    Weak Keys in RC4

    This is an archive of the original posts Andrew Roos made in 1995 to announce his discovery of weak keys in RC4. Even though most Wireless LAN access points avoid these keys since many years, this discovery eventually led to abandoning RC4 for use in WEP (“Wired Equivalent Privacy”) for Wi-Fi networks, as the privacy…
