  2. Wired Equivalent Privacy - Wikipedia

    In Shared Key authentication, the WEP key is used for authentication in a four-step challenge–response handshake: The client sends an authentication request to the access point. The access point replies with a clear-text challenge. The client encrypts the challenge-text using the configured WEP key and sends it back in another authentication ...

    WEP used the RC4 algorithm for encrypting data, creating a unique key for each packet by combining a new Initialization Vector (IV) with a shared key (it has 40 bits of vectored key and 24 bits of random numbers). Decryption involved reversing this process, using the IV and the shared key to generate a key stream and decrypt the payload.

    The main purpose to implement TKIP was that the algorithm should be implementable within the capabilities of most of the old devices supporting only WEP. The initial authentication process is carried out either using a pre-shared key (PSK), or following an EAP exchange through 802.1X (known as EAPOL, which requires the presence of an ...

    WPA2 has been found to have at least one security vulnerability, nicknamed Hole196. The vulnerability uses the WPA2 Group Temporal Key (GTK), which is a shared key among all users of the same BSSID, to launch attacks on other users of the same BSSID. It is named after page 196 of the IEEE 802.11i specification, where the vulnerability is discussed.

  6. Pre-shared key - Wikipedia

    en.wikipedia.org/wiki/Pre-shared_key

    Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one end, without the knowledge of anyone at the other. There are several tools available to help one choose strong passwords, though doing so over any network connection is inherently unsafe as one cannot in general know who, if ...

    en.wikipedia.org/wiki/IPhone_SE_(2nd_generation)

    The second-generation iPhone SE (also known as the iPhone SE 2 or the iPhone SE 2020) is a smartphone developed and marketed by Apple Inc. It is part of the 13th generation of the iPhone, alongside the iPhone 11 and 11 Pro/Pro Max models. Apple announced it on April 15, 2020, coinciding with the discontinuation of the iPhone 8 and 8 Plus.

  8. 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.

  9. CCMP (cryptography) - Wikipedia

    en.wikipedia.org/wiki/CCMP_(cryptography)

    CCMP uses CCM that combines CTR mode for data confidentiality and cipher block chaining message authentication code (CBC-MAC) for authentication and integrity. CCM protects the integrity of both the MPDU data field and selected portions of the IEEE 802.11 MPDU header. CCMP is based on AES processing and uses a 128-bit key and a 128-bit block size.
