"Webb2.1 The Classical Baby-Step Giant-Step Algorithm One of the most famous and generic algorithms dealing with the discrete loga-rithm problem is the so-called Baby-Step Giant-Step algorithm. Introduced by Shanks [1], it is a time-memory trade-oﬀ with time complexity O √ n group multiplications. The algorithm works as follows. Let m = ⌈n1/2⌉. " - Shanks algorithm

The … WebbLast week, we saw Tonelli-Shanks algorithm to compute square roots modulo an odd prime pin O(log3 p). The ﬁrst step of this exercise is to design an algorithm to compute square roots modulo pv, for some v 2 and odd prime p. 1.Let x2(Z=pvZ) . Show that x2 1 [pv] if and only if x 1 [pv]. Let ’be the Euler totient function.

WebbThe standard method to generate a random point on an elliptic curve is to choose a random x -coordinate and solve a quadratic equation for y. (If no solution exists, a new x -coordinate is chosen.) For odd characteristics, this can be done once one is able to find square roots of elements. Webb23 jan. 2024 · Many privacy preserving blockchain and e-voting systems are based on the modified ElGamal scheme that supports homomorphic addition of encrypted values.
