Abstract

Digital management of multiple robust identities is a crucial issue in developing the next generation of distributed applications. Our daily activities increasingly rely on remote resources and services - specifically, on interactions between different, remotely located parties. Because these parties might (and sometimes should) know little about each other, digital identities - electronic representations of individuals' or organizations' sensitive information - help introduce them to each other and control the amount of information transferred. In its broadest sense, identity management encompasses definitions and life-cycle management for digital identities and profiles, as well as environments for exchanging and validating such information. Digital identity management - especially support for identity dependability and multiplicity - is crucial for building and maintaining trust relationships in today's globally interconnected society. We investigate the problems inherent in identity management, emphasizing the requirements for multiplicity and dependability. We enable a new generation of advanced MDDI services on the global information infrastructure.

Adjie-Winoto, W., Schwartz, E., Balakrishnan, H., and Lilley, J. 2000. The design and implementation of an intentional naming system. SIGOPS Oper. Syst. Rev. 34, 2 (Apr. 2000), 22. DOI= http://doi.acm.org/10.1145/346152.346192

Abstract

This paper presents the design and implementation of the Intentional Naming System (INS), a resource discovery and service location system for dynamic and mobile networks of devices and computers. Such environments require a naming system that is (i) expressive, to describe and make requests based on specific properties of services, (ii) responsive, to track changes due to mobility and performance, (iii) robust, to handle failures, and (iv) easily configurable. INS uses a simple language based on attributes and values for its names. Applications use the language to describe what they are looking for (i.e., their intent), not where to find things (i.e., not hostnames). INS implements a late binding mechanism that integrates name resolution and message routing, enabling clients to continue communicating with end-nodes even if the name-to-address mappings change while a session is in progress. INS resolvers self-configure to form an application-level overlay network, which they use to discover new services, perform late binding, and maintain weak consistency of names using soft-state name exchanges and updates. We analyze the performance of the INS algorithms and protocols, present measurements of a Java-based implementation, and describe three applications we have implemented that demonstrate the feasibility and utility of INS.

Abstract

So far remote access solutions for residential services require modifications to clients. In addition, remote access adds complexity to the client application. We propose here a solution that decouples remote access from the client itself with an entity that creates virtual instances of remote services in a local network. Thereby, clients will be able to discover the virtual instance and use it. Moreover, client applications do not need to distinguish between local and remote services hence reducing complexity.
