SECURING CAN NETWORKS IN
COMMERCIAL VEHICLES
The Secure CAN transceivers enable meeting some of the UNECE R155 security mitigation requirements for CAN networks.
from different subassemblies, the suppliers need to be able to secure
each subassembly's network locally, and independently, so that when
they come together at the OEM, there aren't additional security vulnerabilities
introduced.
Affordable security is a must - Last but not the least is the commercial
aspect of implementing security measures. While there is an
increasing number of commercial vehicles hitting the road, driven by
demand from industries such as construction and e-commerce, the
numbers are still vastly lower than those of passenger cars. This
places significant pressure on the development costs of CVs. CV security
solutions, therefore, need to not only be easy to implement
but also affordable.
Secure CAN transceivers
These challenges highlight the need for an affordable and easy to
configure, integrate and validate solution. One possibility is Secure
CAN transceivers, which can serve to ensure authentication of communication
on a local network - i.e., for CAN data frames not transmitted
over a gateway. It does so by using a configurable transmission
pass-list, or list of user pre-configured CAN-IDs, built into the
transceiver itself. This ensures that the local host is only allowed to
send these legitimate CAN data frames.
A CAN-ID block-list ensures that no other node uses the CAN-IDs
that are legitimately owned by the aforementioned local host. The
J1939 protocol specifies unique source addresses (SA) for ECUs (to be
assigned by the network designer), which can be masked using the
secure CAN transceivers to enable securing the communication based

on a pass-list and block-list for CAN-IDs as determined
by the OEM to fulfill the network's security requirements.
To circumvent the Secure CAN spoofing protection,
a hacker could attempt to carry out a man-in-the-middle
attack to manipulate a legitimately initiated CAN
frame by taking control at the data field to insert
rogue data along with an appropriately altered CRC
value. In Error Active state, the CAN controller detects
and invalidates the manipulated frame. However, in
Error Passive state, the modifications are not signaled
