I am trying to extract an unknown key from a DMR system. If my notions are correct, to encrypt is done by a concatenation of the known key plus the initialization vector, to this concatenation is passed the KSA algorithm of RC4 and the result would be applied the PRGA algorithm, this would give us as a result a keystream to which is applied an XOR with the voice in clear. The problem I am facing is the following: Supposedly an XOR of the encrypted voice would have to be performed with... what? Supposedly it would be with the voice frame in clear? The next question is: if this gives me the keystream should I pass the PRGA and KSA algorithm to it in that order? and the result I imagine would be that concatenation of key and initialization vector. I do not know if these approaches are correct or I am wrong in my approach, I would need help to clarify this problem,
Thank you so much for your kind words! Your support and encouragement mean a lot to me, and I'll definitely keep making informative videos. Stay tuned for more content!
Plzz do such video very useful to many students who are wishing to learn
I will try my best
