I have a question about OT? we assume that sender has $m_0,m_1,m_2$, and $m_3$ and selects random $S_0, S_1, S_2, S_3, S_4, S_5$ and compute this statement than sends to receiver.
$C_0 = S_0 \oplus S_2 \oplus m_0$
$C_1 = S_0 \oplus S_3 \oplus m_1$
$C_2 = S_1 \oplus S_4 \oplus m_2$
$C_3 = S_1 \oplus S_5 \oplus m_3$
Can i change above statement into this?
$C_0 = S_0 \oplus S_2 \oplus m_0$
$C_1 = S_0 \oplus S_3 \oplus m_1$
$C_2 = S_1 \oplus S_2 \oplus m_2$
$C_3 = S_1 \oplus S_3 \oplus m_3$
