A formula for point addition in elliptic curves using affine representation and its implementation in FPGA is presented. The use of this new formula in hardware implementations of scalar multiplications for elliptic curve cryptography has the main advantages of: (i) reducing area for the ...
The successful application to elliptic curve cryptography of side-channel attacks, in which information about the secret key can be recovered from the observation of side channels like power consumption, timing, or electromagnetic emissions, has motivated the recent development of unified formulæ for...
Abstract In this paper we propose a new approach to point scalar multiplication on elliptic curves defined over fields of characteristic greater than 3. It is based on new point addition formulae that suit very well to exponentiation algorithms based on Euclidean addition chains. However finding sma...
EC Cryptography Tutorials - Herong's Tutorial Examples∟Geometric Introduction to Elliptic Curves∟Addition Operation on an Elliptic Curve This section describes the addition operation on an elliptic curve geometrically. The addition of points P and Q on an elliptic curve is a point R on the curve...

Ensuring uniform computation profiles is an efficient protection against some side channel attacks (SCA) in embedded systems. Typical elliptic curve cryptography (ECC) scalar multiplication methods use two point operations (addition and doubling) scheduled according to secret scalar digits. Euclidean additio...
If you want to perform point addition operation on an elliptic curve with tinyec Python library, you must do it in three steps. 1. Create the elliptic curve. For example: >>> import tinyec.ec as ec >>> s = ec.SubGroup(p=97,g=(0,0),n=1,h=1) >>> c = ec.Curve(a=2,b=3...
An efficient computation of scalar multiplication in elliptic curve cryptography can be achieved by reducing the original problem into a chain of additions and doublings. Finding the shortest addition chain is an NP-problem. To produce the nearest possible shortest chain, various methods were ...
