When running these applications in an unsafe environment such as the Internet, the security concerns raised are a significant barrier to electronic commerce. In addition, these application programs (such as Web servers, mailservers, etc.) are usually too big and complex to be bug-free; trying to build security directly into these applications has proven to be very difficult. This paper demonstrates that a compartmented-mode workstation is a suitable platform to provide a secure environment that can contain most existing network applications. We describe how to wrap these applications in order to reduce the potential for a security breach without the need to rewrite the application completely. By minimizing the effort of transferring unsafe application services so that they are reasonably secure, we are able to accelerate the process of electronic commerce.","PeriodicalId":334410,"journal":{"name":"Proceedings of IEEE 6th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120948344","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}

A number of issues are coming to light about the applicability of these standards, in their present state, to the support of general multi-user VR systems. This paper pinpoints four issues that must be readdressed before large scale virtual reality systems become accessible to a larger commercial and public domain: a reduction in the effects of network delays; scalable causal event delivery; update control; and scalable reliable communication. Each of these issues is tackled through a common theme of combining wall clock and causal time-related entity behaviour, knowledge of network delays and prediction of entity behaviour, that together overcome many of the effects of network delays.","PeriodicalId":334410,"journal":{"name":"Proceedings of IEEE 6th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"568 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122930805","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 Web interface gives, a coherent and standard framework for integration of visual, audio, and text information, and for moving among elements of the educational module (local or remote). The process of developing Web-based educational modules for distance learning, often requires significant investment of time and efforts. This is sometimes hampered by a lack of resources and tools to support embedding of graphics, voice, and video clips. This paper surveys the current state of the art of Web-based instruction and presents a process model for a process-centered environment for generating Web-based course lectures. The tools surveyed include ClassNet, a tool developed at Iowa State University for managing Internet class activities, and WebCT, a tool developed at the University of British Colombia which facilitates the creation of integrated Web-base educational environments.","PeriodicalId":334410,"journal":{"name":"Proceedings of IEEE 6th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126501781","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}

Opinions were given on the types of fault tolerance (redundant paths to keys) that should be provided. The discussion invariably focused on the side-effect of key backup, which is the opening of the door to key escrow and law enforcement. Security within the Internet/intranet environment continues to be a rapid growth area. In the past year, many more security solutions have become available. The integration of security into an enterprise continues to be a balancing act between the costs of the security implementation and the value of the data that is being protected. What continues to be a goal is the development of an information infrastructure that incorporates and supports security functionality. Without this infrastructure, there can be no real secure communications outside of an enterprise.","PeriodicalId":334410,"journal":{"name":"Proceedings of IEEE 6th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126015052","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 use of agents can eliminate bottlenecks in both areas, provided that their methods of computation and communication are not overly restricted. WebVector is an agent system that combines a flexible communication model with URL-based agent identification. Within this framework, resources can be centralized to support the current web-browser security model or distributed for efficiency. Interfacing with existing software can be as simple as adding a hyperlink to a file. We concentrate on cooperative applications: uploadable active resources, flexible multicast for maintaining shared-space state, and a variety of applications from distributed computation.","PeriodicalId":334410,"journal":{"name":"Proceedings of IEEE 6th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132997194","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}
