WPA provides assurance to users of wifi network that their data remains protectedĪnd only authorized persons are using the wifi network.
#WEP VS WPA VS WPA PSK PASSWORD#
Once password is entered by users, TKIP protocol for periodic changing of the keys automatically.įollowing are the features of WPA (Wi-Fi Protected Access): WPA personal type depends on pre-shared key or password entered by users in WPA enterprise type uses RADIUS server for authentication of users.

There are two types of WPA algorithm viz. WPA has been developed by the WiFi alliance. Moreover WPA changes the keys at regular intervals to provide more robust link. WPA help avoid this problem by automatically setting the keys after derivingįrom master key. This leads to easy access for the hacker to wifi link. The major problem with WEP compliant devices is that user either fails to activate WEP or do not change the default password. WPA algorithm as described below has beeen developed to overcome the drawbacks of WEP encryption algorithm. This leads to possibility by hacker to re-route the data to APs through some alternative un-authorized path or route. There is no way by which APs can authenticate the NICs. It uses smaller key size of length 40 bits and IV of length 24 bits are more prone to attacks.Analysis of captured traffic can reveal shared key used.Drawbacks of WEP Encryption Algorithmįollowing are the drawbacks of WEP encryption: If both new ICV and decoded matches received message is considered to be correct otherwise.The algorithm is verified for correctness by comparing new ICV with the one decoded from received data.New ICV is determined based on received plaintext.RC4 algorithm is applied to cipher text with key sequence to produce original.It is used to decrypt the incoming message. IV value from incoming message is used to generate key sequence.This is done to prevent data modification by unauthorized person.įigure:2 WEP Decryption Process Block Diagramįollowing are the steps involved in WEP decryption process: RC4 algorithm is applied on plain text, ICV and key sequence in order to generate cipher text.The 4 bytes IV value is added with ciphertext before transmission.The resulting encrypted bytes have same length as input data bytes. The PN key sequence is XORed with data.As shown RC4 uses key value as initial seed and generates PN key sequence.Here 64 total bits consists of 40 bit secret key and 24 bit

Encrypt the plaintext using 64 bit key.One process encrypts the plaintext while the other protects the data from any modification by intruders.įollowing are the steps involved in WEP encryption process: There are two processes being applied to plaintext in WEP. The fig-1 depicts WEP encryption procedure. The WEP encryption and WEP decryption process uses simple XOR as explained below.įigure:1 WEP Encryption Process Block Diagram.

Such as zigbee, GSM, WLAN, Zwave, bluetooth etc. There are various wireless networks based on different standard based technologies

Inspite of many security mechanisms incorporated in wireless, it can never be 100% secure mode ofĭata transmission. Wireless security has been a concern since long due to open air transmission medium used by it. It provides link to AES encryption used in WPA2 algorithm.
