Title: METHOD AND ARRANGEMENT FOR SECURE ELECTRONIC DATA COMMUNICATION
Abstract:
The invention relates to an arrangement (10) for secure electronic data communication according to the publish/subscribe model between information-processing units (21; 31) of the arrangement. The data communication is secured on the basis of an asymmetric encryption method. Each of the information-processing units (21; 31) is associated with a hardware-type secured zone (20; 30) in which the respective information-processing unit (21; 31) is arranged. A zone key pair (120; 130) consisting of a public zone key (122; 132) and a secret zone key (124; 134) is associated with each of the zones (20; 30). Each of the zones (20; 30) comprises an encryption unit (25; 35) embodied as a hardware module, which is designed to store the secret zone key (124; 134) in a secure manner and to perform cryptographic operations by means of the secret zone key (124; 134).
