Grid computing is one of the most powerful techniques that can achieve a high acceleration for cryptographic algorithms. This approach makes the digital signature attractive for adoption by businesses to secure their documents. In this thesis, we propose and develop an application for digital signature cryptography using enterprise grid middleware called Alchemi. High Performance Approach for Digital Signature that is Called Grid Signature is applied through the separation of the message, into blocks and encrypting each block to get cipher blocks. Inside Alchemi, it computing the hash code is used for cipher blocks in independent Alchemi executors and any result of computing hash 160 bit is added to other in exclusive disjunction logic gate; the result is called Grid Hash . The evaluation of performance in the grid signature depends on three relations: file size; block size and number of executors. For each file the sign or verify was carried on 1, 2, 3, 4 and 5 executor nodes. So the performance is reached when using file size 82MB and under running 4 executors to 137.96% of speed up over the single processor version.

Cybersecurity has traditionally been the purview of information technology professionals, who possess specialized knowledge and speak a language that few outside of their department can understand. In our current corporate landscape, however, cybersecurity awareness must be an organization-wide management competency in order to mitigate major threats to an organization’s well-being—and be prepared to act if the worst happens. With rapidly expanding attacks and evolving methods of attack, organizations are in a perpetual state of breach and have to deal with this existential threat head-on. Cybersecurity preparedness is a critical and distinctive competency, and this book is intended to help students and practitioners develop and enhance this capability, as individuals continue to be both the strongest and weakest links in a cyber defense system. In addition to providing the non-specialist with a jargon-free overview of cybersecurity threats, Dr. Chatterjee focuses most of the book on developing a practical and easy-to-comprehend management framework and success factors that will help leaders assess cybersecurity risks, address organizational weaknesses, and build a collaborative culture that is informed and responsive. Through brief case studies, literature review, and practical tools, he creates a manual for the student and professional alike to put into practice essential skills for any workplace.
High-Performance Computing (HPC) delivers higher computational performance to solve problems in science, engineering and finance. There are various HPC resources available for different needs, ranging from cloud computing– that can be used without much expertise and expense – to more tailored hardware, such as Field-Programmable Gate Arrays (FPGAs) or D-Wave’s quantum computer systems. High-Performance Computing in Finance is the first book that provides a state-of-the-art introduction to HPC for finance, capturing both academically and practically relevant problems.
This publication explores not only the evolution of computer security but future developments anticipated in the field. Many aspects of this increasingly significant area are considered, including the relationship between international standards and organizational security in both small and large systems. The importance of constantly improving and updating training and education is also discussed. Contributions are sourced from a broad base of world-renowned specialists and the book will therefore be of prime interest to researchers, developers and managers in the academic and industrial spheres alike.
Rapid technological advancement has given rise to new ethical dilemmas and security threats, while the development of appropriate ethical codes and security measures fail to keep pace, which makes the education of computer users and professionals crucial. The Encyclopedia of Information Ethics and Security is an original, comprehensive reference source on ethical and security issues relating to the latest technologies. Covering a wide range of themes, this valuable reference tool includes topics such as computer crime, information warfare, privacy, surveillance, intellectual property and education. This encyclopedia is a useful tool for students, academics, and professionals.
