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： By arranging a redundancy means and a control means upstream from an encryption means which encrypts and decrypts the data to be stored in an external memory, the integrity of data may be ensured when the generation of redundancy information is realized by the redundancy means, and when the generation of a syndrome bit vector indicating any alteration of the data is implemented by the control means. What is preferred is a control matrix constructed from idempotent, thinly populated, circulant square sub-matrices only. By arranging redundancy and control means upstream from the encryption/decryption means, what is achieved is that both errors in the encrypted data and errors of the non-encrypted data may be proven, provided that they have occurred in the data path between the redundancy/control means and the encryption/decryption means.

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.

Each operand is represented by two auxiliary operands, which, when linearly combined together result in the respective operand. The first and second logic gates are designed such that an average energy consumption of the first or second logic gate is substantially equal to a plurality of combinations of auxiliary operands at the beginning of a first operation cycle and auxiliary operands at the beginning of a second operating cycle, the average energy being derivable from a plurality of different orders of occurrences of the first to fourth auxiliary operands.

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.
