Abstract: According to various embodiments, a control device is described including an application core including a processor, a memory and a direct memory access controller and a security module coupled to the application core via a computer bus. The direct memory access controller is configured to read data from the memory, generate a hash value for the data and provide the hash value to the security module via the computer bus. The security module is configured to process the hash value.
