Octopus-inspired robotic arms belong to continuum robots which are used in minimally invasive surgery or for technical system restoration in areas difficult-to-access. Continuum robot missions are bounded with their motions, whereby the motion of the robots is controlled by humans via wireless communication. In case of a lost connection, robot autonomy is required. Distributed control and distributed decision-making mechanisms based on artificial intelligence approaches can be a promising solution to achieve autonomy of technical systems and to increase their resilience. However these methods are not well investigated yet. Octopuses are the living example of natural distributed intelligence but their learning and decision-making mechanisms are also not fully investigated and understood yet. Our major interest is investigating mechanisms of Distributed Artificial Intelligence as a basis for improving resilience of complex systems. We decided to use a physical continuum robot prototype that is able to perform some basic movements for our research. The idea is to research how a technical system can be empowered to combine movements into sequences of motions by itself. For the experimental investigations a suitable physical prototype has to be selected, its motion control has to be implemented and automated. In this paper, we give an overview combining different fields of research, such as Distributed Artificial Intelligence and continuum robots based on 98 publications. We provide a detailed description of the basic motion control models of continuum robots based on the literature reviewed, discuss different aspects of autonomy and give an overview of physical prototypes of continuum robots.}, language = {en} } @misc{KabinLangendoerferDyka, author = {Kabin, Ievgen and Langend{\"o}rfer, Peter and Dyka, Zoya}, title = {Vulnerability of Atomic Patterns to Simple SCA}, series = {19th IEEE East-West Design \& Test Symposium (EWDTS 2023), (2023)}, journal = {19th IEEE East-West Design \& Test Symposium (EWDTS 2023), (2023)}, isbn = {979-8-3503-1484-7}, issn = {2472-761X}, doi = {10.1109/EWDTS59469.2023.10297074}, pages = {4}, abstract = {In this work we discuss the vulnerability of atomic pattern algorithms for elliptic curve point multiplication against simple side-channel analysis attacks using our own implementation as an example. One of the assumptions, on which the atomicity principle is based, is the indistinguishability of operations with different registers, i.e. storing of the data into two different registers cannot be distinguished if their old and new data values are the same. But before the data can be stored in a register/block, this register/block has to be addressed for storing the data. Different registers/blocks have different addresses. The key-dependent addressing of registers/blocks is an inherent feature of the binary kP algorithms and allows to reveal the key k. In our work we demonstrated it. This means that the main assumption, that addressing of different registers/blocks is an indistinguishable operation, may no longer be applied when realizing kP implementations, at least not for hardware implementations.}, language = {en} } @misc{SigourouKabinLangendoerferetal., author = {Sigourou, Alkistis and Kabin, Ievgen and Langend{\"o}rfer, Peter and Sklavos, Nicolas and Dyka, Zoya}, title = {Successful Simple Side Channel Analysis: Vulnerability of an Atomic Pattern kP Algorithm Implemented with a Constant Time Crypto Library to Simple Electromagnetic Analysis Attacks}, series = {12th Mediterranean Conference on Embedded Computing (MECO 2023), 167 (2023)}, journal = {12th Mediterranean Conference on Embedded Computing (MECO 2023), 167 (2023)}, isbn = {979-8-3503-2291-0}, issn = {2637-9511}, doi = {10.1109/MECO58584.2023.10154940}, pages = {6}, language = {en} } @misc{KabinDykaLangendoerfer, author = {Kabin, Ievgen and Dyka, Zoya and Langend{\"o}rfer, Peter}, title = {Randomized Addressing Countermeasures are Inefficient against Address-Bit SCA}, series = {IEEE International Conference on Cyber Security and Resilience (CSR 2023), 580 (2023)}, journal = {IEEE International Conference on Cyber Security and Resilience (CSR 2023), 580 (2023)}, isbn = {979-8-3503-1170-9}, doi = {10.1109/CSR57506.2023.10224968}, pages = {6}, language = {en} } @misc{AftowiczKabinDykaetal., author = {Aftowicz, Marcin and Kabin, Ievgen and Dyka, Zoya and Langend{\"o}rfer, Peter}, title = {Non-Profiled Unsupervised Horizontal Iterative Attack against Hardware Elliptic Curve Scalar Multiplication Using Machine Learning}, series = {Future Internet}, volume = {16}, journal = {Future Internet}, number = {2}, issn = {1999-5903}, doi = {10.3390/fi16020045}, abstract = {While IoT technology makes industries, cities, and homes smarter, it also opens the door to security risks.

This work presents a side channel analysis of a cryptographic hardware accelerator for the Elliptic Curve Scalar Multiplication operation, implemented in a Field-Programmable Gate Array and as an Application-Specific Integrated Circuit. The presented framework consists of initial key extraction using a state-of-the-art statistical horizontal attack and is followed by regularized Artificial Neural Networks, which take, as input, the partially incorrect key guesses from the horizontal attack and correct them iteratively. The initial correctness of the horizontal attack, measured as the fraction of correctly extracted bits of the secret key, was improved from 75\% to 98\% by applying the iterative learning.}, language = {en} } @misc{MykytynBrzozowskiDykaetal., author = {Mykytyn, Pavlo and Brzozowski, Marcin and Dyka, Zoya and Langendoerfer, Peter}, title = {A Survey on sensor- and communication-based issues of autonomous UAVs}, series = {Computer Modeling in Engineering \& Sciences}, volume = {138}, journal = {Computer Modeling in Engineering \& Sciences}, number = {2}, publisher = {Tech Science Press}, issn = {1526-1506}, doi = {10.32604/cmes.2023.029075}, pages = {1019 -- 1050}, language = {en} } @misc{AftowiczKabinDykaetal., author = {Aftowicz, Marcin and Kabin, Ievgen and Dyka, Zoya and Langend{\"o}rfer, Peter}, title = {Advantages of unsupervised learning analysis methods in single-trace SCA attacks}, series = {Microprocessors and Microsystems}, volume = {105}, journal = {Microprocessors and Microsystems}, publisher = {Elsevier BV}, issn = {0141-9331}, doi = {10.1016/j.micpro.2023.104994}, pages = {10}, language = {en} } @misc{KabinSchaeffnerSigourouetal., author = {Kabin, Ievgen and Schaeffner, Jan and Sigourou, Alkistis and Petryk, Dmytro and Dyka, Zoya and Klein, Dominik and Freud, Sven and Langend{\"o}rfer, Peter}, title = {Stealth attacks on PCBs: an experimental plausibility analysis}, series = {2024 IEEE International Conference on Cyber Security and Resilience (CSR)}, journal = {2024 IEEE International Conference on Cyber Security and Resilience (CSR)}, publisher = {IEEE}, doi = {10.1109/CSR61664.2024.10679465}, pages = {905 -- 912}, language = {en} } @misc{KabinDykaSigourouetal., author = {Kabin, Ievgen and Dyka, Zoya and Sigourou, Alkistis-Aikaterini and Langend{\"o}rfer, Peter}, title = {Static power consumption as a new side-channel analysis threat to elliptic curve cryptography implementations}, series = {2024 IEEE International Conference on Cyber Security and Resilience (CSR)}, journal = {2024 IEEE International Conference on Cyber Security and Resilience (CSR)}, publisher = {IEEE}, doi = {10.1109/CSR61664.2024.10679507}, pages = {884 -- 889}, language = {en} } @misc{MykytynBrzozowskiDykaetal., author = {Mykytyn, Pavlo and Brzozowski, Marcin and Dyka, Zoya and Langend{\"o}rfer, Peter}, title = {Towards secure and reliable heterogeneous real-time telemetry communication in autonomous UAV swarms}, series = {Poster : iCCC2024 -

Side-Channel Analysis (SCA) and Fault Injection (FI) attacks are frequently used to reveal cryptographic keys. In this paper, we present a combined SCA and laser illumination attack against an Elliptic Curve Scalar Multiplication accelerator, while using different equipment for the measurement of its power traces, i.e., we performed the measurements using a current probe from Riscure and a differential probe from Teledyne LeCroy, with an attack success of 70\% and 90\%, respectively. Our experiments showed that laser illumination increased the power consumption of the chip, especially its static power consumption, but the success of the horizontal power analysis attacks changed insignificantly. After applying 100\% of the laser beam output power and illuminating the smallest area of 143 µm² , we observed an offset of 17 mV in the measured trace. We assume that using a laser with a high laser beam power, as well as concentrating on measuring and analysing only static current, can significantly improve the attack's success. The attacks exploiting the Static Current under Laser Illumination (SCuLI attacks) are novel, and their potential has not yet been fully investigated.

Small electronic devices capable of doing that will improve the quality of life for epilepsy patients while also open new opportunities for pharmacological intervention. This paper presents a novel approach using machine learning techniques to detect seizures onset using intracranial electroencephalography (EEG) signals. The proposed approach was tested on intracranial EEG data recorded in rats with pilocarpine model of temporal lobe epilepsy. A principal component analysis was applied for feature selection before using a support vector machine for the detection of seizures. Hjorth's parameters and Daubechies discrete wavelet transform coefficients were found to be the most informative features of EEG data. We found that the support vector machine approach had a classification sensitivity of 90\% and a specificity of 74\% for detecting ictal episodes. Changing the epoch parameter from one to twenty-one seconds results in changing the redistribution of principal components' values to 10\% but does not affect the classification result. Support vector machines are accessible and convenient methods for classification that have achieved promising classification quality, and are rather lightweight compared to other machine learning methods.
