Abstract
In Elliptic Curve Cryptography (ECC), one performs a great number of modular multiplications. These are usually done by Montgomery Multiplication algorithm, which needs the operands to be preprocessed (namely, converted to the Montgomery Domain), which is normally done by an equivalent of a long division. We provide a method to perform this conversion by a single Montgomery multiplication on the raw data. The method is formulated for elliptic curve points represented in Jacobian coordinates but can be extended to other representations.
