  • What then-known weaknesses in RC4 do you have in mind?

  • I don't get your meaning about key sizes, could you be more specific?

  • WEP does not re-use IVs.

WEP uses 24-bit IVs. Birthday paradox guarantees IV reuse.

Original WEP uses 40-bit key. This is already borderline broken, so any extra weakness moves us into trivially broken in seconds territory WEP occupies now.

RC4 weak key schedule.
