Feasible analysis on Hardware Security Module with digital voice assistants device

The advancement of the internet of things technology in the recent years is moving forward drastically due to the recent global pandemic started on the year 2020. Consumer product such as Digital Voice Assistant Device (DVAD) has become popular and is highly in demand. A security vulnerability is one of the major problems related to the IoT devices technology. One of the problem is the user data integrity issue, where DVAD users have no awareness of how their data is being used in the DVAD and if their DVAD are being tampered. With this in mind, the objective of this study is to investigate the feasibility and effect of hardware security module (HSM) onto a DVAD. A layer of security hardware is proposed, and the analysis focuses on the encryption ability, energy, and resource consumption are investigated. The findings revealed the HSM stack upon the DVAD is highly feasible and secure. The contribution of this study will add value to the existing literature on security for IoT technology. Besides, it is important for hardware-based security to consider the effect of feasibility which helps to improve the performance of such devices.
