Secure Boot Revisited [chapter]

Steffen Sanwald, Liron Kaneti, Marc Stöttinger, Martin Böhner
2019
This paper investigates the major causes for security weaknesses of secure boot implementations.  ...  The paper provides recommendations to increase the understanding of implementing secure boot securely on both sides and derives a set of reference requirements as starting point for secure boot ECU requirements  ...  However, encrypting content Secure Boot Revisited does not ensure its integrity and authenticity.  ...

Reflections on trusting trust revisited

Diomidis Spinellis
2003 Communications of the ACM  
The recent attack modifies the saved data of a particular game in a way that renders the trusted game into an untrusted agent that can then be used to boot Linux.  ...  "Trusted Computing" (TC) platforms include specialized hardware or a processor that can monitor a system's boot process to ensure the computer is based on appropriately certified hardware and software.  ...

D4.2 - Remote attestation of workloads in ITEEs

RISE Research Institutes Of Sweden AB, UBITECH, SECURA BV
2020 Zenodo  
Some important components in trusted computing are • Secure boot: boot into a well-defined and trusted configuration • Strong memory isolation: provide memory isolated from other components and interfaces  ...  We will revisit this subject in Section 3.2. Attestation We have briefly looked into how attestation in TPM works. In the following we will revisit attestation, this time as a generic operation.  ...  As an example, the TPM trusted boot is a layered attester with the layers being components of the boot sequence (firmware, bootloader, OS, …).  ...

Chrome book Firmware Internals [chapter]

Jiming Sun, Marc Jones, Stefan Reinauer, Vincent Zimmer
2015 Embedded Firmware Solutions  
You should revisit the previous chapter for specific information about the internals of coreboot.  ...  Chrome OS devices use the Google verified boot security library for the chain of trust, which starts in write-protected coreboot romstage.  ...  The EC boots its RO firmware and powers on the AP. 2. The AP boots its RO firmware. 3. The AP verifies its RW firmware and jumps to it. 4. The EC computes a hash of its RW firmware. 5.  ...

Implementing Trust in Cloud Infrastructures

Ricardo Neisse, Dominik Holling, Alexander Pretschner
2011 2011 11th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing  
We evaluate both security and performance of this system.  ...  Building on the analysis of several relevant attack scenarios, our system is implemented on top of the Xen Cloud Platform and makes use of trusted computing technology to provide security guarantees.  ...  EXAMPLE REVISITED To illustrate how BonaFides helps secure a cloud infrastructure, we revisit the example described in §I where a service provider S runs its service on the hardware of an infrastructure  ...

Security architectures revisited

Hermann Härtig
2002 Proceedings of the 10th workshop on ACM SIGOPS European workshop: beyond the PC - EW10  
These include small interface technologies, access-control contracts, tunneling, secure booting, effective resource control, and virtual machines.  ...  The knowledge in technologies needed to build secure platforms, or Security Architectures, has significantly matured over the recent years.  ...  It does not address secure booting techniques to prevent that kind of attacks.  ...

Boot Attestation: Secure Remote Reporting with Off-The-Shelf IoT Sensors [chapter]

Steffen Schulz, André Schaller, Florian Kohnhäuser, Stefan Katzenbeisser
2017 Lecture Notes in Computer Science  
In Boot Attestation, software integrity measurements are immediately committed to during boot, thus relaxing the traditional requirement for secure storage and reporting.  ...  require custom secure hardware extensions that are difficult to adopt across IoT vendors.  ...  We will revisit this property when implementing our Root of Trust (RoT) in Section 6.  ...

John Darling, a New York Munchausen

Lt. Herbert Halpert
1944 Journal of American Folklore  
I first heard of John Darling and other local folk heroes on these trips, but made little effort to secure more than a few of the tales told.  ...  Thompson had published seven of John Darling’s stories in his book, Body, Boots & Britches (Philadelphia, 1940, 131-5), and presented some evidence that Darling had once actually lived in Sullivan County  ...

Multi-layer Attestation for Internet of Things using Blockchain

2020 International Journal of Engineering and Advanced Technology  
Sine all such security primitives are either architecture or manufacturer specific it is not possible to build common unified attestation scheme for all constituent IoT devices in a typical IoT network  ...  PROBLEM STATEMENT In the light of above-mentioned multiple research trends for IoT attestation authors attempt to revisit definition of what needs to secured or attested as first step and subsequently  ...  measures like session based key for securing exchanges.  ...
