While it certainly improved on the weaknesses of WEP, TKIP eventually proved vulnerable to new attacks that extended previous attacks on WEP. Unfortunately, in order to preserve compatibility with the existing hardware that WPA was meant to вЂњpatch,вЂќ TKIP retained the use of the same underlying encryption mechanism as WEP вЂ“ the RC4 stream cipher.

If the access point receives an invalid MAC twice within a minute, the attempted intrusion can be countered by changing the key an attacker is trying to crack. In TKIP, an invalid MAC can also trigger rekeying of the session key. Sometimes known as a checksum, a MAC provides a cryptographic way to verify that messages havenвЂ™t been changed.

TKIP also implements other measures, such as a message authentication code (MAC). Each packet sent has a unique temporal 128-bit key, (See? Descriptive!) that solves the susceptibility to related-key attacks brought on by WEPвЂ™s shared key mashing. Ratified in a 2004 IEEE standard, Temporal Key Integrity Protocol (TKIP) uses a dynamically-generated, per-packet key. However, WPA first started out with another, more descriptive name. The name Wi-Fi Protected Access (WPA) certainly sounds more secure, so thatвЂ™s a good start. Wi-Fi Protected Access (WPA)ДЄ new, interim standard sought to temporarily вЂњpatchвЂќ the problem of WEPвЂ™s (lack of) security.

While some devices came to offer 152-bit or 256-bit WEP variants, this failed to solve the fundamental problems of WEPвЂ™s underlying encryption mechanism.

In the case of 128-bit WEP, your Wi-Fi password can be cracked by publicly-available tools in a matter of around 60 seconds to three minutes. Initialization Vector (IV): fixed-size input to a low-level cryptographic algorithm, usually random.Д¬ombined with the use of RC4, this left WEP particularly susceptible to related-key attack. WEP didnвЂ™t help matters either by simply concatenating the key with the initialization vector вЂ“ which is to say, it sort of mashed its secret-sauce bits together and hoped for the best. (WhenвЂ™s the last time you changed your Wi-Fi password? Right.) WEP employs a single shared key among its users that must be manually entered on an access point device. This cipher gained popularity due to its speed and simplicity, but that came at a cost. WEPвЂ™s underlying encryption mechanism is the RC4 stream cipher. The small key size resulted in being easier to brute-force, especially when that key doesnвЂ™t often change. Though this was later lifted to 128-bit, even this form of encryption offered a very limited possible key size. Government restrictions on the export of cryptographic technology caused access point manufacturers to limit their devices to 64-bit encryption. Governments reacted by attempting to keep their best secret-sauce recipes at home.ДЄround the time of WEP, U.S.

Wired Equivalent Privacy is a deprecated security algorithm from 1997 that was intended to provide equivalent security to a wired connection. LetвЂ™s explore what makes these four acronyms so different, and how you can best protect your home and organization Wi-Fi.
