Firmware / Software Update over the Air Proof of Concept

By 2020 industry experts expect more than 250 million connected vehicles on the road. The need to perform frequent remote software updates of car components increases with the level of automation – especially with autonomous cars. IOTA envisions becoming the underlying protocol for car makers and suppliers to ensure secure updates and transparent access to audit trails.

The Challanges Today

Centralized ownership of data makes it difficult to ensure that the data are not tampered with. This lack of transparency leads to limited trust between parties and extensive documentation processes. Multipartner ecosystems create an intransparent audit trail and proof of untampered data can’t be ensured easily.

The Project Goals

  • Documentatlon of over the air update (OTA) process steps on an immutable data storage medium and audit trail, where data integrity can be ensured.
  • Integration of IOTA technology into the existing legacy system to prove interoperability and production readiness.

Core Benefits for Volkswagen

  • Establish transparency and digital trust with customers, authorities and third parties.
  • Ability to provide an evidence to external parties.
  • Handle product recalls efficiently.
  • Ability to record high volume of (incremental) updates and different software versions
  • Tamper proof & transparent statistical recording

More Opportunities

  • On Demand Features: Request and configure car related features
  • V2V and V2I Communications: Exchange information, data and resources
  • Ecosystem: Use secure and immutable data to customize services like usaged based insurance
