Elliptic Curve Cryptography - Extension Fields


An introduction to the pairing of points on elliptic curves. Point pairing normally requires curves over an extension field because the structure of an elliptic curve has two independent sets of points if it is large enough. The rules of pairings are described in a general way to show they can be useful for verification purposes.

Software is free and can right any wrong

Colin Walls

Software changes are so much easier than hardware modifications, so the temptation is always to take this approach to fixing bugs. This may not always be a good idea.

Creating a Hardware Abstraction Layer (HAL) in C

Jacob Beningo

In my last post, C to C++: Using Abstract Interfaces to Create Hardware Abstraction Layers (HAL), I discussed how vital hardware abstraction layers are and how to use a C++ abstract interface to create them. You may be thinking, that’s great for C++, but I work in C! How do I create a HAL that can easily swap in and out different drivers? In today’s post, I will walk through exactly how to do that while using the I2C bus as an example.

Elliptic Curve Cryptography - Key Exchange and Signatures


Elliptic curve mathematics over finite fields helps solve the problem of exchanging secret keys for encrypted messages as well as proving a specific person signed a particular document. This article goes over simple algorithms for key exchange and digital signature using elliptic curve mathematics. These methods are the essence of elliptic curve cryptography (ECC) used in applications such as SSH, TLS and HTTPS.

Elliptic Curve Cryptography - Security Considerations


The security of elliptic curve cryptography is determined by the elliptic curve discrete log problem. This article explains what that means. A comparison with real number logarithm and modular arithmetic gives context for why it is called a log problem.

Handling Translations in an Embedded Project

Mattia Maldini

A brief walkthrough on how to handle human language translations in a low level C application. Some options are listed, each with advantages and disadvantages laid out.

Elliptic Curve Cryptography - Basic Math


An introduction to the math of elliptic curves for cryptography. Covers the basic equations of points on an elliptic curve and the concept of point addition as well as multiplication.

What does it mean to be 'Turing complete'?

Nathan Jones

The term "Turing complete" describes all computers and even some things we don't expect to be as powerful as a typical computer. In this article, I describe what it means and discuss the implications of Turing completeness on projects that need just a little more power, on alternative processor designs, and even security.

Mastering Modern FPGA Skills for Engineers

Lance Harvie

In the rapidly evolving tech industry, engineers must acquire proficiency in modern FPGA skills. These skills empower engineers to optimize designs, minimize resource usage, and efficiently address FPGA design challenges while ensuring functionality, security, and compliance.
