Drive safer, drive smarter.
Developed in Australia, our CANFlex system is hardened to increase functionality and security to your vehcile, keeping your journeys safe and reliable forever.
In the current iteration of CANflex, the window sizes of a frame are the same size as a maximum sized CAN bus frame. While this still allows for a performance increase, it is in efficient if there are multiple packets being served or the packet size is smaller than the allocated window for transmission. Therefore, there is the opportunity to further improve the performance and throughput of CANflex through optimisation.
The channel efficiency can also be improved through higher resolution clock syncing. Current synchronisation resolution allows for 90% data transfer and 10% slip however through successful implementation of NTP sync, it should be possible to reduce slip window to 1%, improving channel efficiency by as much as 10%.
When a CAN network is protected by the CANflex tunnelling protocol, it becomes not only more secure but more robust to any form of attack. The traditional MOTS and MITM attacks both become MOTS as they are “re-intercepted” by a trusted part of the network (figure below) and blocked when exiting the gateway.
The significance of this is that it improves transmission speed, reduces the effectiveness of DOS attacks, and allows for packet control that does not exist in CAN. What would previously be a successful attack, now at best can result in packet collisions with an equivalent MOTS attack.
We have seen first hand the dangers of insecure dashboard systems in automobiles. Its time this changes. Our state-of-the-art CANFLEX system ensures the best security practices to keep your vehicles’ dashboard from malfunctioning or attacked by potential hackers. Our secure CANflex network does just that.
