Initialization Vector (IV) is one of the inputs to the WEP encryption algorithm. Therefore WPA was also based on that mechanism, just with a few advancements. A lot of wireless cards did not support the new AES (at that time), but all of them were using RC4 + TKIP. WPA was introduced just as a staging mechanism for smooth transition to WPA2. In order to enhance the security, WPA2 was invented with strong encryption model (AES) and a very strong authentication model based on 802.1x (or PSK).
#Wep vs wpa vs wpa2 algorithm crack
This is the biggest drawback of the implementation that leads to WEP being crack able within a few minutes, using the tools that anyone can have installed on their PCs. It is based on RC4 algorithm and 24 bits of Initialization Vector (IV). WEP was the first wireless "secure" model that was supposed to add authentication and encryption.

cracking the password during initial 4-way handshake (assuming that it's relatively short password <10 characters) Initialization Vector (IV) collision attack.The biggest difference between those three, are the security model they can provide. There are three widely known security standards in the world of wireless networking. The ones that you will most likely meet (in some form) on the wireless networks are RC4 and AES. The most common encryption algorithms are collected in the following table − Encryption Algorithm Stream Cipher − It converts plaintext into cyphertext in a bit-by-bit fashion.īlock Cipher − It operates on the fixed-size blocks of data.
To start speaking about wireless encryption, it is worth saying that there are 2 types of encryption algorithms: Stream Cipher and Block Cipher. Is that risk big enough, to stop using algorithm "X" for encryption? I doubt it, the information to be protected might be outdated at that point of time. All the algorithms that we use every day may be broken, but what is its likelihood of this happening with current technology and time?įor example, it might take around eight years to break encryption "X" using new super-fast computers. To be honest with you guys - there is no fully secure encryption scheme. And, to protect the information efficiently, it must be encrypted in a way that would not allow an attacker to decrypt it. Some information is too valuable, not to be protected.
Every time you access your web bank or mailbox, most often when you log in to any type of web page, or create a VPN tunnel back to your corporate network. Nowadays, we use encryption every single day, without even noticing. In general, encryption is the process of transforming the data, into some kind of cyphertext that would be non-understandable for any 3 rd party that would intercept the information.
