| Jul 2, 2020 at 12:12 | comment | added | braincoke | Do you have any knowledge of a method to hash a point into an elliptic curve that would be simple enough and secure for this use case ? | |
| Jul 2, 2020 at 12:10 | comment | added | braincoke | Wow, I did not see that. This is a great answer. I don't understand your final note about Alice being able to derive what her exchanged value would have been though. But I do understand the concept, Alice computes the inverse of $h(m_1)$ to reuse Bob's answer and perform an offline brute force attack. | |
