| Crypto Driver Object | A Crypto Driver implements one or more Crypto Driver Objects. The Crypto Driver Object can offer different crypto primitives in hardware or software. The Crypto Driver Objects of one Crypto Driver are independent of each other. There is only one workspace for each Crypto Driver Object (i.e. only one crypto primitive can be performed at the same time). |
| Crypto Primitive | A crypto primitive is an instance of a configured cryptographic algorithm realized in a Crypto Driver Object. |
| Job | A job is a configured crypto primitive together with a referenced key. |
| Key | A key can be referenced by a job or by a key management function in the CSM. In the Crypto Driver, the key refers a specific key type. |
| Key Element K | ey elements are used to store data. This data can be, e.g., key material or the IV needed for AES encryption. It can also be used to configure the behavior of the key management functions. |
| Key Type | A key type consists of references to key elements. The key types are typically pre-configured by the vendor of the Crypto Driver. |
| Processing | Indicates the kind of job processing. |
| Asynchronous | The job is not processed immediately when calling a corresponding function. Usually, the caller is informed via a callback function when the job has been finished. |
| Synchronous | The job is processed immediately when calling a corresponding function. When the function returns, a result will be available. |
