SaaS applications have been widely adopted especially by small and medium enterprises. At the same time, the features "multi-tenancy" and "loosely coupled" bring new challenges to enterprises interoperability. On the basis of the layered interoperability model, the paper presents an approach based on interoperability points to implement interoperation between SaaS applications in the service la...

By collaboration, domains share resources effectively. To maintain security properties of individual domains during collaboration is a key issue. When domains employing heterogeneous RBAC policies collaborate via crossdomain role-role mappings, their locally-defined separation of duty constraints face the risk of breaching. We present the requirements for constraint-secure interoperation, prohi...

Over the past decade Intrusion Detection Systems (IDS) have been steadily improving their efficiency and effectiveness in detecting attacks. This is particularly true with signature-based IDS due to progress in attack analysis and attack signature specification. At the same time system complexity, overall numbers of bugs and security vulnerabilities have increased. This has led to the recogniti...

The area of pervasive systems is characterized by high heterogeneity, with thousands of autonomous devices living together, and requiring high level of interoperation. In particular, domotics is concerned with the pervasion of technology into housing, in order to make homes more pro-active and improve the level of security and comfort of their inhabitants. In this work, we bring intelligence in...

Ensuring secure interoperation in multidomain environments based on role based access control (RBAC) has drawn considerable research works in the past. However, RBAC primarily consider static authorization decisions based on subjects’ permissions on target objects, and there is no further enforcement during the access. Recently proposed usage control (UCON) can address these requirements of acc...

The establishment of Linked Data principles has ushered in a remarkable new era of widespread semantics-based interoperation. In particular, the use of RDF, SPARQL and HTTP allow a high degree of generic tool support and lightweight composition of data sources. This rosy picture, however, mainly applies to static data. When it comes to dynamics both on-the-fly computation and the causation of s...

When one diagnostic expert system fails in solving problems alone, how can it get information available to improve itself from another similar diagnostic expert system ? This paper presents the interoperation environment to support the process. First, inference primitive structure templates have been presented to share inference structures between two diagnostic expert systems. Next, the cooper...

Peer-to-Peer (P2P) data integration combines the P2P infrastructure with traditional schema-based data integration techniques. One of the primary problems in this research area is the automation of the process of interoperation among heterogeneous data sources. To facilitate this process, metadata are used to add rich semantics to the data sources. In this paper, we propose an RDF-based layered...

Semantic interoperation and service sharing have been accepted as efficient means to facilitate collaboration among heterogonous system applications. However, extensibility and complexity are still crucial problems in supporting multi-level automatic collaborations across dynamically changed domains. In this paper, we propose the ontology based hybrid access control model. It introduces the con...

Home automation has recently gained a new momentum thanks to the ever-increasing commercial availability of domotic components. In this context, researchers are working to provide interoperation mechanisms and to add intelligence on top of them. For supporting intelligent behaviors, house modeling is an essential requirement to understand current and future house states and to possibly drive mo...
