WebWEP Security Flaw Even though cryptanalysis results as presented in the literature indicate certain weaknesses for RC4, the essential WEP security flaws are NOT due to the weakness of RC4. Actually, we will see that the WEP security flaws still exist even though RC4 is replaced with a stronger algorithm. Professor Guang Gong Lecture 6-c/7. WebRC4 Encryption RC4 is an encryption algorithm that was created by Ronald Rivest of RSA Security. It is used in WEP and WPA, which are encryption protocols commonly used on …
WebWEP uses the RC4 encryption algorithm, which is known as a stream cipher. A stream cipher operates by expanding a short key into an infinite pseudo-random key stream. The sender … http://www.opus1.com/www/whitepapers/whatswrongwithwep.pdf
WebOur main result is a practical key recovery attack on RC4 when an IV modifier is concatenated to the beginning of a secret root key to generate a session key. As opposed to the WEP attack from [FMS01] the new attack is applicable even in the case where the first 256 bytes of the keystream are thrown and its complexity grows only linearly with ... WEP was included as the privacy component of the original IEEE 802.11 standard ratified in 1997. WEP uses the stream cipher RC4 for confidentiality, and the CRC-32 checksum for integrity. It was deprecated in 2004 and is documented in the current standard. Standard 64-bit WEP uses a 40-bit key (also known as WEP-40), which is conca…
