Embedded TLS and Cryptography Library

for Applications, Devices, IoT, and the Cloud

Increased complexity in the automotive industry requires increased security. With the number of increasingly interconnected ECU’s, there are more attack vectors in automotive than ever. wolfSSL is the perfect Embedded TLS and Cryptography Library for OEM’s and Tier 1’s to use because:

  • 15+ years experience in automotive
  • Major customers worldwide
  • Support for Autosar and all RTOS’s used in ECU design, even supporting bare metal
  • Support for the complex silicon used in automotive, including HSM’s like Aurix
  • wolfSSL products are used by all top 10 automotive OEM’s
  • 2 of the world’s biggest Auto vendors have standardized on us for security critical ECU designs

Does Your ECU Need SSL/TLS?

The wolfSSL embedded TLS library is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. wolfSSL supports industry standards up to the current TLS 1.3 and DTLS 1.3, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, is backed by the robust wolfCrypt cryptography library, and much more.

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.
