Echo On A Chip Secure Embedded Systems In Cryptography

Based on the historical development of so-called Crypto Chips, the current Transformation of Cryptography shows numerous changes, innovations and new process designs in the field of Cryptography, which also need to be integrated in a hardware design of Microprocessors and Microcontrollers for a Secure Embedded System. Using the example of the encrypting Echo protocol, a design of a hardware architecture based on three Chips is presented: The central Echo Chip #1 represents a "Trusted Execution Environment" (TEE), which is not connected to the Internet for the conversion processes from plain text to cipher text and is supposed to remain quasi original, to prevent software injections or possible uploads of copies of the plain text. The technical specifications of all three microprocessors are described in detail. The established paradigm of separation is recognized as a security feature and discussed as a perception for a Next Generation of Microcontrollers in the field of Mobile Messaging under the technical term "Going the Extra Mile". This security architecture is then discussed in the context of seven different current risk cases with the consolidated result that the well-known OSI (Open Systems Interconnection) Model is expanded to the Secure Architecture Model, abbreviated SAM.

Although security is prevalent in PCs, wireless communications and other systems today, it is expected to become increasingly important and widespread in many embedded devices. For some time, typical embedded system designers have been dealing with tremendous challenges in performance, power, price and reliability. However now they must additionally deal with definition of security requirements, security design and implementation. Given the limited number of security engineers in the market, large background of cryptography with which these standards are based upon, and difficulty of ensuring the implementation will also be secure from attacks, security design remains a challenge. This book provides the foundations for understanding embedded security design, outlining various aspects of security in devices ranging from typical wireless devices such as PDAs through to contactless smartcards to satellites.

This textbook provides an all-in-one approach for learning about hardware security of cryptographic systems. It gives the necessary background on mathematics that is used for the construction of symmetric and public-key cryptosystems. Then, it introduces the most commonly used encryption algorithms that can be found on a wide variety of embedded devices to provide confidentiality, integrity, and authenticity of the messages/data. Finally, it provides theoretical and practical details on the two most common attack methods in hardware security – side-channel attacks, and fault injection attacks, together with the protection methods used against both.

The great strides made over the past decade in the complexity and network functionality of embedded systems have significantly enhanced their attractiveness for use in critical applications such as medical devices and military communications. However, this expansion into critical areas has presented embedded engineers with a serious new problem: their designs are now being targeted by the same malicious attackers whose predations have plagued traditional systems for years. Rising concerns about data security in embedded devices are leading engineers to pay more attention to security assurance in their designs than ever before. This is particularly challenging due to embedded devices’ inherent resource constraints such as limited power and memory. Therefore, traditional security solutions must be customized to fit their profile, and entirely new security concepts must be explored. However, there are few resources available to help engineers understand how to implement security measures within the unique embedded context. This new book from embedded security expert Timothy Stapko is the first to provide engineers with a comprehensive guide to this pivotal topic. From a brief review of basic security concepts, through clear explanations of complex issues such as choosing the best cryptographic algorithms for embedded utilization, the reader is provided with all the information needed to successfully produce safe, secure embedded devices. The ONLY book dedicated to a comprehensive coverage of embedded security! Covers both hardware- and software-based embedded security solutions for preventing and dealing with attacks Application case studies support practical explanations of all key topics, including network protocols, wireless and cellular communications, languages (Java and C/++), compilers, web-based interfaces, cryptography, and an entire section on SSL

On any advanced integrated circuit or "system-on-chip" there is a need for security. In many applications the actual implementation has become the weakest link in security rather than the algorithms or protocols. The purpose of the book is to give the integrated circuits and systems designer an insight into the basics of security and cryptography from the implementation point of view. As a designer of integrated circuits and systems it is important to know both the state-of-the-art attacks as well as the countermeasures. Optimizing for security is different from optimizations for speed, area, or power consumption. It is therefore difficult to attain the delicate balance between the extra cost of security measures and the added benefits.
