Basic WEP encryption: RC4 keystream XORed with plaintext. Standard 64-bit WEP uses a 40-bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the RC4 key. At the time that the original WEP standard was drafted, the U.S. Government's export restrictions on cryptographic technology limited the key ...
PIN method In which a PIN has to be read from either a sticker or display on the new wireless device. This PIN must then be entered at the "representant" of the network, usually the network's access point. Alternately, a PIN provided by the access point may be entered into the new device.
If the wrong PIN is entered more than three times, the SIM card will become locked. It can be unlocked by entering the PUK code provided by the mobile service provider, [1] which may be available on the SIM card's packaging, the contract, or provided by customer service after identity verification. After the PUK code is entered, the PIN must be ...
The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [45] Users have been urged to turn off the WPS feature, [46] although this may not be possible on some router models. Also, the PIN is written on a label on most Wi-Fi routers with WPS, which cannot be changed if compromised.
WEP is an old IEEE 802.11 standard from 1997. [1] It is a notoriously weak security standard: the password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. [2] WEP was superseded in 2003 by WPA, a quick alternative at the time to improve security over WEP.
The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
Screenshot of Android Wi-Fi configuration with the Security set to "Enhanced Open" Opportunistic Wireless Encryption (OWE) is a Wi-Fi standard which ensures that communication between a public hotspot and end devices is protected from other end devices.
A smart card (SC), chip card, or integrated circuit card (ICC or IC card), is a card used to control access to a resource.It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. [1]
