Building Tensorflow from source on Ubuntu 16.04LTS for maximum performance:

TensorFlow is now distributed under an Apache v2 open source license on GitHub.

On Ubuntu 16.04LTS+:

Step 1. Install NVIDIA CUDA:

To use TensorFlow with NVIDIA GPUs, the first step is to install the CUDA Toolkit as shown:

PicoCTF 2017: ECC2

A 1064CBread Writeup

Problem

In the file handout.txt, we are given the following parameters for an elliptic curve:

• y^2 = x^3 + A*x + B mod M -- the curve equation
• M -- the modulus of the curve

Elliptic Curve Cryptography (ECC)

Abstract

ECC is about a group created via:

• a 2-dimension elliptic curve: an equation with unknowns x and y
  • every Elliptic Curve follows this formula: y² + a₁ x y + a₃ y = x³ + a₂ x² + a₄ x + a₆ (for some specified a₁, a₂, a₃, a₄, a₆)
  • actually, it can be shorten to this y² = x³ + a x + b (short weierstrass form) in practice because the characteristic (order of a prime field) 2 and 3 points in prime fields (except for binary (GF(2^x)) and GF(3^x) curves)

• a curve of characteristic 2 (defined over GF(2^x)) can be simplified to y² + xy = x³ + ax² + b
