Finally, a scalable, cloud-based platform that can keep pace with the growing
number of access points in Transportation IoT.


Traffic can cause problems. Especially when it’s not encrypted.

In 2014, two hackers remotely accessed an SUV while it was cruising down the highway,

giving them control over the infotainment system, steering, brakes and more. The auto industry has since been designing new mechanisms to counter these attacks. But what if hackers bypassed these mechanisms entirely by finding a vulnerability within the car’s core system?

Infotainment System

Another group of researchers did just that, and it turned out to be a flaw in the CAN protocol used in most vehicles on the road today, allowing them to disable the brakes, airbags, locks and more. How do we fix these types of vulnerabilities?

Experts have suggested adding an encryption layer to the CAN bus to protect traffic coming
and going.

From Zero to Encrypted in Milliseconds

Customizable and deployed within milliseconds using RESTful APIs, DigiCert IoT certificates allow you to authenticate the vehicle’s CAN bus, encrypt gateway communications, provide secure over-the-air (OTA) updates and much more.

Certificates for car components validate identities to make sure only authorized users, messages or other types of servers have access to the device.
Certificates create an encrypted link and allow V2V and V2X communications to be transmitted privately.
Certificates ensure that any data transferred to and from the cloud, gateway or vehicle components, as well as the software in vehicles, are not altered.
