is done entirely by
user programs without giving up any of the protection
aspects normally associated with capabilities. The
basic idea is to use one-way functions and encryption
to protect sensitive information. Various aspects of
the proposed system are discussed.
