WebIn Sage, an elliptic curve is always specified by (the coefficients of) a long Weierstrass equation y 2 + a 1 x y + a 3 y = x 3 + a 2 x 2 + a 4 x + a 6. INPUT: There are several ways to construct an elliptic curve: EllipticCurve ( [a1,a2,a3,a4,a6]): Elliptic curve with given a -invariants. The invariants are coerced into a common parent.

In this work, an elliptic curve cryptography (ECC) processor is proposed to be used in the Internet of Things (IoT) devices. The ECC processor is designed based on Edwards curves defined over the finite prime fields G F ((2 13-1) 13), G F ((2 17-1) 17), and G F ((2 19-1) 19).Modular multiplication in the proposed ECC processor is carried out in the … bright star cinema

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:
