Book excerpt: Distributed systems, characterized by their ability to ensure the execution of multiple transactions across a myriad of applications, constitute a prime platform for building Web applications. However, Web application interactions raise issues pertaining to security and performance that make manual security management both time-consuming and challenging. This thesis is a testimony to the security and performance enhancements afforded by using the autonomic computing paradigm to design an adaptive cryptographic access control framework for dynamic data sharing environments. One of the methods of enforcing cryptographic access control in these environments is to classify users into one of several groups interconnected in the form of a partially ordered set. Each group is assigned a single cryptographic key that is used for encryption/decryption. Access to data is granted only if a user holds the "correct" key, or can derive the required key from the one in their possession. This approach to access control is a good example of one that provides good security but has the drawback of reacting to changes in group membership by replacing keys, and re-encrypting the associated data, throughout the entire hierarchy. Data re-encryption is time-consuming, so, rekeying creates delays that impede performance. In order to support our argument in favor of adaptive security, we begin by presenting two cryptographic key management (CKM) schemes in which key updates affect only the class concerned or those in its sub-poset. These extensions enhance performance, but handling scenarios that require adaptability remain a challenge. Our framework addresses this issue by allowing the CKM scheme to monitor the rate at which key updates occur and to adjust resource (keys and encrypted data versions) allocations to handle future changes by anticipation rather than on demand. Therefore, in comparison to quasi-static approaches, the adaptive CKM scheme minimizes the long-term cost of key updates. Finally, since self-protecting CKM requires a lesser degree of physical intervention by a human security administrator, we consider the case of "collusion attacks" and propose two algorithms to detect as well as prevent such attacks. A complexity and security analysis show the theoretical improvements our schemes offer. Each algorithm presented is supported by a proof of concept implementation, and experimental results to show the performance improvements.

This book was released on 2010-08-05 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptographic access control (CAC) is an approach to securing data by encrypting it with a key, so that only the users in possession of the correct key are able to decrypt the data and/or perform further encryptions. Applications of cryptographic access control will benefit companies, governments and the military where structured access to information is essential. The purpose of this book is to highlight the need for adaptability in cryptographic access control schemes that are geared for dynamic environments, such as the Internet. Adaptive Cryptographic Access Control presents the challenges of designing hierarchical cryptographic key management algorithms to implement Adaptive Access Control in dynamic environments and suggest solutions that will overcome these challenges. Adaptive Cryptographic Access Control is a cutting-edge book focusing specifically on this topic in relation to security and cryptographic access control. Both the theoretical and practical aspects and approaches of cryptographic access control are introduced in this book. Case studies and examples are provided throughout this book.

Available in PDF, EPUB and Kindle. Book excerpt: First in the Field: Breaking Ground in Computer Science at Purdue University chronicles the history and development of the first computer science department established at a university in the United States. The backdrop for this groundbreaking academic achievement is Purdue in the 1950s when mathematicians, statisticians, engineers, and scientists from various departments were searching for faster and more efficient ways to conduct their research. These were fertile times, as recognized by Purdue’s President Frederick L. Hovde, whose support of what was to become the first “university-centered” computer center in America laid the foundation for the nation’s first department of computer science.The book pulls together strands of the story from previously unpublished texts and photographs, as well as published articles and interviews, to provide the first complete historical account of the genesis of the Department of Computer Sciences at Purdue, and its continued growth up to the present. It is a fascinating story with parallels to the “space race,” involving many players, some of whose contributions have gone previously unacknowledged in the heat of the race. Filled with unique historical anecdotes detailing the challenges of legitimizing the new academic field, these stories bring to life the strong convictions of a group of pioneering thinkers that continue to resonate for us today. The raw determination required to transform a computing laboratory that offered early programming courses into a full-fledged computer center and a department offering degrees in computer science characterizes this story of interest to anyone intrigued by the pathways creativity takes in scientific endeavors. It is a story that matters because it was, and is, an ongoing achievement of leadership in education and research in a field that has totally revolutionized our society.
