    RC4/ARC4/ARCFOUR is a fast, simple encryption algorithm developed in 1987 to implement byte-by-byte encryption using 64 or 128 bits long keys. RC4 is widely used in Transport Layer Security, Secure Sockets Layer, and the IEEE 802.11 WLAN standard.

    In RC4 encryption for the DMR system we use this protocol, after the use of the two algorithms KSA and PRGA resulting from applying them to the private key, plus the initialisation vector we get a keystream, the encryption as such is the result of performing an XOR of this keystream and the voice in clear, taking into account that in each super frame the initialisation vector is modified.
    The question is the following, if I have the encrypted voice, against which element should I perform this XOR to the encrypted voice if I do not know the key and therefore, the keystream.

    In key scheduling, initially we took j=0 for 1st step but what about j value in 2nd step while i=1. Mam

    In the second step, shouldn’t the i and j mod operations be 4 (i = (i+1) mod 4) as per your example or is it always 256 (i = (i+1) mod 256)? at 7:18
