Possibilities for Formal Models of Smart Environments

CAMAC: a context-aware mandatory access control model

Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...

An Integrated Formal Task Specification Method for Smart Environments

Using Meta User Interfaces to Control Multimodal Interaction in Smart Environments

Smart environments bring together multiple users, (interaction) resources and services. This creates complex and unpredictable interactive computing environments that are hard to understand. Users thus have difficulties to build up their mental model of such interactive systems. To address this issue users need possibilities to evaluate the state of these systems and to adapt them according to ...

Implementing a Formally Verifiable Security Protocol in Java Card

This paper describes a case study in refining an abstract security protocol description down to a concrete implementation on a Java Card smart card. The aim is to consider the decisions that have to be made in the development of such an implementation in a systematic way, and to investigate the possibilities of formal specification and verification in the design process and for the final implem...

Modeling Human-Computer Interaction in Smart Spaces: Existing and Emerging Techniques

The main focus of human-computer interaction (HCI) research during the 1980s and much of the 1990s was on desktop computers applied in office settings. Developments within mobile and wireless communication technology, however, have contributed to make computer interaction beyond fixed and predictive desktop settings a reality. This has opened up for new interactive possibilities in and across v...
