As automotive software continues to grow in complexity, functional safety has become just as important as cybersecurity. To help customers build safety-critical systems, wolfSSL now offers ISO 26262 documentation designed to simplify the integration of wolfSSL into products pursuing Automotive Safety Integrity Level (ASIL) certification.
This documentation provides developers with the supporting materials needed to incorporate wolfSSL into ISO 26262 safety cases, reducing the effort required to evaluate and qualify the cryptographic component as part of a larger automotive system.
Understanding ISO 26262 and ASIL
ISO 26262 is the international standard for functional safety in electrical and electronic systems used in road vehicles. It defines a rigorous development lifecycle and a risk-based approach for ensuring that automotive software and hardware operate safely, even in the presence of faults.
The standard defines four Automotive Safety Integrity Levels (ASIL A through ASIL D), with ASIL D representing the most stringent level of safety assurance for systems where failures could have the most severe consequences.
For software components such as cryptographic libraries, achieving compliance requires comprehensive development processes, traceability, verification activities, and supporting safety documentation.
How wolfSSL’s ISO 26262 Documentation Helps
wolfSSL’s ISO 26262 documentation helps automotive developers accelerate their functional safety efforts by providing:
- Documentation that supports integration into ISO 26262 safety cases.
- Development and verification artifacts that reduce the amount of work customers must perform themselves.
- Increased confidence that the cryptographic foundation of their application has been developed using processes aligned with functional safety objectives.
By reducing the documentation burden, development teams can spend more time focusing on their application while maintaining confidence in the security and reliability of the underlying cryptographic library.
Our Certification Journey
The availability of ISO 26262 documentation represents an important milestone in wolfSSL’s long-term functional safety strategy. Our goal is not simply to provide supporting documentation, but to deliver independently certified software components that automotive manufacturers and Tier 1 suppliers can confidently integrate into safety-critical systems.
To that end, we are actively pursuing ISO 26262 certification in partnership with TÜV SÜD, one of the world’s leading independent certification organizations for functional safety. Working alongside TÜV SÜD ensures that our development processes, documentation, verification activities, and safety lifecycle are independently assessed against the rigorous expectations of the automotive industry.
This certification effort includes significant investments across multiple areas, including:
- Continued enhancement of our functional safety development lifecycle.
- Expanded requirements traceability across the project.
- Comprehensive verification and validation activities.
- Detailed safety analyses and supporting documentation.
- Continuous process improvements aligned with ISO 26262 best practices.
- Independent assessments and audits conducted throughout the certification process.
Our engineering and quality teams are working diligently toward achieving ASIL D certification for both wolfSSL and wolfCrypt, with a target completion in Q1 2027. Achieving this milestone will further demonstrate our commitment to delivering cryptographic software that satisfies the demanding requirements of both cybersecurity and functional safety in modern automotive systems.
Reaching ASIL D certification is only the beginning. Once certification has been achieved for wolfSSL and wolfCrypt, we will extend our ISO 26262 certification program to additional products developed specifically for automotive environments, including wolfHSM, wolfBoot, and wolfIP. Our vision is to build a comprehensive portfolio of functionally safe embedded software that enables customers to deploy trusted security, secure boot, hardware security module functionality, networking, and cryptography from a single, proven ecosystem.
Automotive Applications
wolfSSL’s small footprint, high performance, and portability already make it an excellent choice for embedded systems, including:
- Vehicle-to-Everything (V2X) communications
- Advanced Driver Assistance Systems (ADAS)
- Electronic Control Units (ECUs)
- Battery Management Systems (BMS)
- Automotive gateways
- Secure over-the-air (OTA) software updates
- In-vehicle infotainment systems
As software-defined vehicles continue to evolve, the demand for solutions that meet both cybersecurity and functional safety requirements will only increase. wolfSSL is committed to helping customers address these challenges by investing in the processes, documentation, and independent certification needed for next-generation automotive platforms.
The release of our ISO 26262 documentation is an important milestone on that journey. Together with our ongoing certification efforts in partnership with TÜV SÜD and our roadmap toward ASIL D certification in Q1 2027, it represents another step toward delivering a complete portfolio of safety-ready embedded security solutions for the automotive industry.
Taking the Next Step
Whether you’re retrofitting cryptography into an existing system or building a new solution from the ground up, wolfSSL’s new ISO 26262 documentation reduces the friction for compliance while delivering the performance and security you trust.
