Now, for the first time, with the Azure Sphere OS 20.07 release, Microsoft has licensed and exposed a subset of wolfSSL for use on Azure Sphere devices, allowing software developers to create client TLS connections directly using the Azure Sphere SDK. Software developers no longer need to package their own TLS library for this purpose. Using the wolfSSL support in Azure Sphere can save device memory space and programming effort, freeing developers to build new IoT solutions.
Microsoft Azure Sphere and wolfSSL have been long-time partners, striving for the very best in security. The Azure Sphere OS has long used wolfSSL for TLS connections to Microsoft Azure services. Azure Sphere also uses wolfSSL technology to enable secure interactions from developer apps to customer-owned services.
Partnerships with leaders like wolfSSL play an important role in Azure Sphere’s mission to empower every organization to connect, create, and deploy highly secured IoT devices. The unique Azure Sphere approach to security is based on years of vulnerability research, summarized in the seminal paper “Seven Properties of Highly Secure Devices.” These seven properties are the minimum requirement for any connected device to be considered highly secured. Azure Sphere implements all seven properties, providing a robust foundation for IoT devices.
Azure Sphere can be used with any customer cloud service, not just Microsoft’s own Azure. By providing a highly secured ecosystem, Microsoft and wolfSSL make security features more accessible and easier to use and can extend unmatched security to the frontiers in IoT where security has historically been sparse.
For information on how to use the wolfSSL API on Azure Sphere, please see Use wolfSSL for TLS connections in the online documentation. We plan to publish a related sample application, available at a later date. Check back here—we will update this post with the link to the sample once it is available.
