Claim:
1. A method for improving the functional safety and increasing the availability of an electronic closed-loop control system, for a motor vehicle control system, comprising: executing, by a processor, at least one basic software component, executing, by the processor, at least one runtime environment, and executing, by the processor, at least two levels of application software including: executing, by the processor, a first software component that manages encrypted data communicated from at least one peripheral hardware component in the vehicle over at least one communication channel to the processor, wherein the at least one peripheral hardware component executes at least one of data encryption and data signature to produce the encrypted data communicated from the at least one peripheral hardware component over the at least one communication channel to the first software component executed by the processor, and wherein the first software component manages the encrypted data communicated from the at least one peripheral hardware component by analyzing integrity, including plausibility, correctness and currentness of the encrypted data, wherein the first software component generates an error code which is processed by the at least one of the first and the second software level, when the integrity of at least one of the encrypted and the signed data is not existent, and wherein at least one of the unencrypted and the unsigned information data are not provided for the application software, or are provided together with the error code, or the unencrypted information data are assigned an implausible value.
