Thai SEC approves four crypto firms despite Zipmex woes

Thailand’s regulators are still approving crypto companies despite one of its largest ones suspending withdrawals.

Security of Reusing a One-Time Pad with Complement Messages with Errors

Let’s say I have two binary messages ($m_0$ and $m_1$) of length $n$ which are bitwise complements of each other such that $$m_0 xleftarrow{r} {0,1}^n text{ and } m_1 = overline{m_0}$$ If I perform a one-time pad encryption of $m_0$ and $m_1$ with the same key, I would only leak that the messages are bitwise::Listen

Let’s say I have two binary messages ($m_0$ and $m_1$) of length $n$ which are bitwise complements of each other such that $$m_0 xleftarrow{r} {0,1}^n text{ and } m_1 = overline{m_0}$$

If I perform a one-time pad encryption of $m_0$ and $m_1$ with the same key, I would only leak that the messages are bitwise complements of each other (but not the contents of the $m_0$ or $m_1$).

Now my question is if $m_1$ has a bit-flip error. For example, there is an integer $0 < i < n$ where $m_1[i] = m_0[i]$

Does this error leak the key at index $i$? Does this error leak either message at index $i$?

My intuition says no because we are performing a one-time pad of the same message at index $i$ but I may be missing something…
