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

摘要

The present invention relates to a device for safe data transmission over Z channels employing CDMA, which comprises:
±.
means for symbol re-encoding through expansion thereof;
².
means for encoding using error correction techniques;
Ç.
means for transmission using Time-Hopping CDMA based on a nonlinear pseudo-random generator with secure password and Bloom filters, and
´.
means for channel modulation, both optical and wireless. The invention is based on the surprising fact that channel utilization can be substantially improved in the case of data transmission over Z channels employing CDMA, by the use of symbol re-encoding through expansion thereof, error correction techniques and bit encoding according to a nonlinear pseudo-random generator with secure password.
