Toyota Infotechnology Center and Fujitsu are cooperating to improve the security of vehicles.
The two companies announced that they are jointly developing a technology to protect vehicles from being hacked. Toyota Infotechnology Center was invested in by Toyota Motor Corp, Denso Corp, etc.
The technology being developed by Toyota Infotechnology Center and Fujitsu improves security by, for example, encrypting information to be exchanged among the electronic control units (ECUs) of a vehicle and between an ECU and data center. The technology generates cipher keys with a special chip in an ECU. Also, there are a function to authenticate ECUs and a technology to remotely and safely update software.
“To ensure the safety of users and reassure them, we want to protect ECUs from malicious attacks and intrusions,” Toyota Infotechnology Center said.
The new technology under development will be a future design guideline for auto parts manufacturers that deal with ECUs, etc, he said.
The special chip is a hardware security module (HSM) with specifications called “TPM (Trusted Platform Module).” The TPM is added to an ECU in the aim of protecting a vehicle from being hacked by malicious third parties.
Toyota Infotechnology Center and Fujitsu will deliver a lecture on the technology and demonstrate it at the SAE 2015 World Congress & Exhibition, an academic conference on automotive technologies, which will take place from April 21 to 23, 2015, in Detroit, the US.
The specifications of the TPM is designed by TCG (Trusted Computing Group), an industry standards body that Intel, Hewlett-Packard, IBM, Microsoft, Fujitsu, etc established in 2003 in the aim of improving information security. It made the automotive version of the TPM available to the public in March 2015. Toyota joined TCG in 2012.
