The Advantages of TLS and Cryptography in Automotive Security

for Applications, Devices, IoT, and the Cloud

Increased complexity and safety in the Automotive Industry requires increased security. With the growing number of interconnected electronic parts, diagnostics, auto break engagement, etc, there are more attack vectors that need to be secured. wolfSSL is the perfect TLS and Cryptography Library to use because:

Does Your ECU Need SSL/TLS?

wolfSSL is an embedded TLS library providing secure communication for IoT, smart grid, connected home, routers, applications, games, phones, and more. wolfSSL provides embedded stack/OS support (e.g lwip, FreeRTOS, bare metal etc),and it works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.3 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. If your ECU is using OpenSSL consider migrating to wolfSSL for hardware encryption, ISOTP and CAN support.

The CMVP has issued FIPS 140-3 validated Certificate #4718 and FIPS 140-2 Certificates #3389 and #2425 for the wolfCrypt Module developed by wolfSSL Inc. wolfCrypt has been DO-178C DAL-A certified for avionics. For more information, see our FIPS FAQ.

Does Your ECU Need Secure Boot?

wolfBoot is a portable secure bootloader solution that offers firmware authentication and firmware update mechanisms. Due to its minimalistic design and tiny HAL API, wolfBoot is completely independent from any OS or bare-metal application.

wolfBoot can be easily ported and integrated in existing embedded software projects to provide a secure firmware update mechanism. Upon installing a verified update, wolfBoot creates a backup copy of the last firmware image known to work correctly. If the new version is not confirmed by the application, or if the image installed is somehow corrupted, the bootloader will restore the state of the system before the most recent update. Supports multiple binary formats including Intel HEX.
