Efficient Authenticated Data Structures for Graph Connectivity and Geometric Search Problems [article]

Michael T. Goodrich, Roberto Tamassia, Nikos Triandopoulos
2009 arXiv   pre-print
This allows the design of new, efficient authenticated data structures for fundamental problems on networks, such as path and connectivity queries over graphs, and complex queries on two-dimensional geometric  ...  Authenticated data structures provide cryptographic proofs that their answers are as accurate as the author intended, even if the data structure is being controlled by a remote untrusted host.  ...  We would like to thank Robert Cohen for contributing to the results of Section 4 and for coauthoring a preliminary version of this paper [33] .  ...

Model-Based Stochastic Simulation of P2P VoIP Using Graph Transformation System [chapter]

Ajab Khan, Reiko Heckel, Paolo Torrini, István Ráth
2010 Lecture Notes in Computer Science  
We propose an approach to modelling and simulation of P2P systems based on graph transformations, a visual rule based formalism that has recently been supported by facilities for stochastic modelling and  ...  Focussing on P2P VoIP applications such as Skype, we model alternative solutions to the problem of selection of and connection to super nodes (i.e., the peers acting as servers in the network) and evaluate  ...  Graph transformation can not only model these networks but it also support a number of validation and verification techniques.  ...

SybilShield: An agent-aided social network-based Sybil defense among multiple communities

Lu Shi, Shucheng Yu, Wenjing Lou, Y. Thomas Hou
2013 2013 Proceedings IEEE INFOCOM  
These solutions are mostly built on the assumption that the social network graph can be partitioned into two loosely linked regions -a tightly connected non-Sybil region and a Sybil region.  ...  Our scheme leverages the sociological property that the number of cutting edges between a non-Sybil community and a Sybil community, which represent human-established trust relationships, is much smaller  ...  Although the Sybil acceptance rate rises a little, the tradeoff between greatly reduced false positive rate and Sybil acceptance rate is acceptable.  ...

TESTOR: A Modular Tool for On-the-Fly Conformance Test Case Generation [chapter]

Lina Marsso, Radu Mateescu, Wendelin Serwe
2018 Lecture Notes in Computer Science  
Compared to the existing tool TGV, TESTOR has a more modular architecture, based on generic graph transformation components, is capable of extracting a test case completely on the fly, and enables a more  ...  Concretely, given a formal specification of a system and a test purpose, TESTOR automatically generates test cases, which assess using black box testing techniques the conformance to the specification  ...  We are grateful to Alexander Graf-Brill and Holger Hermanns for providing us with the model and test purposes of their EnergyBus case study.  ...

Keystroke Dynamics Authentication Using a Small Number of Samples

Jan Čapek, Miloslav Hub
2020 E & M Ekonomie a Management  
The verification of a person's identity is very important in today's information society, especially in e-commerce systems and directly affects user account management and administration.  ...  The solution is a two-factor authentication where a user needs to know the right password and at the same time, he must write this password in the correct way.  ...  We think that a much more convenient tool for comparing different methods is the Detection Error Tradeoff (DET) graph than only one point on this graph.  ...

Discovering Empirical Theories of Modular Software Systems. An Algebraic Approach [chapter]

Nicola Angius, Petros Stefaneas
2016 Computing and Philosophy  
Empirical theories of computational systems are required to be modular, as modular are most software verification and testing activities.  ...  Both deductive top-down and inductive bottom-up approaches in the discovery of semantic software theories are refused to argue in favour of the abductive process of hypothesising and refining models at  ...  This research has been co-financed by the European Union (European Social Fund-ESF) and Greek national funds through the Operational Program Education and Lifelong Learning of the National Strategic Reference  ...

CEV Framework: A Central Bank Digital Currency Evaluation and Verification Framework With a Focus on Consensus Algorithms and Operating Architectures

Si Yuan Jin, Yong Xia
2022 IEEE Access  
We propose a Central Bank Digital Currency Evaluation and Verification (CEV) Framework for recommending and verifying technical solutions in the central bank digital currency (CBDC) system.  ...  We demonstrate two sub-frameworks: an evaluation sub-framework that provides consensus algorithm and operating architecture solutions and a verification sub-framework that validates the proposed solutions  ...  A tradeoff [6] exists between CBDC system features that we cannot achieve excellent performance, security, and privacy simultaneously.  ...

Sequential decision models for expert system optimization

V.S. Mookerjee, M.V. Mannino
1997 IEEE Transactions on Knowledge and Data Engineering  
Sequential decision models are an important element of expert system optimization when the cost or time to collect inputs is significant and inputs are not known until the system operates.  ...  A wide variety of sequential decision models are discussed in this taxonomy.  ...  The noise in the input can be reduced by verification or resampling resulting in a cost-quality tradeoff for the information.  ...

Footprint: Detecting Sybil Attacks in Urban Vehicular Networks

Shan Chang, Yong Qi, Hongzi Zhu, Jizhong Zhao, Xuemin Shen
2012 IEEE Transactions on Parallel and Distributed Systems  
Rigorous security analysis and extensive trace-driven simulations demonstrate the efficacy of Footprint.  ...  In urban vehicular networks, where privacy, especially the location privacy of anonymous vehicles is highly concerned, anonymous verification of vehicles is indispensable.  ...  Thus, there exists a small "cut" on the graph of trust relationship between the forged identities and the real ones.  ...

Lightweight, pollution-attack resistant multicast authentication scheme

Ya-Jeng Lin, Shiuhpyng Shieh, Warren W. Lin
2006 Proceedings of the 2006 ACM Symposium on Information, computer and communications security - ASIACCS '06  
However, the use of erasure codes introduces pollution attack, an attack in which the adversary injects packets to disrupt the erasure decoding procedure and consequently denies the authentication service  ...  to the receiver.  ...  After verifying the signature, a receiver can consider this block of packets authentic. Signature amortization makes a tradeoff between security and computation overhead.  ...
