Colin O'Flynn, Auteur | 2019"It's not so easy to keep with all the new security feature on the latest and greatest embedded processors - especially while you're busy focusing on the more fundamental and unique aspects of your design. In this article, Colin helps out by examining the new processor cores using TrustZone-M, a ...Article : texte imprimé
Colin O'Flynn, Auteur | 2019"Many products use USB, but have you ever considered there may be a critical security vulnerability lurking in your USB stack ? In this article, Colin walks you through an example product that could be broken using electromagnetic fault injection (EMFI) to perform this attach without even removing the device ...Article : texte imprimé
Colin O'Flynn, Auteur | 2019"Side-channel power analysis is a method of breaking security on embedded systems, and something Colin has covered extensively in his column. This time Colin shows how you can prove some of the fundamental assumptions that underpin side-channel power analysis. He suses the open-source ChipWhisperer project with Jupyter notebooks for ...Article : texte imprimé
Colin O'Flynn, Auteur | 2019"Low-cost microcontrollers integrate many powerful peripherals. You can even perform data capture directly to internal memory. In his article, Colin uses the ChipWhisperer-Nano as a case study in how you might use such features that would otherwise require external programmable logic." (Extrait de Circuit Cellar n°342)Article : texte imprimé
Colin O'Flynn, Auteur | 2018"This month Colin summarizes a few interesting presentation from the Black Hat conference in Las Vegas. He walks you through some attacks on bitcoin wallets, x86 backdoors and side channel analysis work-these and other interesting presentations from black Hat." (Extrait de Circuit Cellar n°340)Article : texte imprimé
Colin O'Flynn, Auteur | 2018"Microcontroller fuse bits are used to protect code from being read out. How well do they work in practice ? Some of them have been broken recently. Here, Colin takes you through the details of such an attack to help you understand the realistic threat model." (Extrait de Circuit ...Article : texte imprimé
Colin O'Flynn, Auteur | 2018"How do you verify the security of microcontrollers ? MCU manufacturers often make big claims, but sometimes it is in your best interest to verify them yourself. In this article, Colin discusses a few threats against code readout and looks at verifying some of those claimed levels." (Extrait de ...Article : texte imprimé
Colin O'Flynn, Auteur | 2018"The Spectre attack might be the first time the words "side-channel attacks" made mainstream news. Here, Colin provides a brief overview of that speculative execution side-channel attack. A quick overview of cache-timing attacks and return oriented programming is also included." (Extrait de Circuit Cellar n°334)Article : texte imprimé
Colin O'Flynn, Auteur | 2018"Prototyping embedded systems is an important part of the development cycle. But when many revisions are needed, the process gets tedious. In this article, Colin presents an open-source tool that helps you assemble prototype devices by making the placement process even easier." (Extrait de Circuit cellar n°332)Article : texte imprimé
Colin O'Flynn, Auteur | 2018"Colin returns to the topic of fault injection security attacks. To kick off 2018, he summarizes information about five different fault injection attack stories from 2017 - attacks you should be aware of as an embedded designer." (Extrait de Circuit Cellar n°330)
