WEPplus, also known as WEP+, is a proprietary enhancement to WEP by Agere Systems (formerly a subsidiary of Lucent Technologies) that enhances WEP security by avoiding "weak IVs". [24] It is only completely effective when WEPplus is used at both ends of the wireless connection. As this cannot easily be enforced, it remains a serious limitation.
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 [2] WEP was superseded in 2003 by WPA, a quick alternative at the time to improve security over WEP.
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]
However, many applications that use RC4 simply concatenate key and nonce; RC4's weak key schedule then gives rise to related-key attacks, like the Fluhrer, Mantin and Shamir attack (which is famous for breaking the WEP standard). [25] Because RC4 is a stream cipher, it is more malleable than common block ciphers.
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 ...
A recent hearing by the U.S. House Ways and Means Committee’s Subcommittee on Social Security concluded that the WEP and GPO deny public servants “their hard-earned retirement benefits ...
The WEP and GPO provisions outline how Social Security deals with retirees who receive pensions. Under the WEP, Social Security benefits are reduced if you receive a pension from work, did not pay ...
The WEP reduces Social Security benefits for individuals who get a pension from a job that didn’t require them to pay taxes into the program (despite having worked other jobs that did), while ...
