Computer Science Before the introduction of IEEE 802.11i, the security scheme for IEEE 802.11 was Wired Equivalent Privacy (WEP). Assume that the initialization vector (IV) is not used in WEP. Instead, RC4 is applied using K as input and producing s as output. Assume RC4(K, n) is applied for each packet and that all packets have the same length. If an attacker intercepts a single packet with ciphertext C1 and also has a known plaintext/ciphertext pair (P2, C2). Show how the attacker can find the plaintext P1. You can make use of an example by assuming some random data is being encrypted.
