    en.wikipedia.org/wiki/Wired_Equivalent_Privacy

    WEP was included as the privacy component of the original IEEE 802.11 [8] standard ratified in 1997. [9] [10] WEP uses the stream cipher RC4 for confidentiality, [11] and the CRC-32 checksum for integrity. [12] It was deprecated in 2004 and is documented in the current standard. [13] Basic WEP encryption: RC4 keystream XORed with plaintext

    WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP. [4]

    The four-way handshake [8] is designed so that the access point (or authenticator) and wireless client (or supplicant) can independently prove to each other that they know the PSK/PMK, without ever disclosing the key. Instead of disclosing the key, the access point (AP) and client encrypt messages to each other—that can only be decrypted by ...

  6. Temporal Key Integrity Protocol - Wikipedia

    en.wikipedia.org/wiki/Temporal_Key_Integrity...

    Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
