Biometrics in the New World takes a fresh look at biometrics and identity management within a fast-changing world. The concept of biometric identity verification is revisited, including identity intelligence, federation and the use of third party infrastructure. Furthermore, the book examines some of the fundamentals of the technology which are often overlooked. However, the dialogue extends beyond technical considerations, and explores some of the broader societal and philosophical aspects surrounding the use of biometric applications, bringing this whole area into a new focus at a time. Topics and features: Presents a brief history of the development of biometrics, and describes some of the popularly held misconceptions surrounding the technology Investigates the challenges and possibilities of biometrics across third party infrastructures and on mobile computing devices Provides guidance on biometric systems design, stressing the importance of an end-to-end approach, together with the alignment with policy and operational procedures Explores the mechanisms necessary to enable identity intelligence, including logging mechanisms, data communications and data formats Discusses such usage issues as collaboration frameworks, and messaging and data translation Examines the impact of biometric technologies on society, for better and worse, covering issues of privacy and user factors Reviews the current situation in identity management and biometric technologies, and predicts where these trends may take us in the future This accessible and thought-provoking work is an essential guide for biometric systems integrators, professional consultancies, government agencies and other consumers of biometric technology. Academics interested in biometrics will also find the book to be a source of valuable insights, as will the casual reader.

Dynamic secrets are constantly generated and updated from messages exchanged between two communication users. When dynamic secrets are used as a complement to existing secure communication systems, a stolen key or password can be quickly and automatically reverted to its secret status without disrupting communication. "Dynamic Secrets in Communication Security" presents unique security properties and application studies for this technology. Password theft and key theft no longer pose serious security threats when parties frequently use dynamic secrets. This book also illustrates that a dynamic secret based security scheme guarantees impersonation attacks are detected even if an adversary steals a user’s password or their key is lost. Practitioners and researchers working in network security or wireless communications will find this book a must-have reference. "Dynamic Secrets in Communication Security" is also a valuable secondary text for advanced-level students in computer science and electrical engineering.

This self-contained introduction to modern cryptography emphasizes the mathematics behind the theory of public key cryptosystems and digital signature schemes. The book focuses on these key topics while developing the mathematical tools needed for the construction and security analysis of diverse cryptosystems. Only basic linear algebra is required of the reader; techniques from algebra, number theory, and probability are introduced and developed as required. This text provides an ideal introduction for mathematics and computer science students to the mathematical foundations of modern cryptography. The book includes an extensive bibliography and index; supplementary materials are available online. The book covers a variety of topics that are considered central to mathematical cryptography. Key topics include: classical cryptographic constructions, such as Diffie–Hellmann key exchange, discrete logarithm-based cryptosystems, the RSA cryptosystem, and digital signatures; fundamental mathematical tools for cryptography, including primality testing, factorization algorithms, probability theory, information theory, and collision algorithms; an in-depth treatment of important cryptographic innovations, such as elliptic curves, elliptic curve and pairing-based cryptography, lattices, lattice-based cryptography, and the NTRU cryptosystem. The second edition of An Introduction to Mathematical Cryptography includes a significant revision of the material on digital signatures, including an earlier introduction to RSA, Elgamal, and DSA signatures, and new material on lattice-based signatures and rejection sampling. Many sections have been rewritten or expanded for clarity, especially in the chapters on information theory, elliptic curves, and lattices, and the chapter of additional topics has been expanded to include sections on digital cash and homomorphic encryption. Numerous new exercises have been included.
