A Hardware Accelerator for the IEEE 802.1X-2010 Key Hierarchy in Automotive Applications
In recent years, the complexity of automotive networks
has increased, leading to broad security issues related
to human safety. Furthermore, car-to-car communication and
the interaction between cars and the external environment seem
to be the next step of the Internet of Things (IoT) paradigm.
To solve problems of network overload, the automotive world
is increasingly moving in the direction of using an Ethernet
backbone for in-vehicle communications. Therefore, the security
of Ethernet protocols has become a significant concern. The
IEEE 802.1AE MAC Security standard could be a suitable
solution for this purpose. It maintains the confidentiality and
integrity of data, but leaves the problem of authentication and
key management unresolved. The IEEE 802.1X-2010 standard
solves this issue, including solutions that allow the secure usage
of the IEEE 802.1AE MAC Security standard. In this work, an
efficient hardware accelerator for IEEE 802.1X-2010 is presented.
The system was synthesized both on a Stratix V FPGA and
on a 40nm standard-cell library. The former gives a usage of
3% of the Adaptive Logic Modules (ALMs) while the latter
shows an occupation of 55 kgates. On the FPGA, the maximum
throughput is 152 Mbps and 1.14 Gbps for the two sections of
the algorithm, respectively, while the standard-cell technology
provides a maximum throughput of 457 Mbps and 3.85 Gbps. This
solution suggests an interesting implementation when fast, lowarea,
and secure key-management solutions for Ethernet networks
are required
