Embodiment Construction

[0037] The system according to the invention proposes as a main component a transformation module 1 which is developed and arranged to ensure the specification of an unambiguous description of cryptographic material using an abstract and executable formal language. The "transformation into the syntax of the cryptographic material generator 2, which will be described in greater detail and described later" can be achieved here basically in two different ways. One of the ways is as in figure 1 is shown in and relies on Translator 4. through the figure 1 and figure 2 In the user interface 3 not shown in , the specification SPEC is entered, precisely for the specific application n for which encrypted material is to be generated. Then, the specification SPEC n enters the translator 4 and is thereby converted into the source code QC for the corresponding application n. Then, source code QC n Installed on the cryptographic material server 5 as a program is a corresponding high-...

Abstract

The invention relates to a system for producing cryptographic material (CM), comprising a cryptomaterial server (5) and a developer module (11), wherein the cryptomaterial server (5) comprises at least one cryptomaterial generator (2) and a cryptomaterial distributor (10), wherein the cryptomaterial generator (2) is designed to generate cryptographic material (CM) on the basis of specifications (SPEC) which can be specified via the developer module (11). The system according to the invention is characterised in that the cryptomaterial server (5) has a receiving part of a specification interface (9) and the developer module (11) has a corresponding sending part of the specification interface (9) which can be connected directly or indirectly for the secure transmission of data; the developer module (11) has a user interface (3) or can be coupled directly or indirectly to such an interface, which is designed for an input of the specifications (SPEC) in abstract form, and a transformation module (1) being provided for the automatic transformation of the input specifications (SPEC) into a syntax of the cryptomaterial generator (2).

Description

technical field [0001] The invention relates to a system for generating cryptographic material of the type defined in detail in the preamble of claim 1 , having a cryptographic material server and a development module. The invention also relates to a method for generating encrypted material with such a system. Background technique [0002] The use of encrypted data is absolutely essential in many modern systems to achieve reliable and secure communication that cannot be tampered with by third parties. Modern vehicles in particular are characterized by increasing networking. Here, the vehicle is not only connected to publicly accessible systems such as the World Wide Web or the Internet, but also to dedicated systems provided by vehicle manufacturers and service providers, such as applications developed and operated by manufacturers specifically for their own vehicles or fleets, for example or server. Service providers can also cooperate with manufacturers to provide corre...
