Shanks algorithm
Webbbe done in probabilistic polynomial time using the Tonelli-Shanks algorithm. Thanks to the Skalba equality, the authors of [10] show how to do it determinis-tically using a modi cation of the Tonelli-Shanks algorithm, in time O(log4 q). We note that for q= 3 mod 4, computing a square root is simply an exponen-tiation, which takes O(log3 q). Webb具体的な計算. p − 1 = 2 m Q とする。. ( m ≥ 0, Q は奇数) まず平方非剰余となる z を一つ見つける。.

We’ll now describe the algorithm used to solve DLP, which is, due to Daniel Shanks, called Baby step – Giant step. This algorithm can be applied to any finite cyclic abelian group. Depending on the use case some modifications are possible. Asume we have public cyclic group G = g of prime order p.

Webb30 juni 2024 · Given a square u in Z p and a non-square z in Z p, we describe an algorithm to compute a square root of u which requires T + O ( n 3 / 2) operations (i.e., squarings and multiplications), where T is the number of operations required to exponentiate an element of Z p to the power ( m − 1) / 2. This improves upon the Tonelli-Shanks (TS ...
