Security Context Topics

This page covers the using BSL from the perspective of a developer of a new Security Context (SC) for the BSL.

Security Context Callback API

The BSL dynamic backend declares a set of functions which are delegated to each SC instance and are registered in the backend using the BSL_SecCtxDesc_t. These functions include some bookkeeping of the SC instance itself (associated user data and deinit function).

The operational focus of the SC callbacks are functions used by the BSL to:

• Validate the options for a specific security operation associated with the SC (as BSL_SecCtxDesc_s::validate).
• Execute a specific security operation associated with the SC (as BSL_SecCtxDesc_s::execute).
