Which of the following is a WEP weakness that makes it easy to Inject arbitrary clear text packets onto a WEP network?
The primary weakness that makes it easy to inject arbitrary clear text packets onto a WEP network is the cryptographically weak CRC32 checksum. The RC4 algorithm itself, despite being a stream cipher, is not the core weakness; it is the combination of RC4 with WEP’s flawed implementation, particularly the use of a weak CRC32 checksum for message integrity, that exposes WEP networks to packet injection attacks.
C, RC4 is a weak algorithm The primary weakness of Wired Equivalent Privacy (WEP) that allows for easy injection of arbitrary clear text packets onto a WEP network lies in its flawed implementation of the RC4 encryption algorithm, particularly regarding the handling of initialization vectors (IVs). This weakness can be detailed as follows:
