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:

  • wolfSSL products are used by all the top 10 automotive OEM’s
  • 15+ years developing embedded security products
  • Major customers in Japan, Germany, USA and France
  • Of our 2,000 customers, ~10% automotive
  • 2 of the world’s biggest Auto vendors have standardized on us
  • wolfSSL provides static only memory support, hardware acceleration, minimal RAM usage relative to competitors, and nolibc
  • Multiple language interfaces including Perl, Python, PHP and Java for securely connecting ECU for testing and diagnostic functionality
  • Do you need to secure your DOIP? We can help with wolfSSL 
  • With thread safety wolfSSL is ready and compatible with multicore environments
  • Supports AUTOSAR

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 140-2 Certificates #3389 and #2425 for the wolfCrypt Module developed by wolfSSL Inc.  wolfSSL is on track to be one of the first crypto modules to be FIPS 140-3 validated. 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.
