How to attack on RC4 <p>Friends, I am working on a project where I need to crack as much keys as possible for RC4 algorithm. I would request you to go through RC4 algorithm before reading his question.</p> <p>I have given 50 different files (A00.data,A01.data...A49.data) each containing millions of lines. Every record of file contains 5 tuples</p> <ol> <li>Initial Vector[0]</li> <li>Initial Vector[1]</li> <li>Initial Vector[2]</li> <li>1st byte of PRGA algorithm</li> </ol> <p>Every key contains 8 bytes (3 bytes of Initial Vector-given + 5 bytes of secret key)</p> <p>How can I apply any specific attack (i.e RC4 ) and find the keys (5 secret bytes) from millions of rows in each file?</p>
