3 Forsyte papers accepted at CAV 2019
Thursday, Apr 18, 2019

Papers co-authored by Jure Kukovec, Marijana Lazić, and Josef Widder were accepted to be presented at the 31st International Conference on Computer-Aided Verification. Title: Reachability Analysis for AWS-based NetworksAuthors: J. Backes, S. Bayless, B. Cook, C. Dodge, A. Gacek, A.J. Hu, T. Kahsai, B. Kocik, E. Kotelnikov, J. Kukovec, S. McLaughlin, J. Reed, N. Rungta, J. Sizemore, M. Stalzer, P. Srinivasan, P. Subotić, C. Varming, B. Whaley, Y. WuAbstract: Cloud services provide the ability to provision virtual networked infrastructure on demand over the internet. The rapid growth of these virtually provisioned cloud networks has increased the demand for automated reasoning tools capable of identifying misconfigurations or security vulnerabilities. This type of automation gives customers the assurance they need to deploy sensitive workloads. It can also dramatically reduce the cost and time-to-market for regulated customers looking to establish compliance certification for cloud-based applications. In this industrial case-study, we describe a new network reachability reasoning tool, called Tiros, that uses off-the-shelf automated theorem proving tools to fill this need. Tiros is the foundation of a recently introduced network security analysis feature in the Amazon Inspector service now available to millions of customers building applications in the cloud.Tiros is also used within Amazon Web Services (AWS) to automate the checking of compliance certification and adherence to security invariants for many AWS services that build on existing AWS networking features. Title: Verification of Threshold-based Distributed Algorithms by Decomposition to Decidable LogicsAuthors: Idan Berkovits, Marijana Lazić, Giuliano Lossa, Oded Padon and Sharon ShohamAbstract: Verification of fault-tolerant distributed protocols is an immensely difficult task. Often, in these protocols, thresholds on set cardinalities are used both in the process code and in its correctness proof, e.g., a process can perform an action only if it has received an acknowledgment from at least half of its peers. Verification of threshold-based protocols is extremely challenging as it involves two kinds of reasoning: first-order reasoning about the unbounded state of the protocol, together with reasoning about sets and cardinalities. In this work, we develop a new methodology for decomposing the verification task of such protocols into two decidable logics: EPR and BAPA. Our key insight is that such protocols use thresholds in a restricted way as a mean to obtain certain properties of “intersection” between sets. We define a language for expressing such properties, and present two translations: to EPR and BAPA. The EPR translation allows us to verify the protocol while assuming these properties, and the BAPA translation allows us to verify the correctness of the properties. We further develop an algorithm for automatically generating the properties needed for verifying a given protocol, facilitating a fully automated deductive verification. Using this technique we have verified several challenging benchmarks, including Byzantine one-step consensus, hybrid reliable broadcast and fast Byzantine Paxos. Title: Communication-closed asynchronous protocolsAuthors: Andrei Damian, Cezara Dragoi, Alexandru Militaru and Josef Widder.Abstract: The verification of asynchronous fault-tolerant distributedsystems is challenging due to the exponential number ofinterleavings, unbounded message buffers, and networkfailures (e.g., processes crash or message loss). We propose amethod that, for a class of protocols, reduces the verificationof asynchronous fault-tolerant protocols to the verification of around-based synchronous ones. Synchronous protocols are easierto verify due to fewer interleavings, bounded message buffersetc. We implemented our reduction method and applied it toseveral state machine replication and consensus algorithms, amongwhich are Multi-Paxos and Chandra&Toueg’s atomic broadcast. Theresulting synchronous protocols are verified using existingdeductive verification methods.Preliminary version: https://hal.inria.fr/hal-01991415v1

Der gute Ruf der TU Wien wird zum Fluch für das Studium, denn auf 52 habilitierte Professoren kommen fast 7000 Studierende; ein solches Verhältnis wäre bei anderen international führenden Universitäten undenkbar. Alle wissen, dass Mangelwirtschaft an Universitäten dem Wissenschafts- und Wirtschaftsstandort schadet, die Innovationskraft unserer Gesellschaft untergräbt und den wissenschaftlichen Nachwuchs ins Ausland treibt.

Goals: The goal is to get acquainted with the theory of coalgebra and its use in computer science. Also, along the way, the students will get to know some category theory notions that are needed for basic constructions and results in coalgebra. The course is meant for computer science students (possibly also some mathematics students) interested in computer science theory. If you are a student interested in formal methods, concurrency theory, and/or automata, and/or you always wondered what is category theory good for, then this may be the right course for you. Content: The theory of coalgebra is a relatively recent (20 years old) unifying theory at the abstract end of formal methods. It is a (one could say “the”) theory of dynamic systems, of states and observations. Coalgebras allow for a uniform treatment of many different types of automata (e.g. deterministic, nondeterministic, probabilistic, and weighted), their behavior, and their corresponding modal logics. These topics will be covered within the course. How students are evaluated:The evaluation will depend on presented papers and the examination at the end of term.

Upcoming Course: Johannes Fürnkranz
Thursday, Feb 23, 2012

Johannes Fürnkranz from TU Darmstadt will be visiting as a guest lecturer for the course: VO Inductive Rule Learning Mon 08:30 – 13:00 12.03.2012 seminar room Gödel Tue 08:30 – 13:00 13.03.2012 seminar room Gödel Mon 12:30 – 17:00 19.03.2012 seminar room Gödel Mon 08:30 – 13:00 26.03.2012 seminar roomGödel Tue 08:30 – 13:00 27.03.2012 seminar room Gödel Registration and further details in TISS. Aim of the course: The goal of this course to familiarize the student with fundamental concepts of machine learning in general and inductive rule learning in particular. It will focus both on a predictive setting, where the goal is to learn a set of rules that collectively make a prediction, and a descriptive setting, where the goal is to learn a set of rules that collectively explain the data. The learning techniques will be first illustrated for concept learning tasks in propositional logic, but later also extended to first-order logic as well as to structured prediction tasks. There are no prerequisites except for basic knowledge about algorithms. The course is thus not only suited for computer science students but for all students that have a strong interest in machine learning in data analysis. Content: Rules – the clearest, most explored and best understood form of knowledge representation – are particularly important for data mining, because they offer the best tradeoff between human and machine understandability. This course will present algorithms for automated rule learning and discovery as investigated in classical machine learning and modern data mining. We will start with algorithms for learning single rules in propositional logic, move on to learning rule sets with the covering or separate-and-conquer algorithm, inductive logic programming algorithms for learning rules in first-order logic, and discuss approaches that allow to make predictions in structured output spaces. Elementary data mining algorithms such as association rule discovery will also be covered, as well as essential concepts of machine learning and data mining. It is thus suitable as a first introduction into these research areas. Most of the course will follow the book “Foundations of Rule Learning” that will appear in Springer-Verlag in early 2012. http://www.amazon.de/Rule-Learning-Essentials-Relational-Technologies/dp/3540751963
