Creating ciphertext in Wired Equivalent Privacy (WEP) protocol:

The WEP protocol appends an initialization vector (IV) to the symmetric shared key (KS) to form an encryption key. The WEP protocol XORs data bits with this key to produce cirphertext.

The key stream value provided is 1111000 and the data value provided is 10101100.

Consider IV=0. So, append IV to the key stream. 

The cipher text is calculated by performing the XOR operation between the key stream and data as follows:
