The personal mode, WPA-PSK, uses preshared keys for simpler implementation and management among consumers and small offices. The enterprise mode, WPA-EAP, uses more stringent 802.1x authentication with the Extensible Authentication Protocol, or EAP. WPA has discrete modes for enterprise users and for personal use. In response, in 2003, the Wi-Fi Alliance released WPA as an interim standard, while the Institute of Electrical and Electronics Engineers (IEEE) worked to develop a more advanced, long-term replacement for WEP. The numerous flaws in WEP revealed the urgent need for an alternative, but the deliberately slow and careful processes required to write a new security specification posed a conflict. This characteristic, along with several other vulnerabilities - including problematic authentication mechanisms - makes WEP a risky choice for wireless security. However, the small size of the IV increases the likelihood that keys will be reused, which, in turn, makes them easier to crack. The key is combined with a 24-bit initialization vector (IV) in an effort to strengthen the encryption. The key must be manually entered and updated by an administrator. The standard originally specified a 40-bit, pre-shared encryption key - a 104-bit key was later made available after a set of restrictions from the U.S. WEP uses the RC4 stream cipher for authentication and encryption. Maxx in 2009 was traced back to vulnerabilities exposed by WEP, the Payment Card Industry Data Security Standard prohibited retailers and other entities that processed credit card data from using WEP. After a large-scale cyber attack executed against T.J. From the start, however, WEP lacked the strength necessary to accomplish this.Д¬ybersecurity experts identified several severe flaws in WEP in 2001, eventually leading to industry wide recommendations to phase out the use of WEP in both enterprise and consumer devices. Developed in the late 1990s as the first encryption algorithm for the 802.11 standard, WEP was designed with one main goal in mind: to prevent hackers from snooping on wireless data as it was transmitted between clients and access points (APs).
