    • An error detection device for a command decoder is described, the command decoder reading out an associated sequence of control signal words from a command memory based on an input word, wherein the sequence of control signal words has at least one control signal word, having: a controller designed to provide the input word at a first time and the input word at a second time for reading out the command memory, wherein the second time is delayed with respect to the first time, to effect a readout of the sequence of control signal words at a first time and a readout of the sequence of control signal words at a second time; and a comparator designed to receive and compare the associated sequences of control signal words read out at the first and second times, and to output a signal indicating an error if the associated sequences of control signal words read out at the first and second times are different.
    • 描述了一种用于命令解码器的错误检测装置,命令解码器基于输入字从命令存储器中读出相关序列的控制信号字,其中控制信号字序列具有至少一个控制信号字,具有: 控制器,其被设计为在第一时间提供输入字,并且输入字在第二时间用于读出指令存储器,其中第二时间相对于第一次被延迟,以实现控制信号序列的读出 第一时间的字和读出控制信号字的序列; 以及比较器,用于接收和比较在第一次和第二次读出的控制信号字的相关序列,并且如果在第一次和第二次读出的相关序列的控制信号字不同,则输出指示错误的信号 。

    • An undesired change of encrypted data words of a stored encrypted dataset may be concluded from the fact that redundancy information is associated with the data words of a dataset prior to encryption, wherein the redundancy information is also encrypted and stored at least partially together with the encrypted data words of the encrypted dataset as an encrypted redundancy data word. The change of the stored encrypted data words may be concluded from the fact that the decrypted data words resulting from decrypting the encrypted data words are used to form a new redundancy data word which is encrypted into a new encrypted redundancy data word. A comparison of the new encrypted redundancy data word to the encrypted redundancy data word enables to examine whether the encrypted data was changed.
    • 存储的加密数据集的加密数据字的不期望的改变可以从冗余信息与加密之前的数据集的数据字相关联的事实得出,其中冗余信息也被加密并且与加密的数据字一起被部分地存储 加密数据集的数据字作为加密冗余数据字。 存储的加密数据字的改变可以从以下事实得出:从解密加密数据字得到的解密数据字用于形成新的冗余数据字,该冗余数据字被加密成新的加密冗余数据字。 新加密冗余数据字与加密冗余数据字的比较使得能够检查加密数据是否被改变。
