Explaining the mathematics of cryptography The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptography-the science of sending secret messages. Using a wide range of historical anecdotes and real-world examples, Joshua Holden shows how mathematical principles underpin the ways that different codes and ciphers work. He focuses on both code making and code breaking and discusses most of the ancient and modern ciphers that are currently known. He begins by looking at substitution ciphers, and then discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, connections between ciphers and computer encryption, stream ciphers, public-key ciphers, and ciphers involving exponentiation. He concludes by looking at the future of ciphers and where cryptography might be headed. The Mathematics of Secrets reveals the mathematics working stealthily in the science of coded messages. A blog describing new developments and historical discoveries in cryptography related to the material in this book is accessible at http://press.princeton.edu/titles/10826.html.

SECURITY TECHNOLOGIES AND SOCIAL IMPLICATIONS Explains how the latest technologies can advance policing and security, identify threats, and defend citizens from crime and terrorism Security Technologies and Social Implications focuses on the development and application of new technologies that police and homeland security officers can leverage as a tool for both predictive and intelligence-led investigations. The book recommends the best practices for incorporation of these technologies into day-to-day activities by law enforcement agencies and counter-terrorism units. Practically, it addresses legal, technological, and organizational challenges (e.g. resource limitation and privacy concerns) combined with challenges related to the adoption of innovative technologies. In contrast to classic tools, modern policing and security requires the development and implementation of new technologies using AI, machine learning, social media tracking, drones, robots, GIS, computer vision, and more. As crime (and cybercrime in particular) becomes more and more sophisticated, security requires a complex mix of social measures, including prevention, detection, investigation, and prosecution. Key topics related to these developments and their implementations covered in Security Technologies and Social Implications include: New security technologies and how these technologies can be implemented in practice, plus associated social, ethical or policy issues Expertise and commentary from individuals developing and testing new technologies and individuals using the technologies within their everyday roles The latest advancements in commercial and professional law enforcement technologies and platforms Commentary on how technologies can advance humanity by making policing and security more efficient and keeping citizens safe Security Technologies and Social Implications serves as a comprehensive resource for defense personnel and law enforcement staff, practical security engineers, and trainee staff in security and police colleges to understand the latest security technologies, with a critical look at their uses and limitations regarding potential ethical, regulatory, or legal issues.

This book provides a template with step-by-step instructions on how to respond and recover when hackers get into your SCADA system and cause building equipment to act erratically or fail completely. When hackers shut off the water, turn off the building power, disable the sewage effluent pumps and activate the fire alarm, you have to do something quick. It is even more alarming that hackers can do all those things at the same time-even from the other side of the planet. Not every equipment failure or power outage is a cyber-physical attack. When your building is attacked, you probably won't suspect it was a hacker-until you see a pattern. The building control system (BCS) will act "squirrelly" and you will know-it really is a cyber-physical attack. Once a cyber-physical attack occurs, it can mean years of court cases, job losses, higher insurance rates, and maybe even criminal litigation. It also takes years to overcome the loss of safety credibility to your employees and the local community. Cyber-Physical Attack Recovery Procedures provides a detailed guide to taking the right steps ahead of time, and equipping your facility and employees with the training, knowledge, and tools they need and may save lives. The book contains: A one-of-a-kind action plan describing how hackers attack building equipment, the extent of damage possible, and how to respond when a cyber-physical attack occurs. Detailed descriptions of cyber-physical attacks directed against SCADA systems or building controls, as well as cyber booby traps Invaluable appendices, including: Emergency Procedures, Team Staffing and Tasking, Alternate Site Procedures, a Documentation List, Software and Hardware Inventories, Vendor Contact Lists, External Support Agreements, and much more. What you'll learn Possible ways hackers can cause building equipment to fail. How to quickly assess the threat to his facilities in real time, how to stop a cyber-physical attack. How to restore equipment operation without doing any more damage. Who This Book Is For Architects, Engineers, Building Managers, Students, Researchers and Consultants interested in cybersecurity-attacks against facilities in the real world. Also for IT professionals getting involved in cybersecurity responsibilities.

This SpringerBrief examines the technology of email privacy encryption from its origins to its theoretical and practical details. It explains the challenges in standardization, usability, and trust that interfere with the user experience for software protection. Chapters address the origins of email encryption and why email encryption is rarely used despite the myriad of its benefits -- benefits that cannot be obtained in any other way. The construction of a secure message and its entwining with public key technology are covered. Other chapters address both independent standards for secure email and how they work. The final chapters include a discussion of getting started with encrypted email and how to live with it. Written by an expert in software security and computer tools, Encrypted Email: The History and Technology of Message Privacy is designed for researchers and professionals working in email security and encryption. Advanced-level students interested in security and networks will also find the content valuable.

This book investigates tradeoff between security and usability in designing leakage resilient password systems (LRP) and introduces two practical LRP systems named Cover Pad and ShadowKey. It demonstrates that existing LRP systems are subject to both brute force attacks and statistical attacks and that these attacks cannot be effectively mitigated without sacrificing the usability of LRP systems. Quantitative analysis proves that a secure LRP system in practical settings imposes a considerable amount of cognitive workload unless certain secure channels are involved. The book introduces a secure and practical LRP system, named Cover Pad, for password entry on touch-screen mobile devices. Cover Pad leverages a temporary secure channel between a user and a touch screen which can be easily realized by placing a hand shielding gesture on the touch screen. The temporary secure channel is used to deliver a hidden message to the user for transforming each password symbol before entering it on the touch screen. A user study shows the impact of these testing conditions on the users' performance in practice. Finally, this book introduces a new LRP system named ShadowKey. Shadow Key is designed to achieve better usability for leakage resilient password entry. It leverages either a permanent secure channel, which naturally exists between a user and the display unit of certain mobile devices, or a temporary secure channel, which can be easily realized between a user and a touch screen with a hand-shielding gesture. The secure channel protects the mappings between original password symbols and associated random symbols. Unlike previous LRP system users, Shadow Key users do not need to remember anything except their passwords. Leakage Resilient Password Systems is designed for professionals working in the security industry. Advanced-level students studying computer science and electrical engineering will find this brief full of useful material.
