In the course of digital transformation, many applications rely on digital signatures in order to protect the authenticity and integrity of information. Due to legal or organisational requirements, such applications need a certain level of protection of their signature keys, i.e. private signature keys must be protected from unauthorized usage and disclosure  via a suitable secure component.  Such a level  of  protection can be achieved by the usage of a Secure Element (SE).

The BSI TR-03151 specifies the Secure Element API (SE API). The SE API is  a digital interface that wraps functionality of a Secure Element and allows access to security functionalities by an application in a standardized way regardless of the specific type of Secure Element in use.
