Realtime HDTV Encryption of CRL in 2003

Realtime Encryption of Uncompressed HDTV Movies of Historical CRL(Communications Research Laboratory) Advertisement in 2003. CRL was reorganized as National Institute of Information and Communications Technology (NICT) in April of 2004.
The monitor (left) showed decrypted HDV movie while the monitor (right) showed encrypted HDTV movie. Voice signals were
not encrypted and recorded from the original source.
Note 3: ChaosWare, Inc is the first and the last spin-off technology oriented venture company of CRL which is currently considered as the NICT first startup.

BTW, is this company still existing. If so, could we have the contact info ? Thanks in advance.

I am sorry. For some reasons that I don't think this is a full encryption. Because if that is the case then we should not be able to see any deterministic info on the back ground. We can clearly see the picture on the background. And I don't think this is a FPGA system due to I/O bottleneck. It must be some kind of ASIC (or a full silicon implementation). My inclination is still toward a simple overlay mask.. I could be wrong..

Encryption speed = 14.85Gbps=1.485Gbps*10 channel. This is based on our original algorithm using "digital chaos". 480bit key

stream cipher. Thanks for your comments.

Thank you for your comments. It is full data encryption based on stream cipher

(chaos algorithm). Stream keys are updated at each time of encryption. We also observe some kind of visual illusion for this kind of encryption demo.

I am sorry. I am not 100% sure..

I think it is just a additive mask. Not a full data rate encryption. Because I can still see the signal on the background. It is more like a mosaic thing.

Wouldn't you agree with my simple-minded observation ?

[WirelessAT]

I think your verbal caption is too general and full of lofty goals.

Would you be a little more specific about the

DEMO.

Thanks.

Nice Demo.

I do have some questions if you don't mind..

What is the overhead ? Is it based on PSK ? Do you use AES ? What is the strength ?

Thanks in advance.
