My Smartphone Knows What You Print

Abstract

Additive manufacturing, also known as 3D printing, has been increasingly applied to fabricate highly intellectual property (IP) sensitive products. However, the related IP protection issues in 3D printers are still largely underexplored. On the other hand, smartphones are equipped with rich onboard sensors and have been applied to pervasive mobile surveillance in many applications. These facts raise one critical question: is it possible that smartphones access the sidechannel signals of 3D printer and then hack the IP information? To answer this, we perform an end-to-end study on exploring smartphone-based side-channel attacks against 3D printers. Specifically, we formulate the problem of the IP side-channel attack in 3D printing. Then, we investigate the possible acoustic and magnetic side-channel attacks using the smartphone built-in sensors. Moreover, we explore a magnetic-enhanced side-channel attack model to accurately deduce the vital directional operations of 3D printer. Experimental results show that by exploiting the side-channel signals collected by smartphones, we can successfully reconstruct the physical prints and their G-code with Mean Tendency Error of 5.87% on regular designs and 9.67% on complex designs, respectively. Our study demonstrates this new and practical smartphone-based side channel attack on compromising IP information during 3D printing.

SoK: Identifying and Unifying Limitations, Security Threats & Vulnerabilities in Additive Manufacturing

“…Song et al [54] proposed an attacking strategy that is similar to Faruque et al [21] in terms of acoustic emission. But there are several differences between those works.…”

“…Firstly, in [21], they used a professional audio recorder to record the audio. But, in [54], the authors used sensors available on smartphones. Secondly, instead of using a single side channel, the of [54] used magnetic and acoustic emanations.…”

“…But, in [54], the authors used sensors available on smartphones. Secondly, instead of using a single side channel, the of [54] used magnetic and acoustic emanations. This approach has a more precise result than the Gupta et al [29] demonstrated an anti-counterfeit system based on compensatory manufacturing conditions and pairing defecting model features.…”

Aplicação Da Impressão 3d Em Projeto De Extensão No Ensino Superior Em Hospital De Tratamento De Câncer

“…Existem algumas vantagens no uso da impressão 3D em comparação aos processos de fabricação tradicionais, entre eles: (i) eficiência -produção rápida e econômica, com baixas quantidades de material residual; (ii) criatividade -ideal para confecção de geometrias complexas; e (iii) acessibilidade -preço razoável de máquinas e materiais (Song et al, 2016).…”

A Novel Hierarchical Security Solution for Controller-Area-Network-Based 3D Printing in a Post-Quantum World

“…Furthermore, attacks on 3D printing files and networks have been demonstrated which capture/steal model information and inject subtle, malicious changes to the data to cause printer malfunctions or product failures [ 27 , 28 , 29 ]. Other attacks focus on using machine learning and other methods to reconstruct GCode by gathering sensor data and monitoring the physical properties of the printer [ 30 ]. Lastly, the CAN bus has previously been exploited in commercial 3D printers to modify target values and feedback loops through replay attacks and impersonation.…”
