The solution guarantees the consistency of the security policy and prevents any accidental or malicious update (of the local policies). The control is carried out locally (in each host) in accordance with a meta-policy that enables a distributed control to update a global security policy while satisfying global security properties. The solution is more robust in terms of fault-tolerance and resists to denial of service attacks since the solutions carries out all the control locally. Two levels of intrusion detection are proposed to guaranty the integrity and the consistency of the distributed policy. The first level (meta-level, or administration level) guarantees that each local policy evolves according to the global security properties. This level detects attacks trying inadequate alterations of the local security policies. The second level corresponds to a classical intrusion detection system. But, it can take advantages of the local policy to detect attacks that violate the security objectives. That second level enables to integrate and to adjust various classical IDS. Our approach enforces the security of large scale systems","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123185212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Virtual assembly models (VAM) are not fully integrated with other design activities, such as conceptual and detailed design, and design intent is not fully propagated to all product development activities. An assembly design (AsD) ontology can capture assembly and joining intents and can be efficiently reused in collaborative assembly development activities. Through the use of ontologies, computer systems can reason with data and information rather than just explicitly capture it. This paper presents an AsD ontology that plays as a formal, explicit specification of a shared conceptualization of assembly design and serves as a basis for a VAM for collaborative virtual prototyping and simulation (VP&S). The ontology-based VAM makes clear the relations among assembly components and form features in an AsD and provides systematized knowledge, which can be reasoned by collaboration tools. The VAM also captures design rationale including joining intent and spatial relationships. This paper discusses the role of VAM in collaborative VP&S and presents an AsD browser for virtual assembly analysis","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124461949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collaboration systems enable users at geographically distributed locations to collaborate each other. Community Grids Lab's GlobalMMCS is a Web services based, integrated videoconferencing system that allows heterogeneous clients to join the same session. Integration of mobile devices into the Web services based collaboration system will give mobility to users and heterogeneity to the system. However, there are performance limitations if we use the current SOAP approaches to integrate mobile applications with Web services based collaboration systems, especially for multimedia applications. In this paper, we propose a SOAP infoset preserving flexible representation and its specialization for mobile computing environment - handheld flexible representation (HHFR).

The experiences were gained within the framework of the collaboratory.nl project. The work is based on extended use of emerging Web services and grid security technologies, combined with concepts from the generic authentication authorization and accounting (AAA) authorisation framework. Basic CNL use cases and functional security requirements are analysed to provide motivation for the proposed job-centric security model. This model describes access control and user- and resource management. The proposed job-centric approach uses a job description as a semantic document that is created on the basis of the signed order (or business agreement). It contains all the information required to run the experiment and also to create/manage the virtual job-based associations of users and resources. The proposed trust relations analysis explains the use of trust anchors in the job-centric security model. In addition, the paper provides implementation details of using XACML and SAML for authorisation assertions and messaging, based on the current CNL implementation","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122646039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overall goal of the search algorithm is to compute sub-optimal flight trajectories for participating UAVs to minimize the combined search cost: search coverage, time, fuel usage, and communication overhead. The focus for this paper is to extend our existing search algorithm 's ability to incorporate evaluations of flight path options beyond the immediate time horizon. The paper explores the trade-offs over the additional computation cost and the reduction of the total search time. In addition to finding a set of sub-optimal UAV search paths, the search algorithm also generates a priority list of possible, search paths. The list is then used by an individual UAV to adjust its path selection to minimize a global search cost. Collectively, the selected UAV paths produce sub-optimal search patterns for a group of UAVs. The validity of the search algorithm is demonstrated using computer simulation","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125563260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an emerging area that is based on interactions enabled by Internet technology. It offers many levels of coordination, collaborative interactions and cooperation among or within organizations, and between individuals. C-commerce requires the establishment of dynamic collaborative environments over the Internet. In a collaborative environment, organizations and individuals can work together, share sensitive information, protect their privacy, and collaborate on activities and projects efficiently and effectively. This paper presents an overview of some principal concepts and definitions of c-commerce, and proposes an intelligent collaborative commerce (ICC) system architecture. The core component of the ICC architecture is a collaborative Web portal which can be used with existing e-commerce systems. We then describe each block in the collaborative Web portal component as well as the layers of Web services envisioned and their functions. The architecture can be implemented in a variety of network-centric scenarios, which form the basis for future work and further development","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133652429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
