Video game security has always been a moving target, as consoles evolved to full-blown computing platforms locked down with layers of protection — but for every lock ever invented, there has always been someone determined to pick it.
List of talks I have presented in recent years, including links to slides and recording, when available:
In this article, we will deep dive into the major concepts behind random numbers and learn how to work with them on a Linux system.
In this article, we will learn how to debug the Linux kernel on an embedded Linux system with GDB.
TPM (Trusted Platform Module) is an international standard that enables trust in computing platforms in general, providing several security-related features for computer systems, including hashing, encryption, signing, random number generation, and many more!
Do you know there is a dedicated partition in the eMMC called RPMB that makes it possible to store data with integrity and authenticity support?
In this article, we will learn the basic concepts of SBOM (Software Bill of Materials) and how it can be generated and managed on embedded Linux with the Yocto Project.
In this article, we will learn how asymmetric-key encryption and digital signatures work from a practical perspective.
In this article, we will learn how symmetric-key encryption works from a practical perspective.
This article is an introduction to encryption for embedded Linux developers.
This article is an introduction to embedded Android from the perspective of an embedded Linux developer.
This is the second part of the article about embedded Linux security.
This article is going to be an introduction to embedded Linux security.
The Embedded Online Conference is an online conference for embedded systems, DSP, machine learning and FPGA engineers and it is starting today May 20th 2020.
Have you ever wondered how the Linux kernel is tested?
A Trusted Execution Environment (TEE) is an environment where the code executed and the data accessed is isolated and protected in terms of confidentiality (no one have access to the data) and integrity (no one can change the code and its behavior).
Last week, from February 25th to 27th in Nuremberg, Germany, we had another edition of Embedded World, the leading international fair for embedded systems.
The GNU Compiler Collection (GCC) provides several language features not found in ISO standard C.
Would it be a good idea to use containers on an embedded Linux system?
JTAG is a physical hardware interface that makes it possible, among other things, to extract the firmware image from electronic devices.
From February 25th to 27th in Nuremberg, Germany, we will have another edition of Embedded World, the leading international fair for embedded systems.
The best way to spend less time fixing bugs in software is not creating bugs in the first place, and a static analysis tool is perfect for this job.
A few days ago I decided to reverse engineer my router’s firmware image with binwalk.
The Embedded Online Conference is an online conference for embedded systems, DSP, machine learning and FPGA engineers.
AddressSanitizer (ASan) is an instrumentation tool created by Google security researchers to identify memory access problems in C and C++ programs.
Tracing is a useful technique to find bugs in software, and ftrace is the tracing framework built into the Linux kernel.
Container technology in general and Linux containers, in particular, have become increasingly popular in recent years.
Since version 4.8 the Linux kernel has a new interface based on character devices for accessing and managing GPIO lines in user space.
The slides and video of my talk at Embedded Linux Conference Europe 2019 are available.
One of the most effective ways to identify problems in applications that crash is through core dump analysis.
This is going to be my new blog about embedded systems development.
