Rather than go directly to graduate school, she took a job at the Mitre Corporation where she learned that she was a … We propose a new replication algorithm, BFT, that can be used to build highly available systems that tolerate Byzantine faults. Liskov's research interests lie in programming methodology, programming languages and systems, and distributed computing. Barbara Liskov, née Barbara Jane Huberman, was born on November 7, 1939, in California. In 1971, shortly after finishing her experiments with Venus and presenting a conference paper on the topic, Liskov was urged by another attendee to consider a position at MIT. As an experimental language, Argus influenced others developers but was never widely adopted or used for deployed networked applications. Liskov's subsequent work has mainly been in the area of distributed systems, which use several computers connected by a network. Barbara Liskov, née Barbara Jane Huberman, was born on November 7, 1939, in California. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. http://www.pmg.csail.mit.edu/~liskov/ She leads the Programming Methodology Group at MIT, with a current research focus in Byzantine fault tolerance and distributed computing. Many of these, like Byzantine fault tolerance, deal with situations where a complex system fails in arbitrary ways. 2–7. Also published inProc. Google Scholar provides a simple way to broadly search for scholarly literature. Barbara Liskov received her B.A. This paper presents a new replication algorithm that has desirable performance properties; we use a special kind of timestamp called a viewstamp to detect lost information. We introduce the decentralized label model, a new label model for control of information flow in systems with mutual distrust and decentralized authority. These concepts are a foundation of object-oriented programming used in modern computer languages such as Java and C#, although many other features of modern object oriented programming are missing from this early language.

Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Protecting privacy using the decentralized label model, Foundations of Intrusion Tolerant Systems…. Proactive recovery in a Byzantine-fault-tolerant system. She had not known that the principle had borne her name for years in the community. Article on Professor Liskov in Technology Review (MIT), This paper describes an asynchronous state-machine replication system that tolerates Byzantine faults, which can be caused by malicious attacks or software errors, and it performs well because it uses symmetric rather than public-key cryptography for authentication. We introduce the decentralized label model, a new label model for control of information flow in systems with mutual distrust and decentralized authority. The Venus operating system was a small timesharing system for the Venus machine used to experiment with how different architectures helped or hindered this process. Search across a wide variety of disciplines and sources: articles, theses, books, abstracts and court opinions. Her contributions have influenced advanced system developments and set a standard for clarity and usefulness. "Her pioneering research has made her one of the world's leading Barbara Liskov (born November 7, 1939 as Barbara Jane Huberman) is an American computer scientist who is an Institute Professor at the Massachusetts Institute of Technology and Ford Professor of Engineering in its School of Engineering 's electrical engineering and computer science department. She earned her BA in mathematics at the University of California, Berkeley in 1961. Viewstamped Replication: A New Primary Copy Method to Support Highly-Available Distributed Systems. PATRICK M. HANRAHAN. "Barbara is revered in the MIT community for her role as scholar, mentor and leader," said MIT President Susan Hockfield. Returning to California to do graduate work at Stanford, she was given financial support in John McCarthy’s lab partly because her earlier work on natural language translation was in the general area of artificial intelligence. She has supervised the research programs of more than twenty PhD students and large numbers of MSc students. 32-G924 Barbara Liskov is an Institute Professor and head of the Programming Methodology Group.
