Proposed Methods t o Rollback A Failed Update of IoT Devices

Abstract

The increasing number of IoT devices leads to the demand for updating them securely, and stably. Without updating there is a high risk of being attack by hackers or malfunction due to outdated packages. To the date of this article, a lot of IoT updating methods were introduced. Among them are updating using VM containers, using packages, or using blockchain. However, some methods take time to recover a failed update while some cases require the minimum downtime of the IoT devices, or even some devices cannot communicate to the control server or cannot perform the rollback themselves after the update failure. In this article, our contribution is implementing different methods to reduce the rollback down time issue including using primary - secondary selection, using git revert, and using blockchain-based revert.
