“…Manipulate power supply (CWE-1206): Besides disconnecting the power supply of the node, the attacker may manipulate the voltage (CWE-1247) to make the system unstable or provoke a higher error rate in computation (assuming improper voltage regulation on an embedded device) [ 45 ]. Furthermore, an attacker might want to perform side channel attacks via power-analysis in order to get access to system-relevant data such as private keys.…”

Today, visual sensor networks (VSNs) are pervasively used in smart environments such as intelligent homes, industrial automation or surveillance. A major concern in the use of sensor networks in general is their reliability in the presence of security threats and cyberattacks. Compared to traditional networks, sensor networks typically face numerous additional vulnerabilities due to the dynamic and distributed network topology, the resource constrained nodes, the potentially large network scale and the lack of global network knowledge. These vulnerabilities allow attackers to launch more severe and complicated attacks. Since the state-of-the-art is lacking studies on vulnerabilities in VSNs, a thorough investigation of attacks that can be launched against VSNs is required. This paper presents a general threat model for the attack surfaces of visual sensor network applications and their components. The outlined threats are classified by the STRIDE taxonomy and their weaknesses are classified using CWE, a common taxonomy for security weaknesses.

“…Voltage glitch attack (VGA) is a fault injection technique that exploits deliberately abrupt variation of the voltage level at the power supply of a CC [19,11,10,16,17]. Voltage glitches can lead to misinterpreting instructions of (crypto-) processor, failure to erase or overwrite data or retaining data from memory when not instructed [21,22,20].…”

The impeccable design of sensitive and cryptographic circuits (CC) against fault injection attacks is essential for modern data storage, communication, and computation systems that are susceptible to fault injection attacks. The robustness of a CC against voltage glitch attacks increases with an on-chip voltage regulator that considers the impact of topology and component selection on the fault injection robustness. With an emphasis on increasing the number of phases in a multiphase voltage regulator and component selection, an on-chip voltage regulator with multiphase configuration and an optimal operating point is proposed as a lightweight countermeasure to minimize injected glitches. Furthermore, an infective countermeasure is added to the on-chip multiphase voltage regulator that contaminates the computation of the cryptographic algorithm when a voltage glitch reaches to the CC. By increasing the number of phases from 1 to 16, the confrontation with fault attacks increases by 52.45%, which is equal to 91.82% if the number of phases increases to 32. Using the infective countermeasure for fault resiliency, the security-enhanced CC provides a robust and resilient solution against fault attacks that improve the security and availability of the device.
