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. WebbThe Tonelli-Shanks algorithm is used (except for some simple cases in which the solution is known from an identity). This algorithm runs in polynomial time (unless the … how are lions adaptive

"WebbThis algorithm needs less number of group operations but storage should be greater. This algorithm is described as follows. Set n where n is the group order and write the unknown Discrete Logarithm as x = qm + r, 0 r < m. Thus r is the remainder and q is the quotient of the division of x by m. The Baby-step Giant-step algorithm calculates " - Shanks algorithm
