We propose to use parallelismtechniques to accelerate the computation of scalar multiplications, which is recognized as the mostcomputationally expensive operation on elliptic curves.

The SafeCurves project has been launched in order to catalog curves that are easy to securely cryyptographie and are designed in a fully publicly verifiable way to minimize the chance of a backdoor.

However, points on a curve can be represented in different coordinate systems which do not require an inversion operation to add two points.

They are also used in several integer factorization algorithms based on elliptic curves that have applications in cryptography, such as Lenstra elliptic-curve factorization.

Elliptic curves are applicable for key agreementdigital signaturespseudo-random generators and other tasks. I believe the NSA has manipulated them through their relationships with industry.

The size of the elliptic curve determines the difficulty of the problem.

Eliptique elliptic curves with given group order over large finite fields. Archived from the original PDF on As a result, several standard bodies published domain parameters of elliptqiue curves for several common field sizes. Recently, a large number of cryptographic primitives based on bilinear mappings on various elliptic curve groups, such as the Weil and Tate pairingshave been introduced.
