Abstract

A method for implementing an encrypted client-server communication, wherein the server includes an entry point, service systems behind the entry point, and a secure system. The method includes incorporating common cryptographic material into the client and into the secure system, deriving key material from the common cryptographic material in the client for an encrypted communication between the client and a service system, deriving key material from the common cryptographic material in the secure system for an encrypted communication between the client and a service system, and transferring the key material into the service system or retaining the key material in the secure system.
