Abstract

We present a ground-to-space quantum key distribution (QKD) mission concept and the accompanying feasibility study for the development of the low earth orbit CubeSat payload. The quantum information is carried by single photons with the binary codes represented by polarization states of the photons. Distribution of entangled photons between the ground and the satellite can be used to certify the quantum nature of the link: a guarantee that no eavesdropping can take place. By placing the entangled photon source on the ground, the space segments contains only the less complex detection system, enabling its implementation in a compact enclosure, compatible with the 12U CubeSat standard (12 dm3). This reduces the overall cost of the project, making it an ideal choice as a pathfinder for future European quantum communication satellite missions. The space segment is also more versatile than one that contains the source since it is compatible with a multiple of QKD protocols (not restricted to entangled photon schemes) and can be used in quantum physics experiments, such as the investigation of entanglement decoherence. Other possible experiments include atmospheric transmission/turbulence characterization, dark area mapping, fine pointing and tracking, and accurate clock synchronization; all crucial for future global scale quantum communication efforts., Comment: The CSUG Team: Yves Gilot, Etienne LeCoarer, Juana Rodrigo, Thierry Sequies, Vincent Borne, Guillaume Bourdarot, Alexis Christidis, Jesus Segura, Benoit Boulanger, Veronique Boutou, Mylene Bouzat, Mathieu Chabanol, Laurent Fesquet, Hassen Fourati, Michel Moulin, Jean-Michel Niot, Rodrigo Possamai Bastos, Bogdan Robu, Etienne Rolland, Sylvain Toru.

15. Assessing the Impacts of Radiation-Induced Soft Errors on Arm Cortex-M Microprocessors

Author

Benevenuti, F., Gobatto, Leonardo Reinehr, Bastos, Rodrigo Possamai, Azambuja, J. R., and Kastensmidt, F. L.

Abstract

This study investigates the impacts of radiation-induced soft errors on system-on-chips with Arm Cortex-M microprocessors. We evaluate two Cortex-M microprocessors running two applications. Regarding their use in mission- and safety-critical applications, we explore multiple scenarios, considering single, parallel, and periodic tasks, bare-metal and light operating system execution, and caches enabled and disabled. We tested two microprocessor devices under 14-MeV neutrons to draw a preliminary reliability analysis, measuring performance and reliability metrics under radiation-induced soft errors. Finally, we discuss tradeoffs between performance and reliability, providing insights into how the Arm Cortex-M microprocessor series performs in harsh environments. Results can aid designers in developing more efficient and reliable fault tolerance techniques to enable such microprocessors to operate in aerospace applications.

Abstract

Deep neural network (DNN) models are being deployed in safety-critical embedded devices for object identification, recognition, and even trajectory prediction. Optimised versions of such models, in particular the convolutional ones, are becoming increasingly common in resource-constrained edge-computing devices (e.g., sensors, drones), which typically rely on reduced memory footprint, low power budget and low-performance microprocessors. DNN models are prone to radiation-induced soft errors, and tackling their occurrence in resource-constrained devices is a mandatory and substantial challenge. While traditional replication-based soft error mitigation techniques will likely account for a reasonable performance penalty, hardware solutions are even more costly. To undertake this almost contradictory challenge, this work evaluates the efficiency of a lightweight software-based mitigation technique, called Register Allocation Technique (RAT), when applied to a convolutional neural network (CNN) model running on two commercial Arm microprocessors (i.e., Cortex-M4 and M7) under the effects of neutron radiation. Gathered results obtained from two neutron radiation campaigns suggest that RAT can reduce the number of critical faults in the CNN model running on both Arm Cortex-M microprocessors. Results also suggest that the SDC FIT rate of the RAT-hardened CNN model can be reduced in up to 83% with a runtime overhead of 32%.

Abstract

Most safety-critical edge-computing devices rely on lightweight cryptography (LWC) algorithms to provide security at minimum power and performance overhead. LWC algorithms are traditionally embedded as a hardware component, but with the advance of the Internet of Things (IoT), emerging firmware is more likely to support cryptography algorithms to comply with different security levels and industry-standards. This is the first work to present the soft error assessment of five cryptography algorithms executing in a low-power microprocessor running under neutron radiation, considering electronic code book (ECB) and counter (CTR) mode of operation implementations. Results obtained from two neutron radiation tests suggest that: ( i ) the NOEKEON algorithm gives the best relative soft error reliability, performance, power efficiency and memory footprint utilisation trade-offs between the five algorithms considering both ECB and CTR implementations, and ( ii ) cryptography solutions based on the counter mode of operation present better FIT rate for silent data corruption (SDC) and crash w.r.t. ECB implementations.

Abstract

A software technique is presented to protect commercial multi-core microprocessors against radiation-induced soft errors. Important time overheads associated with conventional software redundancy techniques limit the feasibility of advanced critical electronic systems. In our approach, redundant bare-metal threads are used, so that critical computation is distributed over the different micro-processor cores. In doing so, software redundancy can be applied to Commercial Off-The-Shelf (COTS) micro-processors without incurring high-performance penalties. The proposed technique was evaluated using a low-cost single board computer (Raspberry Pi 4) under neutron irradiation. The results showed that the Redundant Multi-Threading versions detected and recovered all the Silent Data Corruption (SDC) events, and only increased HANG sensitivity with respect to the unhardened original versions. In addition, higher Mean Work to Failure (MWTF) estimations are achieved with our bare-metal technique than with the state-of-the-art bare-metal software-based techniques that only implement temporal redundancy.

30. Learning-Based Mitigation of Soft Error Effects on Quaternion Kalman Filter Processing

Author

Kraemer Sarzi Sartori, Tarso, Fourati, Hassen, and Bastos, Rodrigo Possamai

Abstract

This article proposes a novel mitigation technique for soft error effects on the attitude estimation (AE) processing for spacecraft, especially for satellites’ application. Especially, we are focused on the soft errors that occur in space and affect, for example, the quaternion Kalman filter, running on the processor of control system of satellite, which leads to invert bits of the estimated states, miscalculations and a decreased performance. The mitigation technique detects first the presence of soft error effects on the AE algorithm output using some residuals. Then the residuals are passed to a trained machine learning (ML) models to estimate the quaternion error that will be used to correct the estimations. A supervised regression solution was proposed to correct the soft error effects, in methodology for creating a dataset for training classical ML models was developed. The results from the case-study scenario show a high reduction of soft error effects, while adding little overhead to the Kalman filter processing.

Abstract

We present a ground-to-space quantum key distribution (QKD) mission concept and the accompanying feasibility study for the development of the associated low earth orbit nanosatellite payload. The quantum information is carried by single photons with the binary codes represented by polarization states of the photons. Distribution of entangled photons between the ground and the satellite can be used to certify the quantum nature of the link: a guarantee that no eavesdropping can take place. By placing the entangled photon source on the ground, the space segments contains “only” the less complex detection system, enabling its implementation in a compact enclosure, compatible with the 12U CubeSat standard ( ${\sim}12~\mbox{dm}^{3}$ ). This reduces the overall cost of the project, making it an ideal choice as a pathfinder for future European quantum communication satellite missions. The space segment is also more versatile than one that contains the source since it is compatible with a multiple of QKD protocols (not restricted to entangled photon schemes) and can be used in quantum physics experiments, such as the investigation of entanglement decoherence. Other possible experiments include atmospheric transmission/turbulence characterization, dark area mapping, fine pointing and tracking, and accurate clock synchronization; all crucial for future global scale quantum communication efforts.

Abstract

International audience; Bulk Built-In Current Sensors (BBICS) are fault detection mechanisms embedded in integrated systems. BBICS are able to monitor anomalous transient currents like the so-called single event effects induced by radiation or even malicious injection sources. This work reviews BBICS principles and introduce new sensor architectures that improve the transient-fault detection sensitivity. In addition, a test chip is presented for the validation of the sensor concept under the laser-induced effects.
