SHIFTING DEVICE AND SHIFTING METHOD

摘要

Disclosed is a shifting device for shifting the first place of a data word consisting of a plurality of places to a second place so as to obtain a shifted data word. The first place is coded by means of a first coding parameter while the second place is coded by means of a second coding parameter. The inventive shifting device comprises a device (10) for shifting the first place of the data word to a second place of the data word, a device (12) for recoding the first place, which has been coded by means of the first coding parameter, by means of the second coding parameter, and a control (14) controlling the coding device (10) and the recoding device (12) in such a way that the first place is first shifted to the second place and then recoded, or the first place is first recoded and then shifted to the second place, whereby it is ensured that all data has been coded by the first coding parameter or the second coding parameter before being shifted, making it more difficult to intercept plain text data.
