Authentication for distributed systems

A number of protocols used to authenticate users, hosts and processes are described. The three main types of authentication in a distributed computing system-message content authentication, message origin authentication, and general identit...

Distributed systems: Concepts and design

Authentication in distributed systems

Security of distributed systems is a topic of growing importance.The security breaches of the last few years (internet worm .... ) have demonstrated the need for additional research in this area.One important aspect of security is authentic...

Virtual Time and Global States of Distributed Systems

A distributed system can be characterized by the fact that the global state is distributed and that a common time base does not exist. However, the notion of time is an important concept in every day life of our decentralized "real world" a...

Distributed System Design

Future requirements for computing speed, system reliability, and cost-effectiveness entail the development of alternative computers to replace the traditional von Neumann organization. As computing networks come into being, one of the lates...

The V distributed system

The V distributed System was developed at Stanford University as part of a research project to explore issues in distributed systems. Aspects of the design suggest important directions for the design of future operating systems and communic...

Evaluating the scalability of distributed systems

Many distributed systems must be scalable, meaning that they must be economically deployable in a wide range of sizes and configurations. This paper presents a scalability metric based on cost-effectiveness, where the effectiveness is a fun...

Time, clocks, and the ordering of events in a distributed system

The concept of one event happening before another in a distributed system is examined, and is shown to define a partial ordering of the events. A distributed algorithm is given for synchronizing a system of logical clocks which can be used ...

Trust Management in Distributed Systems

Distributed systems such as the Internet, peer-to-peer networks, and mobile ad hoc networks involve numerous entities, many of which haven't previously interacted. Trust management can help minimize risk and ensure the network activity of b...

Distributed systems

Growth of distributed systems has attained unstoppable momentum. If we better understood how to think about, analyze, and design distributed systems, we could direct their implementation with more confidence....

Constructing distributed systems in Conic

The Conic environment provides a language-based approach to the building of distributed systems which combines the simplicity and safety of a language approach with the flexibility and accessibility of an operating systems approach. It prov...

A calculus for access control in distributed systems

We study some of the concepts, protocols, and algorithms for access control in distributed systems, from a logical perspective. We account for how a principal may come to believe that another principal is making a request, either on his own...

Time, clocks, and the ordering of events in a distributed system

The concept of one event happening before another in a distributed system is examined, and is shown to define a partial ordering of the events. A distributed algorithm is given for synchronizing a system of logical clocks which can be used ...

Checkpointing and Rollback-Recovery for Distributed Systems

We consider the problem of bringing a distributed system to a consistent state after transient failures. We address the two components of this problem by describing a distributed algorithm to create consistent checkpoints, as well as a roll...

A general theory of glacier surges

We present the first general theory of glacier surging that includes both temperate and polythermal glacier surges, based on coupled mass and enthalpy budgets. Enthalpy (in the form of thermal energy and water) is gained at the glacier bed ...

Relationship between grief and coping strategies among nurses dealing with patient deaths: a descriptive, cross-sectional, correlational study

Abstract Background Nurses often face significant emotional distress and grief when dealing with patient deaths, especially in acute hospital settings. Despite extensive literature offering guidance on nursing practices for providing optima...

Voltage Stability and Power Sharing Control of Distributed Generation Units in DC Microgrids

Advancements in power conversion efficiency and the growing prevalence of DC loads worldwide have underscored the importance of DC microgrids in modern energy systems. Addressing the challenges of power-sharing and voltage stability in thes...

Psychometric facets of Antifragility: Tolerance of Ambiguity, Hardiness, and Growth

This paper considers the issues, which are concerned with a new concept of antifragility. Quite recently, considerable attention has been paid to the concept of antifragility. Antifragility gains a special importance in studying psychologic...

Guiding the Self-Organization of Cyber-Physical Systems

Self-organization offers a promising approach for designing adaptive systems. Given the inherent complexity of most cyber-physical systems, adaptivity is desired, as predictability is limited. Here I summarize different concepts and approac...

Empowering Sustainability: The Crucial Role of IoT-Enabled Distributed Learning Systems in Reducing Carbon Footprints

Electrical energy plays a pivotal role in modern society by powering homes, industries, and transportation systems. However, the production of electricity is associated with significant carbon emissions, primarily from fossil fuel-based pow...
