DEVICE AND METHOD FOR THE SECURE TRANSMISSION OF DATA OVER Z CHANNELS USING CDMA

摘要

The invention relates to a device for the secure transmission of data over Z channels using CDMA, comprising: a) means for recoding symbols via the expansion thereof; b) encoding means using error correction techniques; c) transmission means using time-hopping CDMA based on a non-linear pseudo-random generator with a secure key and Bloom filters; and d) means for modulating both the optical and wireless channels. The invention is based on the surprising fact that the use of the channel can be substantially improved in the case of data transmission using CDMA on Z channels, by: recoding symbols via the expansion thereof, using error correction techniques and encoding the bits using a non-linear pseudo-random generator with a secure key.
