| 标题： | Z2kDH |
| 描述： | Or, more precisely: $\mathbb{Z}/2^k\mathbb{Z}^*$-Diffie-Hellman Sick of how slow it is to take the modulus of a large prime number? Tired of performing exponentiation over some weird group like ed25519? Just use the integers mod 2^k group! Efficient, reliable, doesn't require any hard math! |
