The classic guide to cryptography and network security – now fully updated! “Alice and Bob are back!” Widely regarded as the most comprehensive yet comprehensible guide to network security and cryptography, the previous editions of Network Security received critical acclaim for lucid and witty explanations of the inner workings of cryptography and network security protocols. In this edition, the authors have significantly updated and revised the previous content, and added new topics that have become important. This book explains sophisticated concepts in a friendly and intuitive manner. For protocol standards, it explains the various constraints and committee decisions that led to the current designs. For cryptographic algorithms, it explains the intuition behind the designs, as well as the types of attacks the algorithms are designed to avoid. It explains implementation techniques that can cause vulnerabilities even if the cryptography itself is sound. Homework problems deepen your understanding of concepts and technologies, and an updated glossary demystifies the field's jargon. Network Security, Third Edition will appeal to a wide range of professionals, from those who design and evaluate security systems to system administrators and programmers who want a better understanding of this important field. It can also be used as a textbook at the graduate or advanced undergraduate level. Coverage includes Network security protocol and cryptography basics Design considerations and techniques for secret key and hash algorithms (AES, DES, SHA-1, SHA-2, SHA-3) First-generation public key algorithms (RSA, Diffie-Hellman, ECC) How quantum computers work, and why they threaten the first-generation public key algorithms Quantum-safe public key algorithms: how they are constructed, and optimizations to make them practical Multi-factor authentication of people Real-time communication (SSL/TLS, SSH, IPsec) New applications (electronic money, blockchains) New cryptographic techniques (homomorphic encryption, secure multiparty computation)

It has become glaringly clear that any communicative act online is subject to breach by intelligence agencies, cybercriminals, advertising networks, employers, and corporate data miners, to mention the most obvious intruders. Internet users, seeing no other choice than to hop onto the web-based bandwagon, have come to depend on a networked communications environment that is fundamentally insecure. Now lawmakers worldwide are gearing up to intervene. Arguing for a stricter stance on protecting private communications security, this groundbreaking study offers a conceptual and legislative toolkit leading to a step-by-step regulatory model in EU law. The proposed model is tested in two detailed case studies on HTTPS and cloud communications. From the interlocking perspectives of fundamental rights, systems design, and political organization, the regulatory model proposed is tested on HTTPS, which covers the user-provider relationship in web browsing, and on "cloud" communications that affect interdomain and intradomain communications. The case studies are based on the infamous DigiNotar breach and the MUSCULAR programme disclosed by whistle-blower Edward Snowden and contain original legal, security economics, and computer science research, conducted jointly with scholars trained in these disciplines. Responding to a general positive human right to communications security that is emerging from European fundamental rights law, this book not only provides one of the first interdisciplinary studies to appear in the academic literature on EU communications security law, but also offers broad recommendations to the EU lawmaker and gives directions for future research. It is sure to become a first point of discussion, reference, and legislative action for policymakers and practitioners in Europe and beyond.

2009 CHOICE AWARD OUTSTANDING ACADEMIC TITLE Information and communications security is a hot topic in private industry as well as in government agencies. This book provides a complete conceptual treatment of securing information and transporting it over a secure network in a manner that does not require a strong mathematical background. It stresses why information security is important, what is being done about it, how it applies to networks, and an overview of its key issues. It is written for anyone who needs to understand these important topics at a conceptual rather than a technical level.

Communications represent a strategic sector for privacy protection and for personal, company, national and international security. The interception, damage or lost of information during communication can generate material and non material economic damages from both a personal and collective point of view. The purpose of this book is to give the reader information relating to all aspects of communications security, beginning at the base ideas and building to reach the most advanced and updated concepts. The book will be of interest to integrated system designers, telecommunication designers, system engineers, system analysts, security managers, technicians, intelligence personnel, security personnel, police, army, private investigators, scientists, graduate and postgraduate students and anyone that needs to communicate in a secure way.

If you need to know more about communication's security management, this is the perfect book for you......... Secure Communications confronts the practicalities of implementing the ideals of the security policy makers. Based on 15 years experience, the author addresses the key problems faced by security managers, starting from network conception, initial setting up and the maintenance of network security by key management. Many different types of communications networks are discussed using a wide range of topics, including voice, telephone, mobile phone, radio, fax, data transmission and storage, IP, and Email technologies. Each topic is portrayed in a number of different operational environments. * Explains the practical links between cryptography and telecommunications * Addresses the pertinent issues of implementation of cryptography as a method of protecting information * Supports each communications technology and the fundamentals of cryptography with useful and relevant telecommunications material * Provides practical solutions by network modelling and stimulating the reader's imagination on how to deal with their own network protection * Highlights the need for a structured infrastructure in an organisation's security that complements the technical solutions Easy to read and highly illustrated, this timely publication probes the sensitive issues that manufacturers and agencies prefer to avoid and uses eye opening, historical events, to highlight the failings and weaknesses of the past and present.
