Hacker News 的讨论集中在一篇题为“什么是椭圆曲线?”的文章上。这篇文章发表在 onlynv.dev,因为它对这一数学概念的解释通俗易懂,即使是 12 到 15 岁的学生也能理解,而受到了称赞。评论者 “tamad” 预计他们的学生会觉得这篇文章很有趣。 另一位用户 “Muromec” 指出了椭圆曲线 Diffie-Hellman(ECDH)密码学中引人入胜的抽象层次。他们指出,该算法作用于曲线上的点,而这些点有其独特的数学规则。此外,曲线本身是在伽罗瓦域 (GF) 上定义的,伽罗瓦域也有其自身的数学结构。这种分层方法带来了引人入胜且错综复杂的学习体验。 帖子还包含了六月在旧金山举办的 AI 初创公司学校的广告。

    What the hell is an elliptic curve? (onlynv.dev)

    This is a simple explanation of an interesting and useful mathematical application my 12-15 yo students can conceptually grab onto. Good to have, they’ll enjoy it.


    ECDH is an amazing example of layers of abstraction (and not just indirection) -- you have an algorithm working on points on the curve, which have their own math, but the curve is definef over GF which have their own math. Having to deal with that was interesting experience.
