WPA makes all the versions of 802.11 devices (e.g.

WPA provides assurance to users of wifi network that their data remains protectedДЄnd only authorized persons are using the wifi network.

WEP VS WPA VS WAP PASSWORD

Once password is entered by users, TKIP protocol for periodic changing of the keys automatically.ДЇollowing 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 derivingДЇrom 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 AlgorithmДЇollowing 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.ДЇigure:2 WEP Decryption Process Block DiagramДЇollowing 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

WEP VS WPA VS WAP 64 BIT

Encrypt the plaintext using 64 bit key.

One process encrypts the plaintext while the other protects the data from any modification by intruders.ДЇollowing 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.ДЇigure:1 WEP Encryption Process Block Diagram.

WEP VS WPA VS WAP 32 BIT

It uses RC4 stream cipher to provide confidentiality and CRC polynomial of 32 bit size for data integrity.It uses 40 bit key for encryption (non-standard versions can use 128 bit or 256 bit) and 24 bit pattern for IV (Initialization Vector).WEP is symmetric as same keys are used for encryption and decryption.WEP, WPA and WPA2 are encryption algorithms used in WLAN wirelessДЇollowing are the features of WEP (Wired Equivalent Privacy):

WEP VS WPA VS WAP BLUETOOTH

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 ofДata 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. It describes WEP encryption and WEP decryption block diagram, mentions WEP drawbacks and 802.1x authentication used in WPA.
