Specification of Crypto Driver, AUTOSAR 807, R22-11, CP, 20230421

Last updated at 2023-07-15Posted at 2023-07-15

AUTOSARは自動車用OSの業界団体規格です。　
業務で利用する場合には、会員になることを条件にしています。

2002年から20年経ち、当初の狙いの段階に近づいてきました。

MATLABでモデルさえ記述すれば、あとは自動生成だけでソフトが完成するところまで、あと一歩です。
Ethernet, UNIXが生まれて20年で大衆化したのと同じように考えると分かりやすいでしょう。　

AUTOSARの上で動く、クラウド対応のミドルウェアが出て、開発も運用もクラウドになれば、一気にAUTOSARは大衆化するでしょう。

用語(terms)

Term	Description
CDD	Complex Device Driver
CSM	Crypto Service Manager
CRYIF	Crypto Interface
CRYPTO	Crypto Driver
DET	Default Error Tracer
HSM	Hardware Security Module
HW	Hardware
SHE	Security Hardware Extension
SW	Software
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) The only exception of independency between Crypto Driver Object is the usage of a default Random Number Generator (see [SWS_Crypto_00225]).
Key	A Key can be referenced by a job in the Csm. In the Crypto Driver, the key references a specific key type.
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.
Key Element	Key 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 behaviour of the key management functions.
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 a configured 'CsmJob'. Among others, it refers to a key, a cryptographic primitive and a reference channel.
Crypto Primitive	'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, ...), and a 'algorithmmode' (e.g. ECB, CBC, ...).
Operation	An operation of a crypto primitive declares what part of the crypto primitive shall be performed. There are three different operation modes:It is also possible to perform more than one operation at once by concatenating the corresponding bits of the operation mode argument.
START	Operation mode indicates a new request of a crypto primitive, and it shall cancel all previous requests of the same job and primitive.
UPDATE	Operation mode indicates, that the crypto primitive expects input data.
FINISH	Operation mode indicates, that after this part all data are fed completely and the crypto primitive can finalize the calculations.
Priority	The priority of a job defines the importance of it. The higher the priority (as well in value), the more immediate the job will be executed. The priority of a cryptographic job is part of the configuration.
Service	A 'Service' shall be understood 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.
