LigSecOTA: Lightweight Over-the-Air (OTA) Software Updates With Integrated Security
- Published
- Record updated
Summary
The paper proposes LigSecOTA, a lightweight over-the-air software update scheme for automotive ECUs. It replaces certificates tied to physical identifiers such as the VIN with a one-machine-one-certificate digital identity system based on bit time information. The authors formally verify its security properties with ProVerif and report lower computation and communication overhead than state-of-the-art secure OTA updates on an NXP LS1028A platform.
