Volkswagen Uses Infineon’s TPM to Protect Sensitive Data

January 25, 2019 Laura Dolan

Munich, Germany. Volkswagen has deployed Infineon Technologies’ OPTIGA Trusted Platform Module (TPM) 2.0 connected cars’ security solution, as its chip is designed to protect the vehicle’s outside communication.

The TPM specifically protects the vehicle’s external interfaces by verifying the identities of senders and recipients of digital data by encrypting and decrypting data.

The TPM stores cryptographic keys used for security functions, acting much like a safe. The initial keys were imported by Infineon in a specially certified security environment. The TPM is also protected against physical attacks, preventing someone from reading the chip or removing the chip from the vehicle. 

The OPTIGA TPM 2.0 is also designed to withstand the extended lifecycles of cars. Its firmware, including cryptographic mechanisms, can be revised remotely ensuring that its security technology is always updated.
