The research presented focuses on cryptographic-agility for End-to-End Encryption systems (E2EE) that could be implemented for telemetry data encryption. The recent report 1 by Microsoft after a security incident, describes the consequences that lead to encryption key leakage from telemetry data of highly protected production system. Internet of Things (IoT) and mobile devices constantly produce telemetry data which contains sensitive information. The data partially belongs to vendor, but IoT consumer’s consent is needed to access such data for troubleshooting or forensic analysis. Goyal et al [2] proposed Attribute Based Encryption (ABE) as a solution for legitimately access the audit log contents by engineering team. © 2024 Copyright held by the owner/author(s).
