Abstract: This invention relates to a method of encrypting data packets of a data stream and decrypting plurally encrypted data of a data stream that provides an increased level of data security and can be automated using a signal sequence (a computer program product) or a data processing device. A data packet to be encrypted or a data packet to be decrypted is automatically encrypted or decrypted sequentially in at least two subsequent processing steps using different coding algorithms and different assigned coding keys. For encryption, a number, type, and sequence of different coding algorithms is first determined (S10) that is to be used in the subsequent encryption operations and respective different coding keys are assigned to the coding algorithms (S12, S13). Then the data packet to be encrypted is encrypted sequentially in at least two subsequent encryption operations (S16, S17) to obtain a plurally encrypted data packet.

Abstract: By forming a stressed semiconductor material in a gate electrode, a biaxial tensile strain may be induced in the channel region, thereby significantly increasing the charge carrier mobility. This concept may be advantageously combined with additional strain-inducing sources, such as embedded strained semiconductor materials in the drain and source regions, thereby providing the potential for enhancing transistor performance without contributing to process complexity.

Abstract: This invention relates to a network component (11-16) for a communication network (1) in which multiple communication interfaces (31-37) are connected for mutual data exchange via a transmission network (20) and in which said network component (11-16) can be placed between at least one assigned communication interface (31-37) and the transmission network (20). The network component (11-16) according to the invention comprises a first memory facility (41) for storing at least one preset coding key (K1, K2, K3), a decrypter (51) for decrypting the encrypted data received via the transmission network (20) using the stored at least one coding key (K1, K2, K3) as well as a data selector (52) for the selective transfer of data between the transmission network (20) and the at least one assigned communication interface (31-37).

Abstract: A work piece according to the invention has caulking tabs that are connected to each other by means of a bridge piece. As a result, the caulking tabs are lengthened, thus permitting better control of the caulking process because the caulking tabs overlap a component better.

Abstract: A work piece according to the prior art has caulking tabs with which it is difficult to control a caulking process due to tolerances.
