WebOct 16, 2024 · Solution 1: Safe primes structure (Intended) We obtain a nested power equation : p o w ( g, G x, n) = p o w ( g, G y, n). The first power of g gives : G x ≡ G y mod φ ( n)), and the second power of G gives y ≡ x mod φ ( φ ( n)) where φ is Euler function. From above equation, we have: WebSep 7, 2024 · It selects a random point G G on the curve E (\mathbb {Z}/pq\mathbb {Z}) E (Z/pqZ) and a random 128 bit number d d as the private key.

It means if we have a point (x0, y0) we need to check the equation y0^2 == x0^3 + a*x0 + b (where y^2 == x^3 + a*x + b is our Elliptic curve). If the equation does not hold (or we just don’t check it), the cryptosystem becomes vulnerable to Invalid curve …
