WebJul 30, 2024 · 基本概念理解: 1. P, Q, R在一条线上【R (x,y)】⇒ R' (x,-y) = P+Q 2. P+Q+Q = 0 ⇒ P+2Q = 0 ⇒ P' = 2Q or P+Q = Q' 3. P+Q+0 = 0 ⇒ P+Q = 0 4. P+P+0 = 0 ⇒ 2P+0 = 0 ⇒ 2P = 0 EC中的加法公式: 当P≠Q: 当P=Q: EC乘法公式: 我们可以通过n次加法的形式解释n*P的乘法, 例如2*3 = 3+3 或者 3*2 = 2+2+2 但是这里有个弊端就是n值越大,这样算法的复杂度越高 … WebMay 10, 2024 · CryptoHack Mathematics Write-up CTFwrite-upCrypto Crypto Publish Date: 2024-05-10 Word Count: 1.1k Read Times: 6 Min Read Count: 作者: Gunjyo
