The field of pervasive computing is in its infancy, and many of the technologies required to make it a reality are immature and high risk. The National Institute of Standards and Technology (NIST) Information Technology Laboratory (ITL) has launched a pervasive computing initiative to investigate the technical and standards roadblocks impeding the integration of emerging and existing technologies. Consistent with ITL's strategic plan, the initiative involves working with industry to develop and demonstrate test methods, reference data, tests, proof-of-concept implementations and standards to help pull the underlying technologies forward and thus help the field to mature and grow. The initiative is multi-disciplinary, takes advantage of the expertise of several divisions within ITL and creates new expertise. Areas addressed by the initiative include: information access and user interfaces, networking, software and security.

Discusses several aspects of the ETOILE (Environment for Team Organizational and Individual Learning in Emergencies) system, which may be considered to be a knowledge networked environment. These aspects are: authoring, the combination of agents and the integration of knowledge sources (databases of external simulators), the visualization of behaviour in a 3D virtual environment, the design of the human-agent interface, and the modelling, description and assessment of human behaviour. Based on our experiences in the ETOILE project, conclusions are drawn for the design of a knowledge networked environment for learning purposes.

Protocols represent the allowed interactions among communicating components. Protocols are essential in electronic commerce to constrain the behaviors of autonomous entities. Traditional representations of protocols include actions, but not their content, which limits their applicability in settings where autonomous entities must flexibly interact to handle exceptions and exploit opportunities. We develop a commitment-based representation, which provides a content to the protocols, enabling flexible execution. We show how an existing protocol can be systematically enhanced to yield a protocol that allows the given actions as well as other legal moves.

Staying aware of each other in cooperative teamwork is something we take for granted in the everyday world, even if collaboration is not continuously face-to-face, and team members frequently shift from group to individual activity during work sessions. Maintaining this intuitive fidelity of awareness, e.g. of team members working in the office next door, is, on the other hand, something that has proven particularly difficult to attain in distributed collaboration systems, where the social interaction protocol is not as well established and the means for becoming aware of the environment are far less common. The work reported in this paper is focused on workspace awareness, i.e. the "up-to-the-moment understanding of another person's interaction with a shared workspace". As opposed to the traditional understanding of shared workspaces being bounded spaces where people can see and manipulate artefacts related to their activities (documents in an office, the whiteboard in a lecture hall or assembly lines in a factory), we consider virtual mobile (team) workspaces as abstract spaces containing objects that constitute the teamwork.

For providing a privacy-enhanced access only for an appropriate user, anonymous access such as anonymous FTP is too weak because a service provider cannot know about a client, while authentication-based access control such as PKIX (Public Key Infrastructure with X.509) is too strong because ID information on a client is exposed to a service-provider. Instead, we present a new access control scheme by using SPKI (Simple Public Key Infrastructure), since an authorization certificate based on SPKI does not carry any ID information. This scheme needs additional mechanism for the server and clients such as issuing, delegating, validating, and revoking certificates. A web-based privacy-enhanced access control is designed on the basis of the proposed scheme and implemented by Java. The resulting system shows that the proposed scheme works well with a small amount of overheads being introduced into a normal web server.
为了仅为适当的用户提供增强隐私的访问，匿名访问(如匿名FTP)太弱，因为服务提供者无法了解客户端，而基于身份验证的访问控制(如PKIX(带有X.509的公钥基础设施))太强，因为客户端的ID信息暴露给服务提供者。由于基于简单公钥基础设施(SPKI)的授权证书不携带任何ID信息，因此我们提出了一种新的访问控制方案，即使用SPKI (Simple Public Key Infrastructure)。该方案需要为服务器和客户端提供额外的机制，例如颁发、委托、验证和撤销证书。在此基础上设计了一个基于web的增强隐私的访问控制，并使用Java实现。结果系统表明，所提出的方案工作良好，少量的开销被引入到一个普通的web服务器。

Distributed computing that supports cooperation among enterprises tends to be large and complex. Hence, it is not a trivial task to make enterprise computing secure and flexible. We have developed a prototype that supports flexible, secure, and recoverable enterprise computing. In this paper, we briefly describe the prototype secure enterprise application-building tool.

Although employees' expertise has long been regarded as an important asset in organizations at least on a par with capital, goods and documented information, it is only recently that automated systems to enhance the visibility and traceability of employees with particular expertise started to receive research attention. In this paper, we introduce a systematic classification of alternative architectures for a core functionality of expert finding systems, namely expertise modeling. We also analyze the advantages and disadvantages of each approach and present our hybrid solution. We discuss how this solution addresses the requirements of (I) distributed and heterogeneous organizational and personal expertise data sources and, (2) centralized access to extracted expertise information.

Nowadays, purchased software is delivered via sending CD-ROMs or downloading from the Internet. These solutions are either time-consuming or not scalable when the number of end-users becomes large. In this paper, we explore the use of multicast technology as an option for software delivery. We present a global structure for multicast software delivery and look into security issues, mainly focusing on access control in establishing a secure multicast recipient group. A communication schema between each entity in a multicast software delivery system is described in detail. We also describe briefly the implementation of our current prototype for a multicast software delivery system. Such electronic software delivery is the first phase of our ongoing project towards unattended software installation, configuration and upgrade.

NIST is an active participant in the Internet Engineering Task Force (IETF) efforts to develop Internet Protocol Security (IPsec) technology. Our ultimate goal is to expedite the rapid commercialization and ubiquitous deployment of IPsec protocols. As initial IETF IPsec specifications began to emerge, it became apparent that the availability of interoperability testing would be the critical barrier to the rapid evolution of early prototypes into commercial products. In this paper we describe the design and development of the NIST IPsec Web-based Interoperability Tester (IPsec-WIT). IPsec-WIT is an experimental test system aimed at exploiting WWW technology to provide remote interoperability testing services anytime and anywhere without requiring any distribution of test system software, or relocation of the systems under test. We conclude with a discussion of the potential future evolution of the system based on observations gained through putting our experimental system on-line and providing IPsec and Internet Key Exchange (IKE) testing services to the IETF research and development community for several months.
