V2X hardware add-on solution

SECTON is a V2X hardware add-on that is secure, cost-optimized, mass-market ready, architected for autonomous vehicles, flexible and can smoothly fit all customer architectures. It offers simple integration with any external host CPU. SECTON completely handles V2X security computation, thus making it cost-effective and hassle free, allowing application developers to focus on application reliability rather than vulnerability to Cybersecurity attacks.

SECTON is an automotive qualified chipset that integrates an enhanced-range mobility-optimized IEEE802.11p modem, an ultra-low-latency V2X Hardware Security Module (eHSM) and cryptoagile hardware verification engines. SECTON also supports IEEE 802.11a/b/g/n/ac to enable high-bandwidth external DSRC vehicle Wi-Fi for supplementary value-added services, like data synchronization with home and high-speed downloads. In addition, it has worldwide compliance, supporting US, EU and Japan standards.

  • Dual channel/diversity IEEE 802.11p mobility optimized modem
  • IEEE 802.11a/b/g/n/ac operation at 2.4GHz / 5GHz, up to 433 Mbps
  • Concurrent 802.11p/WLAN connectivity
  • Line-rate ECDSA and V2X-embedded HSM (Hardware Security Module)
  • AEC Q-100 grade 2 (-40°C to +105°C ambient operation)
  • Minimal thermal constraints due to high-temperature manufacturing process
  • USB 2.0 device interface
  • Provided with host drivers for Linux, QNX
