File server architecture for an open distributed document system
(University of Hertfordshire, 1994)
In this paper we will investigate design and implementation strategies for a file server in an open distributed document system. The aim of the open distributed document system is to provide and environment where a group ...
To whom am I speaking? Remote booting in a hostile world
(University of Hertfordshire, 1994)
We consider the problem of booting a workstation across a network. We allow "maintenance" (that is, change without notice by untrusted parties such as adversaries and system managers) to be freely performed upon the network, ...
Reverse accumulation and attractive fixed points
(1994)
We apply reverse accumulation to obtain automatic gradients and error estimates of functions which include in their computation a convergent iteration of the form y= Φ(y,u), where y and u are vectors. We suggest an ...
Self authenticating proxies
(University of Hertfordshire, 1994)
Authentication and access control are usually implemented as two separate protection mechanisms because they are logically separate functions. A consistent approach to both of these functions is proposed in this paper. In ...
Shrink-wrapped optimism: the DODA approach to distributed document processing
(University of Hertfordshire, 1994)
In this paper we introduce a distributed object-based document architecture called DODA in order to illustrate a novel strategy for achieving both high availability and high integrity in the context of open processing ...
Technique for authentication, access control and resource management in open distributed systems
(1994)
A consistent approach to authentication and access control is proposed. In this new approach, resource management is included. By combining the properties of public key encryption with cascading proxies a single mechanism ...
Optimization and automatic differentiation in Ada : some practical experience
(1994)
This paper describes an investigation into the performance of three Ada packages for automatic differentiation. Two of these implement the forward accumulation approach while the third employs reverse accumulation. Each ...
