This implementation of the secp256r1 elliptic curve uses two techniques to improve the performance of the operations. 1. All coordinates are stored in Jacobian form, (X/Z^2, Y/Z^3, Z), which removes the need for division operations during point addition or doubling. The points are converted at the start of the computation, and converted back at the end. 2. All values are transformed to Montgomery form, to allow for faster modular multiplication using the Montgomery modular multiplication method. This means that all coordinates have to be converted into this form, and back out of this form before returning them. |
