La notion de ferroélasticité, récemment introduite en physique est présentée et expliquée. Les caractéristiques des matériaux ferroélectriques et de leurs transitions de phase sont étudiées du point de vue cristallographique et thermodynamique. L’intérêt pratique de ces matériaux est démontré pour des applications relatives au traitement optique de l’information. The concept ferroélasticiting, recently introduced in physics, is presented and explained. The main features of ferroelastic materials and of their phase transitions are studied through their crystallographic and thermodynamical aspects. The practical use of these materials is pointed out for applications in the fields of optical data processing.

With the extensive application of deep learning (DL) algorithms in recent years, e.g., for detecting Android malware or vulnerable source code, artificial intelligence (AI) and machine learning (ML) are increasingly becoming essential in the development of cybersecurity solutions. However, sharing the same fundamental limitation with other DL application domains, such as computer vision (CV) and natural language processing (NLP), AI-based cybersecurity solutions are incapable of justifying the results (ranging from detection and prediction to reasoning and decision-making) and making them understandable to humans. Consequently, explainable AI (XAI) has emerged as a paramount topic addressing the related challenges of making AI models explainable or interpretable to human users. It is particularly relevant in cybersecurity domain, in that XAI may allow security operators, who are overwhelmed with tens of thousands of security alerts per day (most of which are false positives), to better assess the potential threats and reduce alert fatigue. We conduct an extensive literature review on the intersection between XAI and cybersecurity. Particularly, we investigate the existing literature from two perspectives: the applications of XAI to cybersecurity (e.g., intrusion detection, malware classification), and the security of XAI (e.g., attacks on XAI pipelines, potential countermeasures). We characterize the security of XAI with several security properties that have been discussed in the literature. We also formulate open questions that are either unanswered or insufficiently addressed in the literature, and discuss future directions of research.
