Hello List,
I want to embed AES-128 in the DV mode of SM1000 for half duplex mode. For that I started studying DV portion of code in sm1000_main.c. But it seems very complex to traverse each function. As FEC is also implemented so I need FEC to be implemented after encryption. Can anyone guide me about how to proceed? What are the timing constraints for encrypting a 16 byte frame?

Thank you in advance for your help.

Sir
with all respects..

If you are going to want to implement this sort of thing, and all the
complexity that goes with it, to have any chance of success, you are
going to have to be able to figure out questions like you have asked...

Yes, you will need to transverse each function , step by step. It will
take time and patience.

What is your end use application ? Why encryption ?

regards

Hi Glen
Thanks for your reply.
Yes I am working on it. I asked if someone else did the same sort of work before can help me out.
As far as the end use application is concerned, I think sm1000 can be used with any analog radio for DV and encryption add-on. What do you think?

Regards
Nauman

Hi Nouman,

We would like to be able to export the SM1000 without government
restrictions, for civil use by Amateur Radio operators, and the existence
of an NRTC-developed firmware for the device to support the Pakistan
military could cause us all manner of legal issues with our own
governments. Obviously we can't stop you from using Codec2 in your own
hardware device.

Thanks

Bruce
