Secure OTA Update Workshop by Tonex
Modern devices never stand still, and neither should their software. This workshop dives into end-to-end strategies for designing, deploying, and governing secure over-the-air firmware and software updates across embedded, IoT, automotive, and edge systems. You will learn how to harden update pipelines, validate integrity, and sustain reliability at scale while reducing downtime and field risk. Strong authentication, encryption, and attestation are emphasized to block tampering and rollback attacks. We also examine secure key management and supply chain trust so adversaries cannot insert malicious images. The result is resilient OTA that strengthens cybersecurity posture and protects customers and brand.
