Dead Printers Tell No Tales

What this episode covers

Philip Tricca, a security engineer at Oxide Computer Company, explains the critical process of establishing a Root of Trust (RoT) and Public Key Infrastructure (PKI) for their hardware products. He details the 'key ceremony' required to generate and store secrets securely, highlighting the initial use of a dot matrix printer for printing key shares and the subsequent discovery that tamper-evident packaging was being used incorrectly. The team had to repeat the ceremony to ensure the integrity of the key distribution, which is stored in a bank vault, to prevent spoofing and ensure customer trust before shipping their first rack-scale computers.

    PKI and IoT Device Security in 2021 | Keyfactor's Ellen Boehm

    Ellen Boehm, Senior Director of IoT Product Management at KeyFactor, discusses the evolution of IoT device security and the critical role of Public Key Infrastructure (PKI). She explains how asymmetric cryptography and unique digital identities protect devices from tampering and counterfeiting, particularly in manufacturing and supply chain contexts. Boehm highlights the shift toward edge computing and AI, emphasizing that trust must be established before any data processing occurs. She advises manufacturers to implement code signing, secure boot, and long-term certificate management strategies to comply with emerging regulations in medical, automotive, and industrial sectors.

    Ep048: Truly Trustworthy Hardware, Glowing Uranium Marbles, Bitstreaming the USB, Chaos of Congress

    Hackaday editors Mike Szczys and Elliot Williams review the week's most interesting hardware hacks, starting with Elliot's experience at the Chaos Communications Congress (36c3), where he showcased a hoverboard-derived electric cargo carrier and discussed various community projects. The hosts then cover a diverse range of builds, including a verifiable hardware platform called 'Be Trusted' designed to prevent tampering, a uranium marble-based random number generator, and a VGA-to-USB adapter reverse-engineered for bitstreaming. They also highlight creative uses of 3D printing for paper pulp molds, a discrete 1-kilopixel camera, and the democratization of FPGAs and AI on the edge.

    451: From Concept to Launch

    Elecia White, founder of Logical Elegance, and panelists Phillip Johnston of Embedded Artistry and Tyler Hoffman of Memfault discuss the software tasks often overlooked during the transition from concept to manufacturing launch. They emphasize the necessity of robust bootloaders, OTA update mechanisms, and dedicated manufacturing firmware that operates offline. The group highlights specific failures such as bricked inventory due to faulty OTA, network congestion in factories, and the high cost of testing security features like self-bricking. They also cover the importance of per-device key management, deterministic testing environments, and integrating manufacturing validation into CI pipelines.

    028 - Everyone Has a Bag of Tricks

    Johnny Xmas (@J0hnnyXm4s), a security architect and reverse engineer, discusses his career path from pharmacy to infosec and details the community effort to reverse engineer TSA master keys. He explains how the keys were leaked via a vendor catalog and Instagram, and how the community used 3D printing and lock disassembly to create working copies, highlighting the security implications for luggage and encryption. Xmas also describes his work at Kasada, a company that defends web infrastructure against automated abuse by detecting client-side automation rather than relying on traditional Web Application Firewalls (WAFs).

    IoT Security & The Importance Certificates with Ellen Boehm, SVP, IoT at Keyfactor

    Ellen Boehm, SVP of IoT at Keyfactor, discusses the critical role of digital certificates and public key infrastructure (PKI) in securing IoT devices, particularly in high-stakes industries like medical and automotive. She explains how Keyfactor helps OEMs manage certificate lifecycles at scale to prevent field failures and prepare for post-quantum cryptography threats. The conversation also covers the challenges of integrating enterprise security solutions with open-source foundations and the emerging need for OT security in industrial automation.
