Augmenting white cane reliability using smart glove for visually impaired people
No full textThe independent mobility problem of visually impaired people has been an active research topic in biomedical engineering: although many smart tools have been proposed, traditional tools (e.g., the white cane) continue to play a prominent role. In this paper a low cost smart glove is presented: the key idea is to minimize the impact in using it by combining the traditional tools with a technological device able to improve the movement performance of the visually impaired people

A low cost smart glove for visually impaired people mobility
No full textDegradation of the visual system reduces the mobility of a person that relies only on his sense of touch and hearing. This paper presents the prototype of a low cost smart glove to improve the mobility of the visually impaired people. The glove is equipped with rangefinders to explore the surroundings: it provides a vibro-tactile feedback on the position of the closest obstacles in range by means of vibration motors. The system is designed to operate with the white cane, enhancing the reliability of this traditional tool

A Novel Architecture for Cyber-Physical Security in Industrial Control Networks
No full textOver the last decades, the evolution of information and communication technology has joined the automation and control systems development, leading to Cyber-Physical Systems integration in industrial environments. Since complex threats targeting physical processes require advanced and interdisciplinary security approaches, classic cyber-security tools are ineffective in industrial scenarios. In this paper, we present a modular framework able to provide cyber-physical security for industrial control systems. Our Deep Detection Architecture (DDA) fills the gap between computer science and control theoretic approaches. Moreover, we present an innovative cyber-physical simulation methodology as a baseline for validation purposes
Monitoring system reaction in cyber-physical testbed under cyber-attacks
No full textIn this paper, we exploit the cyber-physical testbed developed within the EU Project FACIES to analyze how monitor systems, typically used in Industrial Control Systems, may be prone to fail when facing cyber-attacks. Specifically, through several experimental trials, we test the poor ability of a Fault Diagnosis module to correctly manage cyber-attacks, which generally turn to be considered physical faults, forcing operators to perform erroneous countermeasures. To conclude, we outline how the presence of a cyber Intrusion Detection System improves the effectiveness and the reliability of the protection schema. The experimental validation has been carried out on an emulated water distribution system
Network anomaly detection in critical infrastructure based on mininet network simulator
No full textIn this paper, a highly-configurable network anomaly detection system for Critical Infrastructure scenarios is presented. The Mininet virtual machine environment has been used in this framework to simulate an Industrial Control System network and to replicate both physical and cyber components. Finally, a cyber-attack has been implemented for showing both the effectiveness and capability of the proposed network security system
Detecting integrity attacks in IoT-based cyber physical systems: A case study on hydra testbed
No full textThe Internet of Things paradigm improves the classical information sharing scheme. However, it has increased the need for granting the security of the connected systems. In the industrial field, the problem becomes more complex due to the need of protecting a large attack surface while granting the availability of the system and the real time response to the presence of threats. In this contribution, we deal with the injection of tampered data into the communication channel to affect the physical system. The proposed approach relies on designing a secure control system by coding the output matrices according to a secret pattern. This pattern is created by using the Fibonacci p-sequences, numeric sequence depending on a key. The proposed method is validated on the Hydra testbed, emulating the industrial control network of a water distribution system
