Willy Messerschmitt's Bf 109 is among the most famous fighter aircraft in the history of military aviation, and it was during the Spanish Civil War that it first saw combat. Using newly discovered records, the author describes the Bf 109's operational career with the Legion Condor, the German military unit that fought in Spain. The text is enhanced by many personal accounts written by the pilots who flew the Bf 109 in Spain, with descriptions of combat and other aspects of life in Spain from 1936 to 1939. All versions of the Bf 109 that served in Spain are described, accompanied by illustrations from the pilots' notes. The book is illustrated with 235 photos--most never before published--and technical drawings. Appendixes provide detailed descriptions of the fourteen Bf 109 A fighters sent to Spain, biographies of selected pilots who served there, and a copy of J/88's victory list from the estate of a former Legion fighter pilot.

This book provides detailed and practical information for practitioners to understand why they should choose certification. It covers the pros and cons, and shows how to design to comply with the specifications (FIPS-140, SP800 documents, and related international specs such as AIS31, GM/T-0005-2021, etc.). It also covers how to perform compliance testing. By the end of the book, you will know how to interact with accredited certification labs and with related industry forums (CMUF, ICMC). In short, the book covers everything you need to know to make sound designs.There is a process for FIPS-140 (Federal Information Processing Standard) certification for cryptographic products sold to the US government. And there are parallel certifications in other countries, resulting in a non-trivial and complex process. A large market of companies has grown to help companies navigate the FIPS-140 certification process. And there are accredited certification labs you must contract toget the certification.Although this was once a fairly niche topic, it is no longer so. Other industries¿banking, military, healthcare, air travel, and more¿have adopted FIPS certification for cryptographic products. The demand for these services has grown exponentially. Still, the available skills pool has not grown. Many people are working on products with zero usable information on what to do to meet these standards and achieve certification or even understand if such certification applies to their products.What You Will LearnWhat is FIPS-140? What is the SP800 standard?What is certification? What does it look like? What is it suitable for?What is NIST? What does it do?What do accredited certification labs do?What do certification consultants do?Where and when is certification required?What do FIPS-140 modules look like?What are the sub-components of FIPS-140 modules (RNGs, PUFs, crypto functions)? How does certification work for them?What are the physical primitives (RNGs, PUFs, key stores) and how do you handle the additional complexity of certifying them under FIPS?What are the compliance algorithms (AES, SP800-90 algos, SHA, ECDSA, key agreement, etc.)?How do you design for certification (BIST, startup tests, secure boundaries, test access, zeroization, etc.)?How do you get CAVP certificates (cert houses, ACVTs)?How do you get CMVP certifications (cert houses, required documents, design information, security policy, etc.)?Who This Book Is ForHardware and software engineers or managers of engineering programs that include any form of cryptographic functionality, including silicon vendors, library vendors, OS vendors, and system integrators

This book addresses Atlantic as a global translation zone, created through a myriad of crossings, physical and conceptual, and historically shaped through the reciprocal influences between different communities situated around and beyond its shores. It was originally published as a special issue of journal, Atlantic Studies.

Roman Law in Context explains how Roman law worked for those who lived by it, by viewing it in the light of the society and economy in which it operated. The book discusses three main areas of Roman law and life: the family and inheritance; property and the use of land; commercial transactions and the management of businesses. It also deals with the question of litigation and how readily the Roman citizen could assert his or her legal rights in practice. In addition it provides an introduction to using the main sources of Roman law. The book ends with an epilogue discussing the role of Roman law in medieval and modern Europe, a bibliographical essay, and a glossary of legal terms. The book involves the minimum of legal technicality and is intended to be accessible to students and teachers of Roman history as well as interested general readers.

Provide full coverage of the required practicals and build students' working scientifically skills with questions that enable them to apply their knowledge to new contexts.

The Bf 109 E "Emil" entered service in 1938. The aircraft's DB 601 engine transformed its performance, making the Messerschmitt fighter one of the most capable anywhere in the world at the time. After seeing action late in the Spanish Civil War, the Emil was Germany's premier fighter aircraft during the early years of World War II, seeing action over Poland, France and the Low Countries, Great Britain, the Balkans, and North Africa. By the time of "Operation Barbarossa" in June 1941, the Emil had been largely replaced as the Luftwaffe's main fighter aircraft by the new Bf 109 F; however, it continued in service in the fighter-bomber, reconnaissance, and fighter-training roles. The Bf 109 E was flown by all of Germany's famed early-war fighter aces, men such as Adolf Galland, Werner Mölders, Helmut Wick, Wilhelm Balthasar, Walther Oesau, and countless others.

Random Number Generators, Principles and Practices has been written for programmers, hardware engineers, and sophisticated hobbyists interested in understanding random numbers generators and gaining the tools necessary to work with random number generators with confidence and knowledge. Using an approach that employs clear diagrams and running code examples rather than excessive mathematics, random number related topics such as entropy estimation, entropy extraction, entropy sources, PRNGs, randomness testing, distribution generation, and many others are exposed and demystified. If you have ever Wondered how to test if data is really random Needed to measure the randomness of data in real time as it is generated Wondered how to get randomness into your programs Wondered whether or not a random number generator is trustworthy Wanted to be able to choose between random number generator solutions Needed to turn uniform random data into a different distribution Needed to ensure the random numbers from your computer will work for your cryptographic application Wanted to combine more than one random number generator to increase reliability or security Wanted to get random numbers in a floating point format Needed to verify that a random number generator meets the requirements of a published standard like SP800-90 or AIS 31 Needed to choose between an LCG, PCG or XorShift algorithm Then this might be the book for you.
