Luna HSM Encryption for Mitsubishi Electric Sanda Works - Case Study

Cars continue to evolve. 

Electric vehicles, automatic driving (AD), and advanced driver-assistance systems (ADAS) are now common in society. Companies are also producing software-defined vehicles (SDVs) that conduct over-the-air (OTA) bidirectional communication between the vehicle and an external source for maintenance and to improve the functionality of the vehicle. 

However, vehicles controlled by software that can be updated via data communications are subject to the risks of external hacking or information leakage; they require a new level of sophisticated security. 

Sanda Works of Mitsubishi Electric in Hyogo Prefecture has made significant innovations by deploying Thales Luna Hardware Security Modules (HSMs) into the process for writing software into microcomputers called Electric Control Units (ECUs), which are used for electronically controlling ADAS products. Sanda Works successfully created and implemented a system for robust protection of the entire lifecycle from the development of ECU software to production.
