3DeformRS: Certifying Spatial Deformations on Point Clouds
No full textPublisher Copyright: © 2022 IEEE.3D computer vision models are commonly used in security-critical applications such as autonomous driving and surgical robotics. Emerging concerns over the robustness of these models against real-world deformations must be addressed practically and reliably. In this work, we propose 3DeformRS, a method to certify the robustness of point cloud Deep Neural Networks (DNNs) against real-world deformations. We developed 3DeformRS by building upon recent work that generalized Randomized Smoothing (RS) from pixel-intensity perturbations to vector-field deformations. In particular, we specialized RS to certify DNNs against parameterized deformations (e.g. rotation, twisting), while enjoying practical computational costs. We leverage the virtues of 3DeformRS to conduct a comprehensive empirical study on the certified robustness of four representative point cloud DNNs on two datasets and against seven different deformations. Compared to previous approaches for certifying point cloud DNNs, 3DeformRS is fast, scales well with point cloud size, and provides comparable-to-better certificates. For instance, when certifying a plain PointNet against a 3° z-rotation on 1024-point clouds, 3DeformRS grants a certificate 3× larger and 20× faster than previous work 11Code:https://github.com/gaperezsa/3DeformRS.Acknowledgements.

Naming Amplified Tests Based on Improved Coverage
No full textTest amplification generates new test cases that improve the coverage of an existing test suite. To convince developers to integrate these new test cases into their test suite, it is crucial to convey the behavior and the improvement in coverage that the amplified test case provides. In this paper, we present NATIC, an approach to generate names for amplified test cases based on the methods they additionally cover, compared to the existing test suite. In a survey among 16 participants with a background in Computer Science, we show that the test names generated by NATIC are valued similarly to names written by experts. According to the participants, the names generated by NATIC outperform expert-written names with respect to informing about coverage improvement, but lack in conveying a test's behavior. Finally, we discuss how a restriction to two mentioned methods per name would improve the understandability of the test names generated by NATIC.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Software EngineeringElectrical Engineering, Mathematics and Computer Scienc

Adaptive physical layer security using code bank of sequences for CDMA
No full textWireless security is an important concern in todays technological world. Wireless devices are used to access data and private applications. From broadband to Wi-Fi, 3G to LTE Advanced, WiMAX to satellite communication every network demands on-the-air security from attacks. Tapping or Jamming attacks leak the secret data, while Service Disruption Attacks affecting QoS (Quality of Service) are relatively easy to perform. In CDMA, the channel and antenna dependent attacks are quite critical to avoid because of its wide bandwidth usage. The critical exchange of time and frequency parameters makes the physical layer elements vulnerable to security related attacks. In order to enable data security and secrecy, there is need of signal protection at the physical layer of CDMA system. Gold codes, M-sequences, OVSF and De-Bruijn sequences were used individually in wireless systems for scrambling purposes in previous proposals. These codes have their own advantages and disadvantages, when channel bandwidth and noise conditions change. This paper proposes a system which would select scrambling codes from a bank of all these mentioned codes depending upon the Signal to Noise Ratio (SNR) or Channel State Information (CSI). This code bank technique is shown as a highly practical solution in selection of proper code for mitigation of attacks and hence, to provide security at the physical layer of CDMA
Proposta de arquitetura de comunicação para sistemas embarcados baseada no protocolo Publisher/Subscriber
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Engenharia ElétricaEsta dissertação apresenta uma proposta de arquitetura denominada Distributed Objectbased Architecture for Controlling Autonomous Vehicles - DOCAS. DOCAS é baseada no protocolo Publisher/Subscriber, e temsua utilização voltada para o controle de veículos autônomos. Um sistema distribuído baseado no protocolo Publisher/Subscriber tem como características o desacoplamento entre seus componentes, comunicações anônimas com mensagens curtas e identificadas por conteúdo e também comunicações muitos-para-muitos. Com a utilização da arquitetura proposta, torna-se possível realizar comunicação através de diferentes protocolos de forma anônima, ou seja, pode-se constituir um sistema que integra vários protocolos de rede para interligar diferentes plataformas de hardware (nodos da rede) interagindo através de eventos. Além disso, a arquitetura proposta permite programar, de uma forma simplificada, a comunicação entre os elementos envolvidos na aplicação. Esta proposta também discute alternativas para representar o problema num nível de abstração mais elevado. Investigam-se as características de um sistema de controle dessa natureza, levantando-se questões de modelagem que contemplem tais características. Para validar e exemplificar a arquitetura proposta é mostrado um estudo de caso voltado para o controle de um veículo autônomo
