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{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. With the right equipment and physical access to the devices, the attacker can leverage side-channel information, like timing, power consumption, or electromagnetic emanation, to compromise cryptographic operations and extract the secret key. 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{NatarovSudakovDykaetal., author = {Natarov, Roman and Sudakov, Oleksandr and Dyka, Zoya and Kabin, Ievgen and Maksymyuk, O. and Iegorova, O. and Krishtal, Oleg A. and Langend{\"o}rfer, Peter}, title = {Resilience Aspects in Distributed Wireless Electroencephalographic Sampling}, series = {2020 9th Mediterranean Conference on Embedded Computing (MECO)}, journal = {2020 9th Mediterranean Conference on Embedded Computing (MECO)}, isbn = {978-1-7281-6949-1}, doi = {10.1109/MECO49872.2020.9134157}, pages = {7}, language = {en} } @misc{NatarovDykaBohovyketal., author = {Natarov, Roman and Dyka, Zoya and Bohovyk, R. and Fedoriuk, M. and Isaev, Dmytro S. and Sudakov, Oleksandr and Maksymyuk, O. and Krishtal, Oleg A. and Langend{\"o}rfer, Peter}, title = {Artefacts in EEG Signals Epileptic Seizure Prediction using Edge Devices}, series = {International Conference on Cyber-Physical Systems and Internet-of-Things (CPS \& IoT 2020)}, journal = {International Conference on Cyber-Physical Systems and Internet-of-Things (CPS \& IoT 2020)}, isbn = {978-1-7281-6949-1}, doi = {10.1109/MECO49872.2020.9134076}, pages = {3}, language = {en} } @misc{MykytynKabinDykaetal., author = {Mykytyn, Pavlo and Kabin, Ievgen and Dyka, Zoya and Langend{\"o}rfer, Peter}, title = {Ensuring a Secure Communication Between a GCS and a UAV via the MAVlink Protocol}, series = {Proc. 33rd Crypto-Day Matters 2021, (2021)}, journal = {Proc. 33rd Crypto-Day Matters 2021, (2021)}, doi = {10.18420/cdm-2021-33-21}, pages = {2}, language = {en} } @misc{MykytynBrzozowskiDykaetal., author = {Mykytyn, Pavlo and Brzozowski, Marcin and Dyka, Zoya and Langend{\"o}rfer, Peter}, title = {GPS-Spoofing Attack Detection Mechanism for UAV Swarms}, series = {12th Mediterranean Conference on Embedded Computing (MECO)}, journal = {12th Mediterranean Conference on Embedded Computing (MECO)}, isbn = {979-8-3503-2290-3}, issn = {2637-9511}, doi = {10.1109/MECO58584.2023.10154998}, pages = {8}, language = {en} }
