摘要： The aim of the embodiments is to provide a method for the secure processing of data, in which security is increased in relation to side channel attacks. To achieve this, operation codes for commanding co-processors are determined, for example for the bit-dependent transposition of register contents. The solution exploits the fact that as a result of the technical configuration for the co-processor, a shift of register contents, for example from register A to register B cannot be differentiated from the exterior from a shift from register A to register C.

摘要： An IT system includes at least one first processing unit and one second processing unit. The first and second processing units jointly execute an application program and are each associated with an installation routine designed to control updating of a first or second program part of the application program. A first actual state is associated with the first processing unit and a second actual state is associated with the second processing unit. After system reboot, or as soon as the first and second program part have been successfully stored, or an error is detected when storing the first and/or second program part, predefined processing steps are respectively carried out in a predefined order by the first processing unit aid the second processing unit depending on the actual state of the first processing unit and the actual state of the second processing unit.
摘要翻译： IT系统包括至少一个第一处理单元和一个第二处理单元。第一处理单元和第二处理单元共同执行应用程序，并且各自与安装例程相关联，该安装程序旨在控制应用程序的第一或第二程序部分的更新。第一实际状态与第一处理单元相关联，第二实际状态与第二处理单元相关联。在系统重新启动之后，或者一旦第一和第二程序部分已被成功存储，或者当存储第一和/或第二程序部分时检测到错误，则通过第一处理以预定义的顺序分别执行预定义的处理步骤单元根据第一处理单元的实际状态和第二处理单元的实际状态来辅助第二处理单元。
