Method and system for improving the data security during a communication process

Abstract

A system for improving the data security during a communication process, including at least one processor and a hardware security module. The communication data is authenticated prior to a transmission process, and the authenticity of the communication data is checked upon being received. The authentication is carried out by the processor, and the authentication check is carried out by the hardware security module, wherein the communication data is car-to-X messages. The processor and the hardware security module are linked via a common secret element such that at least the hardware security module cannot be coupled to another processor.

Dependencies are inferred from the claim text.
