Multichannel Encryption Based on Fractional Hilbert Transform
Zhao Li-feng · Modern Electronics Technique · 2011
The SSB communication based on the fractional Hilbert transform can use fracational rotation angle as the encryption key at the same time,so as to ensure the communications security effectively.But this technique can only use one encryption key.In order to increase the cryptographic key space for the securer system,a method of the shunting processing for the multi-channel filter set is introduced.It can also reduce the computation complexity.
