  • Page 76 According to the IEEE 802.11 standard, Wired Equivalent Privacy (WEP) is intended to provide “confidentiality that is subjectively equivalent to the confidentiality of a wired local area network medium and that does not employ cryptographic techniques to enhance privacy.” WEP relies on a secret key that is shared between a mobile station and an access point. WEP uses the RC4 stream cipher invented by RSA Data Security.
