دانلود کتاب امنیت سیستماتیک -ایجاد امنیت کوانتومی

I was watching a comedy skit by Nate Bargatze, a popular comedian, where he joked about being the worst time traveler imaginable. His punchline was that if he ever traveled back in time, he wouldn’t be able to prove he was from the future because he has no clue how anything actually works. His delivery was great, and the reality is that nowadays most people can’t explain how a lot of the things that we take for granted in our lives operate. Take engineering as an example, there was a time when engineering mainly referred to civil and mechanical. We had urban planning, sanitation systems, and bridges that formed the basis of the field. Later machine tools, steam engines, railways, and ships took form driving both static and dynamic engineering principles. As our societies became more complex and our understanding of the world around us grew, electrical and electronic engineering took form; chemical engineering split off; and as we went further, aeronautical and aerospace engineering took on distinct identities of their own. As we look to today and beyond, we have biomedical engineering, robotics, and quantum engineering that continue to take the concept of engineering and further specialize due to the growing body of knowledge that is accumulating over time. Where once you had geniuses who dabbled in all aspects of engineering, as far back as Imhotep in Egypt to Archimedes in Greece, Vitruvius in Rome, Al-Jazari, who designed advanced water clocks, and let’s not forget Leonardo Da Vinci; today, one person cannot know all aspects of our engineering knowledge base. You think about it, and many of us would agree with Nate that it would be difficult for us to explain how our modern-day world works because it’s become so specialized and complex. The basis of this book is information security and how it is impacted by the emergence of quantum computing. My approach in presenting a systematic process for building quantum security is to establish a basis of understanding of what quantum computing really is. This means we need to step back and understand where quantum computing comes from and the history of our progression to this point, where we get to talk about neat things like qubits, quantum gates, and all the craziness associated with the observer’s impact on aspects of the world around us. Our goal is to understand how we build quantum security practices while paying homage to the giants of the past who established the basis for the practical application of a physics that to this day carries with it an uneasy acceptance by our best minds. In writing this book, I certified for myself that the principles of physics are essential for us to understand what building quantum security really means. I wrote the book and then came back around two more times to read it after going through the research and gaining insights on where we need to get to in order to understand a new era of computing. What I found and confirmed was that our vernacular is changing. The language and terms we use as we head into the next decade will require us to understand some essential physics in order to accurately capture the emergence of quantum security. I try not to waste time in my pursuit to deliver concepts, and it was important for me to test the construction of this book to ensure nothing is wasted and nothing is optional. I can tell you this: through the eight-month journey of research and contemplation, I found that we, as security professionals and folks from other industries and specialties, must understand some basic physics principles to understand where we are headed and how we can take advantage of this space. In our journey together, we will address some concepts that are intended to lead us to the end game; impact on security, but along the way, our exploration might reveal some insights on how the world turns and maybe, just maybe, we might understand a few things about our reality so that if we ever find ourselves traveling to the past through a spontaneous anomaly in the spacetime fabric, that we can articulate within reason, some of the things that offer evidence that we are from the future. Now don’t worry; we’re not going to go into deriving anything or spending any significant time on formulas and equations (maybe a few though), but we will conceptualize our path to where we are so that we gain an appreciation for exactly why things like cryptography and encryption are under attack by quantum algorithms. I am a security professional who likes to understand the “reasons why” from a holistic perspective. I stand behind the notion that if we don’t know the basis of superposition in quantum computing, then how are we supposed to understand the nature of its impact in our security space? If the buzzword of the decade, entanglement, coupled with interference is something that conceptually we cannot understand (albeit the best minds debate this as well), then we can’t possibly understand the natural science around its effect on the world we know. In its truest form, the essence of being “systematic” to me means we address the topic not just in a rational order but in a completeness that gives us a solid three-sixty foundation.
