HKG18-402 - Build secure key management services in OP-TEE

Session ID: HKG18-402 Session Name: HKG18-402 - Build secure key management services in OP-TEE Speaker: Etienne Carriere Track: Security ★ Session Summary ★ The session presents an initiative to build secure key management services in the OP-TEE project. Based on OP-TEE services (persistent storage, cryptography, time, etc) one could build a trusted application of store and use secure keys. An open source implementation for generic key services could be of interest. However there are many client APIs defined in the ecosystem which is a matter of concern for standardization of such services. The session will open a discussion on this and presents the current choice of the PKCS#11 Cryptoki. There can be lot of key attributes and cryptographic schemes to be supported. The session will present the current plans (starting from AES flavors) and what is currently missing in the OP-TEE (as certificate support, bootloader support). This session aims at getting feedback from the community on this topic, discuss about expected services and client APIs. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-402/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-402.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-402.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Security 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961

Demystifying Security Root of Trust Approaches for IoT/Embedded - SFO17-304

Session ID: SFO17-304 Session Name: Demystifying Security Root of Trust Approaches for IoT/Embedded - SFO17-304 Speaker: Suresh Marisetty Track: LHG,LITE,Security ★ Session Summary ★ The current trend of IoT market segment is expected to enable and deploy about 50 billion connected devices by year 2020. IoT devices will be deployed across the board to cater to multiple use cases like Home/building Automation, Automotive, a highly fragmented embedded segment: gateways, set top boxes, security cameras, industrial automation, digital signage, healthcare, etc. This trend will bring about a great challenge of securing the connected end point IoT devices from a myriad of physical and remote attacks ex: DDOS Mirai botnet launched through IoT devices like digital cameras and DVR players Problem Statement: Each use cases has its own IoT device constraints like: Cost, Power, Performance, memory footprint, security objectives, etc. The fundamental basis for any secure IoT and Embedded solution is the Root of Trust (RoT), which provides assurance of the integrity of the system software from: boot and runtime firmware, to OS loader, to the Kernel, to the user Applications. This poses a serious issue and challenges the one-size fits all RoT solution model. ARM has taken on this challenge head on to come up with a microcontroller security architecture solution that caters to the various IoT devices constraints, by offering ARM Cortex-M family of processors. ARM’s flexible and scalable architecture solution will allow an OEM or Silicon partner to adapt the base security architecture and to extend it in a seamless way. This caters to the requirements of different market segments through add-on hardware, firmware and software security enhancements. The session will present the ARM’s base security system and software architecture based on the upcoming Cortex V8M solution that will provide a hardware and firmware assisted Trust Zone based Security RoT aka TBSA-M for a range of markets, to include the highly constrained IoT devices. Furthermore, the session will discuss about how the base RoT capability can be extended in a seamless way with additional hardware assisted mechanisms to offer high levels of functionality and/or robustness for less constrained IoT devises with options like TBSA-M+, TBSA-HSM and platform level security software abstraction framework to decouple the chosen RoT capability for various OSes and the Cloud security frameworks. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/sfo17/sfo17-304/ Presentation: Video: https://www.youtube.com/watch?v=aIwmRXFOshs --------------------------------------------------- ★ Event Details ★ Linaro Connect San Francisco 2017 (SFO17) 25-29 September 2017 Hyatt Regency San Francisco Airport

LAS16-111: Easing Access to ARM TrustZone – OP-TEE and Raspberry Pi 3

LAS16-111: Raspberry Pi3, OP-TEE and JTAG debugging Speakers: Date: September 26, 2016 ★ Session Description ★ ARM TrustZone is a critical technology for securing IoT devices and systems. But awareness of TrustZone and its benefits lags within the maker community as well as among enterprises. The first step to solving this problem is lowering the cost of access. Sequitur Labs and Linaro have joined forces to address this problem by making a port of OP-TEE available on the Raspberry Pi 3. The presentation covers the value of TrustZone for securing IoT and how customers can learn more through this joint effort. Embedded systems security remains a challenge for many developers. Awareness of mature, proven technologies such as ARM TrustZone is very low among the Maker community as well as among enterprises. As a result this foundational technology is largely being ignored as a security solution. Sequitur Labs and Linaro have taken an innovative approach combining an Open Source solution – OP-TEE with Raspberry Pi 3. The Raspberry Pi 3 is one of the world’s most popular platforms among device makers. Its value as an educational tool for learning about embedded systems development is proven. Sequitur Labs have also enabled bare metal debugging via JTag on the Pi 3 enhancing the value of the Pi 3 as an educational tool for embedded systems development. The presentation will focus on ARM v8a architecture and instruction set ARM Trusted Firmware TrustZone and OP-TEE basics JTAG and bare metal debugging the Raspberry Pi 3 ★ Resources ★ Etherpad: pad.linaro.org/p/las16-111 Presentations & Videos: http://connect.linaro.org/resource/las16/las16-111/ ★ Event Details ★ Linaro Connect Las Vegas 2016 – #LAS16 September 26-30, 2016 http://www.linaro.org http://connect.linaro.org

LAS16-TR04: Using tracing to tune and optimize EAS (English) Speakers: Leo Yan Date: September 28, 2016 ★ Session Description ★ The Energy Aware Scheduler relies on a power model, rather than on heuristics, to make decisions and reduce power usage. As a result of this fact-based decision making EAS presents very few tunables and thus requires a significantly different approach to tuning and optimization when compared to the traditional tune/benchmark/repeat cycle. Tuning EAS has perhaps more similar to debugging: using trace tools such as ftrace, kernelshark and LISA, we can examine its decision making and look for ways to improve this decision making. This talk will offer a practical introduction to using these trace tools. ★ Resources ★ Etherpad: pad.linaro.org/p/las16-tr04 Presentations & Videos: http://connect.linaro.org/resource/las16/las16-tr04/ ★ Event Details ★ Linaro Connect Las Vegas 2016 – #LAS16 September 26-30, 2016 http://www.linaro.org http://connect.linaro.org

LAS16-500: The Rise and Fall of Assembler and the VGIC from Hell

n|u - The Open Security Community

LAS16-500: The Rise and Fall of Assembler and the VGIC from Hell Speakers: Marc Zyngier, Christoffer Dall Date: September 30, 2016 ★ Session Description ★ KVM/ARM has grown up. While the initial implementation of virtualization support for ARM processors in Linux was a quality upstream software project, there were initial design decisions simply not suitable for a long-term maintained hypervisor code base. For example, the way KVM/ARM utilized the hardware support for virtualization, was by running a ‘switching’ layer of code in EL2, purely written in assembly. This was a reasonable design decision in the initial implementation, as the switching layer only had to do one thing: Switch between a VM and the host. But as we began to optimize the implementation, add support for ARMv8.1 and VHE, and added features such as debugging support, we had to move to a more integrated approach, writing the switching logic in C code as well. As another example, the support for virtual interrupts, famously known as the VGIC, was designed with a focus on optimizing MMIO operations. As it turns out, MMIO operations is a less important and infrequent operation on the GIC, and the design had some serious negative consequences for supporting other state transitions for virtual interrupts and had negative performance implications. Therefore, we completely redesigned the VGIC support, and implemented the whole thing from scratch as a team effort, with a very promising result, upstream since Linux v4.7. In this talk we will cover the evolution of this software project and give an overview of the state of the project as it is today. ★ Resources ★ Etherpad: pad.linaro.org/p/las16-500 Presentations & Videos: http://connect.linaro.org/resource/las16/las16-500/ ★ Event Details ★ Linaro Connect Las Vegas 2016 – #LAS16 September 26-30, 2016 http://www.linaro.org http://connect.linaro.org

Deep Learning Neural Network Acceleration at the Edge - Andrea Gallo

Short The growing amount of data captured by sensors and the real time constraints imply that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in Arm-based platforms provide an unprecedented opportunity for new intelligent devices. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators. Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, accelerator solutions, and will describe the efforts underway in the Arm ecosystem. Abstract The dramatically growing amount of data captured by sensors and the ever more stringent requirements for latency and real time constraints are paving the way for edge computing, and this implies that not only big data analytics but also Machine Learning (ML) inference shall be executed at the edge. The multiple options for neural network acceleration in recent Arm-based platforms provides an unprecedented opportunity for new intelligent devices with ML inference. It also raises the risk of fragmentation and duplication of efforts when multiple frameworks shall support multiple accelerators. Andrea Gallo, Linaro VP of Segment Groups, will summarise the existing NN frameworks, model description formats, accelerator solutions, low cost development boards and will describe the efforts underway to identify the best technologies to improve the consolidation and enable the competitive innovative advantage from all vendors. Audience The session will be useful for executives to engineers. Executives will gain a deeper understanding of the issues and opportunities. Engineers at NN acceleration IP design houses will take away ideas for how to collaborate in the open source community on their area of expertise, how to evaluate the performance and accelerate multiple NN frameworks without modifying them for each new IP, whether it be targeting edge computing gateways, smart devices or simple microcontrollers. Benefits to the Ecosystem The AI deep learning neural network ecosystem is starting just now and it has similar implications with open source as GPU and video accelerators had in the early days with user space drivers, binary blobs, proprietary APIs and all possible ways to protect their IPs. The session will outline a proposal for a collaborative ecosystem effort to create a common framework to manage multiple NN accelerators while at the same time avoiding to modify deep learning frameworks with multiple forks.

Bud17 113: distribution ci using qemu and open qa

“Delivering a well working distribution is hard. There are a lot of different hardware platforms that need to be verified and the software stack is in a big flux during development phases. In rolling releases, this gets even worse, as nothing ever stands still. The only sane answer to that problem are working Continuous Integration tests. The SUSE way to check whether any change breaks normal distribution behavior is OpenQA. Using OpenQA we can automatically run tests that hard working QA people did manually in the old days. That way we have fast enough turnaround times to find and reject breaking changes This session shows how OpenQA works, what pitfalls we had to make ARM work with OpenQA and what we’re doing to improve it for ARM specific use cases.”

HKG18-TR08 - Upstreaming SVE in QEMU

"Session ID: HKG18-TR08 Session Name: HKG18-TR08 - Upstreaming SVE in QEMU Speaker: Alex Bennée,Richard Henderson Track: Enterprise ★ Session Summary ★ ARM's Scalable Vector Extensions is an innovative solution to processing highly data parallel workloads. While several out-of-tree attempts at implementing SVE support for QEMU existed, we took a fundamentally different approach to solving key challenges and therefore pursued a from-scratch QEMU SVE implementation in Linaro. Our strategic choice was driven by several factors. First as an ""upstream first"" organisation we were focused on a solution that would be readily accepted by the upstream project. This entailed doing our development in the open on the project mailing lists where early feedback and community consensus can be reached. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-tr08/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-tr08.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-tr08.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Enterprise 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961"

HKG18-120 - Devicetree Schema Documentation and Validation

"Session ID: HKG18-120 Session Name: HKG18-120 - Structured Documentation and Validation for Device Tree Speaker: Grant Likely Track: Kernel ★ Session Summary ★ Devicetree has become the dominant hardware configuration language used when building embedded systems. Projects using Devicetree now include Linux, U-Boot, Android, FreeBSD, and Zephyr. However, it is notoriously difficult to write correct Devicetree data files. The dtc tools perform limited tests for valid data, and there there is not yet a way to add validity test for specific hardware descriptions. Neither is there a good way to document requirements for specific bindings. Work is underway to solve these problems. This session will present a proposal for adding Devicetree schema files to the Devicetree toolchain that can be used to both validate data and produce usable documentation. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-120/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-120.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-120.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Kernel 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961"

HKG18-223 - Trusted FirmwareM: Trusted boot

"Session ID: HKG18-223 Session Name: HKG18-223 - Trusted Firmware M : Trusted Boot Speaker: Tamas Ban Track: LITE ★ Session Summary ★ An overview of the trusted boot concept and firmware update on the ARMv8-M based platform and how MCUBoot acts as a BL2 bootloader for TF-M. Trusted Firmware M In October 2017, Arm announced the vision of Platform Security Architecture (PSA) - a common framework to allow everyone in the IoT ecosystem to move forward with stronger, scalable security and greater confidence. There are three key stages to the Platform Security Architecture: Analysis, Architecture and Implementation which are described at https://developer.arm.com/products/architecture/platform-security-architecture. _Trusted Firmware M, i.e. TF-M, is the Arm project to provide an open source reference implementation firmware that will conform to the PSA specification for M-Class devices. Early access to TF-M was released in December 2017 and it is being made public during Linaro Connect. The implementation should be considered a prototype until the PSA specifications reach release state and the code aligns._ --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-223/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-223.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-223.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: LITE 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961"

Session ID: HKG18-500K1 Session Name: HKG18-500K1 - Keynote: Dileep Bhandarkar - Emerging Computing Trends in the Datacenter Speaker: Not Available Track: Keynote ★ Session Summary ★ For decades we have been able to take advantage of Moore’s Law to improve single thread performance, reduce power and cost with each generation of semiconductor technology. While technology has advanced after the end of Dennard scaling more than 10 years ago, the advances have slowed down. Server performance increases have relied on increasing core counts and power budgets. At the same time, workloads have changed in the era of cloud computing. Scale out is becoming more important than scale up. Domain specific architectures have started to emerge to improve the energy efficiency of emerging workloads like deep learning This talk will provide a historical perspective and discuss emerging trends driving the development of modern servers processors. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-500k1/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-500k1.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-500k1.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Keynote 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
