#Wep vs wpa 2 encryption password#
For instance, WPA3-Personal provides encryption to users even if hackers crack your password after you connect to a network.įurthermore, WPA3 requires all connections to use Protected Management Frames (PMF). WPA3 picks up the slack and offers much greater security, while actively taking into account the oft-lacking security practices everyone is guilty of at times. The Key Reinstallation Attack (KRACK) is a direct attack on the WPA2 protocol and unfortunately undermines every Wi-Fi connection using WPA2.Įssentially, KRACK undermines a key aspect of the WPA2 four-way handshake, allowing a hacker to intercept and manipulate the creation of new encryption keys within the secure connection process.ĭan Price has detailed the KRACK attack and whether your router is insecure or not.Įven with the potential for a KRACK attack, the likelihood of someone using it to attack your home network is slim. The somewhat amusingly named KRACK attack is no laughing matter it is the first vulnerability found in WPA2. is an encryption protocol included as part of the IEEE 802.11i standard for wireless LANs (WLANs). WPA2 is a better version of security in wireless connections as compared to WPA. To address the shortcomings of WEP security, a new security protocol was introduced called TKIP or the Temporal Key Integrity Protocol.
The main difference between WPA and WPA2 is their security algorithm. TKIP remains part of the WPA2 standard as a fall back as well as to offer functionality for WPA-only devices. WEP was successful in providing an encrypted network, but as the technology was upgrading, hackers were able to hack through this encrypted network.

WPA2 also introduced the Counter Cipher Mode with Block Chaining Message Authentication Code Protocol (or CCMP, for a much shorter version!) to replace the now vulnerable TKIP.

AES is substantially stronger than RC4 (as RC4 has been cracked on multiple occasions) and is the security standard in place for many online services at the current time. WPA2 brought with it another raft of security and encryption upgrades, most notably the introduction of the Advanced Encryption Standard (AES) to consumer Wi-Fi networks. WPA, then, had a short run as the pinnacle of Wi-Fi encryption. The new TKIP WPA system recycled some aspects of the compromised WEP system and, of course, those same vulnerabilities eventually appeared in the newer standard. Cons: When rolled out onto WEP devices, TKIP can be exploited. TKIP encryption method is better than the fixed-key encryption used by WEP. Unfortunately, the TKIP WPA rollout had to take into account old WEP devices. Pros: Addresses security vulnerabilities of the original wireless security standard, WEP. TKIP itself was a big step forward in that it used a per-packet key system to protect each data packet sent between devices. The vulnerabilities centered on the introduction of the Temporal Key Integrity Protocol (TKIP).
