    摘要: A communication apparatus for communication according to a master-slave communication protocol is formed as a slave instance communicating with a master instance via a bus. The master instance is operative to switch the bus into a bus suspend state if no bus activity is present during a predetermined interval. In response to a bus suspend state, the slave instance makes a transition to a slave suspend state. The communication apparatus includes a monitor configured to monitor the bus activity and a transmitter configured to transmit a signal via the bus if the monitor does not recognize any bus activity during part of the predetermined interval and a transition of the slave instance to the slave suspend state is undesirable, wherein the signal is operative to prevent the master instance from switching the bus into the bus suspend state.

    摘要: A method for determining a physical address from a virtual address, wherein a mapping regulation between the virtual address and the physical address is implemented as hierarchical tree structure with compressed nodes. First, a compression indicator included in the mapping regulation is read, and a portion of the virtual address associated with the considered node level is read. Using the compression indicator and the portion of the virtual address, an entry in the node list of the considered node is determined. The determined entry is read, whereupon the physical address can be determined directly, if the considered node level has been the hierarchically lowest node level. If higher node levels to be processed are present, the previous steps in determining the physical address for compressed nodes of lower hierarchy level are repeated until the hierarchically lowest node level is reached.

    摘要: A shift device for shifting a first place of a data word, which consists of a plurality of places, to a second place so as to obtain a shifted data word, wherein the first place is encrypted using a first encryption parameter and wherein the second place is encrypted using a second encryption parameter, includes a unit for shifting the first place of the data word to the second place of the data word, a unit for re-encrypting the first place from an encryption using the first encryption parameter into an encryption using the second encryption pa- rameter, and a control for controlling the unit for shifting and the unit for re-encryption so that the first place is first shifted to the second place and is then re-encrypted, or that the first place is first re-encrypted and is then shifted to the second place. This ensures that data encrypted either with the first encryption parameter or with the second encryption parameter are always shifted, thus making it harder for attackers to eavesdrop on clear text data.

The device includes a non-volatile memory element in each of the two semiconductor chips, wherein an encryption initial value for an encryption rule is stored in the memory element of the first semiconductor chip and a decryption initial value associated to the encryption initial value for a decryption rule associated to the encryption rule is stored in the memory element of the second semiconductor chip. Additionally, the first semiconductor chip has a first data transmission interface formed to generate an encryption data stream from an input data stream using the encryption initial value according to the encryption rule. Also, the second semiconductor chip has a second data transmission interface formed to receive the encryption data stream and to generate a decryption data stream from the encryption data stream using the decryption initial value according to the decryption rule and to compare the decryption data stream generated to an expected data stream, wherein the second data transmission interface is also formed to perform a defensive measure against transmitting data from the second data transmission interface to the first data transmission interface when the decryption data stream does not correspond to the expected data stream.
