Crypto Driver Object A Crypto Driver Object is an instance of a crypto module (hardware or software), which is able to perform one or more different crypto operations.
User A user is a configured object with an ID and configured jobs.
Channel A channel is the path from a Crypto Service Manager queue via the Crypto Interface to a specific Crypto Driver Object.
Job A job is an instance of a user’s configured cryptographic primitive.
Primitive A primitive is an instance of a configured cryptographic algorithm realized in a Crypto Driver Object. Among others it refers to a functionality provided by the CSM to the application, the concrete underlining 'algorithmfamily' (e.g. AES, MD5, RSA, etc.), and a 'algorithmmode' (e.g. ECB, CBC, etc).
Operation An operation of a crypto primitive declares what part of the crypto primitive shall be performed. There are three different operations: It is also possible to perform more than one operation at once by concatenating the corresponding bits of the operation_mode argument.
START Operation indicates a new request of a crypto primitive, and it shall cancel all previous requests.
UPDATE Operation indicates, that the crypto primitive expect input data.
FINISH Operation indicates, that after this part all data are fed completely and the crypto primitive can finalize the calculations.
Priority The priority of a user defines the importance of it. The higher the priority (as well in value), the more immediate the user's job will be executed. The priority of a cryptographic job is part of the user’s configuration.
Service A service shall be understand as defined in the TR_Glossary document: A service is a type of operation that has a published specification of interface and behavior, involving a contract between the provider of the capability and the potential clients.
