Transportation IoT
Security Solutions

Protect passengers, fortify cargo, and prevent manipulation of data by using PKI-based security solutions for transportation.


Why Transportation IoT Needs Security

Supplying smart planes, trains, and cars with the right security protocols is essential, especially after notable attacks. Risk to passengers increases as more unsecured vehicles come online.

How to Secure Transportation IoT

Customizable and deployed within milliseconds, PKI digital certificates are the perfect security solution for transportation IoT, providing authentication, encryption, and system integrity.

PKI Isn’t Just for Web Security

Despite common misconceptions, PKI is a perfect match for the exploding IoT sector, providing trust and control.

An ideal security solution for connected cars, trains, and planes, PKI can be incorporated during product design, build, deployment, or ongoing maintenance.


Digital certificates can size up or down to accommodate any type of device


PKI easily scales so you can manage high volumes of certificates effectively


IoT certificates are cost-effective and priced for high-volume orders

PKI for Connected Cars

PKI certificates keep connected cars safe by securing message
transmission—critical for protecting every person on the road.

Certificates encrypt and sign messages being sent to and from systems, maintaining integrity throughout the lifecycle and preventing interception or manipulation of data for vehicle-to-vehicle (V2V) or vehicle-to-everything (V2X) communications. We can help you tackle any connected car security challenge.

  • Design secure PKI architecture
  • Secure over-the-air (OTA) updates
  • Prevent malware
  • Encrypt messages and sensitive data
  • Mutual authentication of component parts (ECUs)
  • Secure vehicle gateway
  • Secure the vehicle’s CAN bus

Stay Ahead of the Curve

We are active in industry groups and follow efforts to secure connected automobiles. Our team can help you navigate initiatives such as Crash Avoidance Metrics Partnership (CAMP), Uptane (OTA Updates), and other ongoing industry activities.
