Trusted execution environments (TEEs) protect sensitive code and data on computing platforms, even when the primary operating system is compromised. Once a technical curiosity, TEEs have rapidly become a key component in securing numerous systems from cloud servers to constrained devices. Today, TEEs have been deployed on billions of devices for protecting financial payments, personal files, copyrighted media content, and many others. Despite this, TEEs remain poorly understood due to their complexity and diversity. This book addresses this gap, providing a comprehensive treatment of different TEE technologies, their features, benefits, and shortcomings. A holistic view of secure and trusted execution is taken, examining smart cards and CPU protection rings before discussing modern TEEs, such as Intel SGX and ARM TrustZone. A wide range of paradigms for building secure and trusted execution environments are explored, from dedicated security chips to system-on-chip extensions and virtualisation technologies. The relevant industry standards and specifications are covered in detail, including how TEEs are evaluated and certified in practice with respect to security. Several case studies are presented showing how TEEs are used in some common security mechanisms, such as secure boot sequences, biometric authentication, and file-based encryption. This book also discusses present challenges in the field, covering potential attack vectors against TEEs and concerns relating to fragmentation, interoperability, and transparency. Lastly, a selection of future directions are examined that may be used by the trusted execution environments of tomorrow. This book is particularly targeted at practitioners and researchers in cyber security, such as penetration testers, security engineers, and security analysts. Additionally, this book serves as a valuable resource for university students, both postgraduate and advanced undergraduates, and professors in computer science and electrical engineering.

"This book is a must have resource guide for anyone who wants to ... implement TXT within their environments. I wish we had this guide when our engineering teams were implementing TXT on our solution platforms!” John McAuley,EMC Corporation "This book details innovative technology that provides significant benefit to both the cloud consumer and the cloud provider when working to meet the ever increasing requirements of trust and control in the cloud.” Alex Rodriguez, Expedient Data Centers "This book is an invaluable reference for understanding enhanced server security, and how to deploy and leverage computing environment trust to reduce supply chain risk.” Pete Nicoletti. Virtustream Inc. Intel® Trusted Execution Technology (Intel TXT) is a new security technology that started appearing on Intel server platforms in 2010. This book explains Intel Trusted Execution Technology for Servers, its purpose, application, advantages, and limitations. This book guides the server administrator / datacenter manager in enabling the technology as well as establishing a launch control policy that he can use to customize the server’s boot process to fit the datacenter’s requirements. This book explains how the OS (typically a Virtual Machine Monitor or Hypervisor) and supporting software can build on the secure facilities afforded by Intel TXT to provide additional security features and functions. It provides examples how the datacenter can create and use trusted pools. With a foreword from Albert Caballero, the CTO at Trapezoid.

With growing interest in computer security and the protection of the code and data which execute on commodity computers, the amount of hardware security features in today's processors has increased significantly over the recent years. No longer of just academic interest, security features inside processors have been embraced by industry as well, with a number of commercial secure processor architectures available today. This book aims to give readers insights into the principles behind the design of academic and commercial secure processor architectures. Secure processor architecture research is concerned with exploring and designing hardware features inside computer processors, features which can help protect confidentiality and integrity of the code and data executing on the processor. Unlike traditional processor architecture research that focuses on performance, efficiency, and energy as the first-order design objectives, secure processor architecture design has security as the first-order design objective (while still keeping the others as important design aspects that need to be considered). This book aims to present the different challenges of secure processor architecture design to graduate students interested in research on architecture and hardware security and computer architects working in industry interested in adding security features to their designs. It aims to educate readers about how the different challenges have been solved in the past and what are the best practices, i.e., the principles, for design of new secure processor architectures. Based on the careful review of past work by many computer architects and security researchers, readers also will come to know the five basic principles needed for secure processor architecture design. The book also presents existing research challenges and potential new research directions. Finally, this book presents numerous design suggestions, as well as discusses pitfalls and fallacies that designers should avoid.

Recently, mobile security has garnered considerable interest in both the research community and industry due to the popularity of smartphones. The current smartphone platforms are open systems that allow application development, also for malicious parties. To protect the mobile device, its user, and other mobile ecosystem stakeholders such as network operators, application execution is controlled by a platform security architecture. This book explores how such mobile platform security architectures work. We present a generic model for mobile platform security architectures: the model illustrates commonly used security mechanisms and techniques in mobile devices and allows a systematic comparison of different platforms. We analyze several mobile platforms using the model. In addition, this book explains hardware-security mechanisms typically present in a mobile device. We also discuss enterprise security extensions for mobile platforms and survey recent research in the area of mobile platform security. The objective of this book is to provide a comprehensive overview of the current status of mobile platform security for students, researchers, and practitioners.
