Terrestrial Trunked Radio (TETRA) has become the tool to design any type of public security systems, in particular due to the strongly increased security demands for mobile systems. In this book, the authors show how TETRA can be strongly improved and these improvements will most probably be part of future TETRA standards. The areas examined include channel assignment and multiple access techniques, video transmission, wireless LAN integration, and the establishment of multiple wireless mesh networks. Since the requirements for these networks is security, the authors show that innovative...

With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and sharing-control mechanisms used to protect against unauthorized data access and secure dissemination of sensitive information.

Image data protection and image-based authentication techniques offer efficient solutions for...

Software that covertly monitors user actions, also known as spyware, has become a first-level security threat due to its ubiquity and the difficulty of detecting and removing it. This is especially so for video conferencing, thin-client computing and Internet cafes.

CryptoGraphics: Exploiting Graphics Cards for Security explores the potential for implementing ciphers within GPUs, and describes the relevance of GPU-based encryption to the security of applications involving remote displays. As the processing power of GPUs increases, research involving the use of GPUs...

Company network administrators are compelled today to aggressively pursue a robust network security regime. Network Security Policies and Procedures gives the reader a strong, multi-disciplinary understanding of how to pursue this goal.

This professional volume introduces the technical issues surrounding security as well as how security policies are formulated at the executive level and communicated throughout the organization. Readers will gain a better understanding of how their colleagues on "the other side of the fence" view an organization s security and will...

Multivariate public key cryptosystems (MPKC) is a fast-developing new area in cryptography. In the past 10 years, MPKC schemes have increasingly been seen as a possible alternative to number theoretic-based cryptosystems such as RSA, as they are generally more efficient in terms of computational effort. As quantum computers are developed, MPKC will become a necessary alternative.

Multivariate Public Key Cryptosystems systematically presents the subject matter for a broad audience. The first chapter is an introduction to the basic ideas and early development of both...

Shared resources, such as the Internet, have created a highly interconnected cyber-infrastructure. Critical infrastructures in domains such as medical, power, telecommunications, and finance are highly dependent on information systems. These two factors have exposed our critical infrastructures to malicious attacks and accidental failures. Many malicious attacks are achieved by malicious code or malware, such as viruses and worms. Given the deleterious affects of malware on our cyber infrastructure, identifying malicious programs is an important goal. Unfortunately, malware detectors have...
