A KRACK attack can gain access during the вЂњhandshakeвЂќ - the moment a network authenticates a device connection - leaving a victimвЂ™s passwords and other data vulnerable to interception. It uses the AES cipher, an encryption process that would take billions of years for even an advanced computer to break.Д«ut WPA2 also has its security flaws. The WPA2 security protocol increased the complexity of its predecessor (WPA) and has been the standard for network security for over a decade. Unless users and network admins created strong passwords, data was vulnerable.Д¬omparing WPA vs WEP, the security benefits of WPA were significant - but WPAвЂ™s own flaws quickly became apparent.

The complexity of the algorithm can now be overcome by modern processing power. TKIP has proved vulnerable and can be easily hacked. Increased the complexity of security keys and their authentication. Introduced TKIP, or dynamic key encryption, which regularly changes the network access key.ДЄll devices on the network recognize the new key when itвЂ™s generated. AES found widespread adoption with WPAвЂ™s successor, WPA2, which weвЂ™ll discuss in the next section.

Security experts quickly discovered that TKIP could be cracked with even small amounts of data.ДЄs a result, a replacement cipher (or encryption algorithm) to WEP and WPAвЂ™s RC4 cipher was crowdsourced to cryptographers around the world, with the Belgian-made AES cipher proving to be the most secure during the competitive selection process. TKIP created a dynamic security environment, but it still wasnвЂ™t enough.

That way, hackers can no longer crack the key by collecting transmitted data over a long period of time. Becoming the standard in 2003, WPA encrypts the network access key dynamically, by changing it regularly with TKIP (Temporal Key Integrity Protocol). WPA (Wi-Fi Protected Access) security was designed to address many of the problems that emerged with WEP. Too many security holes have been discovered over the years. Part of the key was transmitted as easily decipherable plaintext. Used a static encryption key, which had to be changed manually and updated on each individual machine to ensure the security benefits of later protocols. WEP protected against man-in-the-middle attacks. When it was introduced, the encryption algorithm was complex enough to keep unfamiliar users out. It aimed to equal the security benefits of wired internet connections. Most devices recognize WEP, meaning it was simple to set up and use. The WEP security protocol was retired in 2004, so systems still using it should be updated. Now, itвЂ™s a trivial matter for even a consumer-grade computer to run the calculations needed to decrypt a WEP key. When WEP security was introduced, the 64- or 128-bit string was difficult to crack, creating a formidable wall between a user network and hackers trying to intercept wireless signals.

If one user is compromised, everyone on the network is.

Introduced in 1997, WEP uses a single key to ensure the security of an entire network. WEP security encrypts with a static key - one of the biggest reasons itвЂ™s no longer considered secure. Wired Equivalent Privacy (WEP) used to be the standard form of encryption, but itвЂ™s no longer secure, because computing power has improved and hackers can now crack it easily. The most recent protocols, including the newest WPA3 protocol, have proved very robust, with workarounds much harder for hackers to pull off. Each protocol uses a different kind of encryption to strengthen network security. The most common wireless security protocol types today are WEP, WPA, and WPA2. LetвЂ™s take a look at the different Wi-Fi security types implemented over the years. The best Wi-Fi security protocol will prevent router hacking and help you browse safely on public Wi-Fi. Thankfully, encryption standards have improved over the years, minimizing vulnerabilities and neutralizing threats. Unless youвЂ™ve got the best wireless security, any device online can be hacked. Without strong security protocols, you can accidentally leave passwords and even online payment information available for someone on the same network whoвЂ™s snooping for personal details. Public Wi-Fi networks (like those in restaurants and cafes) can leave you exposed, too. And if there are vulnerabilities in your router, your DNS settings could be hijacked, among other problems, and you could end up unknowingly visiting fake or dangerous websites. Your internet router isnвЂ™t just the place where you can boost your homeвЂ™s Wi-Fi strength.
