768 $P$ under the key $k$ as $E_k(P)$. In some modes there exists an initial vector denoted as $C_{-1}$.
784 C_i = E_k(P_i \oplus C_{i - 1})
793 C_{-1} = C_{-1} + 1\mbox{ }(\mbox{mod }2^W) \nonumber \\
794 C_i = P_i \oplus E_k(C_{-1})
804 C_i = P_i \oplus C_{-1} \nonumber \\
805 C_{-1} = E_k(C_i)
815 C_{-1} = E_k(C_{-1}) \nonumber \\
816 C_i = P_i \oplus C_{-1}
