Exploring the Design Space - A brief overview of ubiquitous computing research at the Laboratory for Communication Engineering, Cambridge
- …We shouldn't expect technologies that impact peoples# daily lives to be adopted before they are demonstrated as reliable, useful and simple to deploy. Measured against this criterion ubiquitous computing is still in its infancy. We present an overview of the spectrum of research in ubiquitous syst…

Requirements for Security in Cooperative Work: Two Case Studies
- …The purpose of this work is to provide a source of information about requirements for security and protection in software to support cooperative work. This report should be read in conjunction with its companion report [1], which describes a security model for cooperative work derived in part from t…

A Security Model for Cooperative Work
- …This report proposes a security model designed to support cooperative tasks in which the security of the information used and produced is critical, and where the participants in a task are not equally trusted. This approach will support a range of security policies, including those in which the righ…

Protection of Shared Objects for Cooperative Work
- …This paper discusses the design of a system for the protection of shared persistent information objects that are intended to provide a basis for building cooperative applications. A task-based model of cooperative work is adopted and user and task requirements are based on an earlier case study unde…

Security Requirements for Cooperative Work: A Model and Its System Implications
- …ts of the model A principal is an authority to which access rights can be attributed. Principals may be simple or compound. Simple principals are identifiers for active entities (e.g. Frre Jacques, the chair of the examining board, or Corporate Finance Officer). Compound principals are composed fro…

Modelling QoS Characteristics of Multimedia Applications
- …This paper describes ongoing work on the Djinn framework [MIT97] which aims to provide QoS support to reconfigurable distributed multimedia applications by maintaining a runtime model of the application. The model is of the application's structure, QoS characteristics and integrity constraints. This…

Secure Communication in Non-Uniform Trust Environments
- …: Trust cannot be uniform across wide-area networks. There are regions of local
trust. Within a region of trust, there can be a set of software components (object managers) that are mutually trusting for the purposes of object sharing, but more global trust models should also be… - Cited by 5 (3 self) – Add To MetaCart

Role and Task-based Access Control in the PerDiS Groupware Platform
- …A role- and task-based access control scheme has been developed for use in a class of activities that entail cooperation between principals in a virtual enterprise (VE). Data ownership is associated with the component organisations of a VE, each of which constitutes a trust domain. The role/task mod…
