1. A Comprehensive Review of Adversarial Attacks on Machine Learning

Author

Ahmed, Syed Quiser, Ganesh, Bharathi Vokkaliga, Kumar, Sathyanarayana Sampath, Mishra, Prakhar, Anand, Ravi, and Akurathi, Bhanuteja

Subjects
Computer Science - Cryptography and Security
Abstract

This research provides a comprehensive overview of adversarial attacks on AI and ML models, exploring various attack types, techniques, and their potential harms. We also delve into the business implications, mitigation strategies, and future research directions. To gain practical insights, we employ the Adversarial Robustness Toolbox (ART) [1] library to simulate these attacks on real-world use cases, such as self-driving cars. Our goal is to inform practitioners and researchers about the challenges and opportunities in defending AI systems against adversarial threats. By providing a comprehensive comparison of different attack methods, we aim to contribute to the development of more robust and secure AI systems.

10. Linear Cryptanalysis through the Lens of Clauser-Horne-Shimony-Holt Game

Author

Subjects
Quantum Physics
Abstract

Application of CHSH game in Linear Cryptanalysis is presented. Till date, the known usage of CHSH game in Quantum Cryptology is to verify the device independence of the protocols. We observed that the classical symmetric ciphers having the bias equal to 0:25 can be improved to 0:35 exploiting the game which indicates clear improvement over existing Linear and Differential cryptanalysis. In the present initiative, we showed the application of the game in linear cryptanalysis on a lightweight cipher named SIMON. However, the approach can be extended to Differential cryptanalysis too. This observation opens a new direction of research in quantum cryptography., Comment: 8 pages, 5 figures, 2 tables

15. Grover on SIMON

Abstract

For any symmetric key cryptosystem with $n$-bit secret key, the key can be recovered in $O(2^{n/2})$ exploiting Grover search algorithm, resulting in the effective key length to be half. In this direction, subsequent work has been done on AES and some other block ciphers. On the other hand, lightweight ciphers like SIMON was left unexplored. In this backdrop, we present Grover's search algorithm on all the variants of SIMON and enumerate the quantum resources to implement such attack in terms of NOT, CNOT and Toffoli gates. We also provide the T-depth of the circuits and the number of qubits required for the attack. We show that the number of qubits required for implementing Grover on SIMON $2n/mn$ is $O(2nr+mn)$, where $r$ is the number of chosen plaintext-cipher text pairs. We run a reduced version of SIMON in IBMQ quantum simulator and the 14-qubits processor as well. We found that where simulation supports theory, the actual implementation is far from the reality due to the infidelity of the gates and short decoherence time of the qubits. The complete codes for all version of SIMON have also been presented.

28. Therapeutic Effect of Evenamide, a Glutamate Inhibitor, in Patients With Treatment-Resistant Schizophrenia (TRS): Final, 1-Year Results From a Phase 2, Open-Label, Rater-Blinded, Randomized, International Clinical Trial.

Abstract

The results from a pilot, 1-year, randomized, open-label, add-on treatment study in treatment-resistant schizophrenia (TRS) with evenamide, a glutamate modulator, were not associated with any safety abnormalities at all doses (7.5-30 mg bid), with a high retention rate even at 6-month (~85%), and 1-year (~75%), and the absence of psychotic relapses during the 1-year treatment period. Overall, treatment with evenamide showed a gradual, sustained, and clinically important improvement up to 1 year in all efficacy measures (eg, PANSS mean change ~ −20%; CGI-S mean change ~ −1.0). In addition, compared to the results at Week 6, the responder rates generally more than doubled at 1-year (PANSS "≥20% improvement from baseline" = ~45%; CGI-S "2-category of improvement" = ~25%; CGI-C "much improved" = ~40%). These results, rarely replicated in other trials in TRS, support the use of evenamide as an add-on treatment in patients who are not benefiting from their current first- or second-generation antipsychotic medication.

38. A novel 13‐level switched‐capacitor step‐up inverter with reduced component count.

Abstract

Summary: This article presents a switched‐capacitor‐based 13‐level inverter that exhibits step‐up property. The suggested converter makes use of a single DC source, 12 switches, three capacitors, and two diodes to accomplish the goal of producing a 13‐level output voltage while simultaneously achieving a boosting factor of six. Notably, inherent voltage balancing is attained for a wide variety of load types without the need of complex control methods or additional circuitry. In addition to this, the paper presents a comprehensive study of the power losses that occur across the different components of the converter. Multiple aspects of a topology's performance are taken into account during a comparison analysis with recent topologies that have a single and double DC sources connected to the input. The investigation incorporates simulations with both inductive and resistive loads. In order to validate that the proposed converter is effective, a prototype is built in the laboratory. The practicality of the suggested topology is shown by the collection of experimental result acquired under different loading situations. These findings include dynamic fluctuations in load and modulation indices. [ABSTRACT FROM AUTHOR]

Abstract

Summary This paper describes a novel seven‐level (7L) inverter. The suggested topology offers a 7L output voltage and a threefold gain by using proper capacitor values. The suggested topology reduces the spike current induced by the capacitor by the use of a resonant inductor. The suggested inverter's performance under various loads and situations is compared with those found in existing literature. The simulation findings confirm the system's strong performance in terms of component count, control circuit simplicity, and possible cost reductions, while retaining similar or enhanced performance metrics as compared with the aforementioned topologies. A laboratory setup is used to validate the feasibility of the suggested topology and provide solid evidence of its effectiveness. Furthermore, discussions about the possible uses of this structure in energy conversion are conducted. [ABSTRACT FROM AUTHOR]
