Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2008 in the subject Computer Science - Commercial Information Technology, grade: 1.3, University of Regensburg, language: English, abstract: Cryptographic algorithms have nowadays serious impact on many fields of modern life. A good example is the SSL technology, that consists of both symmetric as well as asymmetric cryptography. It is used in thousands of websites like online banking websites to secure transfered data. For the developers of such applications the performance of employing cryptography may be a crucial factor to the success of the complete product. Normally a software developer utilizes cryptographic operations by the usage of precast cryptographic libraries. Therefore, it is interesting to analyze the speed of cryptographic libraries which implement abstract cryptographic algorithms. In the following, we describe our benchmarking of various cryptoalgorithms in different cryptolibraries in different languages on a 32-bit system. In the first part, we outline our preparatory work and our considerations on setting up a fitting benchmarking environment. With this test environment we conducted the benchmarking of seven JAVA cryptolibraries, namely SUN-JCE, Flexiprovider, Bouncy Castle, Cryptix Crypto, IAIK-JCE, GNU crypto and RSA JSafe. Additionally, we benchmarked RSA BSafe, a cryptographic library, which is written in C++, to isolate the influence of the JAVA virtual machine abstraction layer on cryptographic performance. In the second part, we present a condensed illustration of the benchmarking results and our interpretation, for symmetric cryptography, asymmetric cryptography, the generation of hash based massage authentication codes and digital signatures. These results reveal remarkable differences in speed between the algorithms as well as between the different implementations. Also the choice of the underlying operating system has influence on the execution speed of the cryptographic code. In this work we demonstrated

Available in PDF, EPUB and Kindle. Book excerpt: For a long time, there has been a need for a practical, down-to-earth developers book for the Java Cryptography Extension. I am very happy to see there is now a book that can answer many of the technical questions that developers, managers, and researchers have about such a critical topic. I am sure that this book will contribute greatly to the success of securing Java applications and deployments for e-business. --Anthony Nadalin, Java Security Lead Architect, IBMFor many Java developers and software engineers, cryptography is an "on-demand" programming exercise, where cryptographic concepts are shelved until the next project requires renewed focus. But considerations for cryptography must be made early on in the design process and it’s imperative that developers know what kinds of solutions exist. One of Java’s solutions to help bridge the gap between academic research and real-world problem solving comes in the form of a well-defined architecture for implementing cryptographic solutions. However, to use the architecture and its extensions, it is important to recognize the pros and cons of different cryptographic algorithms and to know how to implement various devices like key agreements, digital signatures, and message digests, to name a few.In Java Cryptography Extensions (JCE), cryptography is discussed at the level that developers need to know to work with the JCE and with their own applications but that doesn’t overwhelm by packing in details unimportant to the busy professional. The JCE is explored using numerous code examples and instructional detail, with clearly presented sections on each aspect of the Java library. An online open-source cryptography toolkit and the code for all of the examples further reinforces the concepts covered within the book. No other resource presents so concisely or effectively the exact material needed to begin utilizing the JCE. Written by a seasoned veteran of both cryptography and server-side programming Covers the architecture of the JCE, symmetric ciphers, asymmetric ciphers, message digests, message authentication codes, digital signatures, and managing keys and certificates

Download or read book Java Performance of the Rijndael Encryption Algorithm Across Compilers and Virtual Machines written by Gregory Leavitt Orgill and published by . This book was released on 2005 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rijndael encryption algorithm has recently been published as the Advanced Encryption Standard (AES), a Federal Information Processing Standard, and is being accepted by developers and designers as the algorithm of choice where encryption is required. Java is becoming the language of choice for E-Business applications, many of which require cryptography. The performance of any Java application is dependent on the compiler and virtual machine used to compile and interpret. Prior research has provided performance information for the Rijndael algorithm in Java for specific virtual machines. This research includes the development of a Rijndael implementation in Java. Using Java system calls, the performance of the Rijndael implementation is measured across fifteen compilers and fourteen virtual machines. Through analysis of these benchmarks, the Java performance of the Rijndael algorithm across compilers and virtual machines is produced.

Available in PDF, EPUB and Kindle. Book excerpt: Cryptography, the science of secret writing, is the biggest, baddest security tool in the application programmer's arsenal. Cryptography provides three services that are crucial in secure programming. These include a cryptographic cipher that protects the secrecy of your data; cryptographic certificates, which prove identity (authentication); and digital signatures, which ensure your data has not been damaged or tampered with.This book covers cryptographic programming in Java. Java 1.1 and Java 1.2 provide extensive support for cryptography with an elegant architecture, the Java Cryptography Architecture (JCA). Another set of classes, the Java Cryptography Extension (JCE), provides additional cryptographic functionality. This book covers the JCA and the JCE from top to bottom, describing the use of the cryptographic classes as well as their innards.The book is designed for moderately experienced Java programmers who want to learn how to build cryptography into their applications. No prior knowledge of cryptography is assumed. The book is peppered with useful examples, ranging from simple demonstrations in the first chapter to full-blown applications in later chapters.Topics include: The Java Cryptography Architecture (JCA) The Java Cryptography Extension (JCE) Cryptographic providers The Sun key management tools Message digests, digital signatures, and certificates (X509v3) Block and stream ciphers Implementations of the ElGamal signature and cipher algorithms A network talk application that encrypts all data sent over the network An email application that encrypts its messages Covers JDK 1.2 and JCE 1.2.

Available in PDF, EPUB and Kindle. Book excerpt: "With the growth of digital media, it is becoming more prevalent to find a method to protect the security of that media. An effective method for securely transmitting images is found in the field of Visual Cryptography. While this method is effective for securely transmitting images, many methods have been developed since the first algorithm was proposed in 1994 by Naor and Shamir. A benchmarking scheme is proposed to give the algorithm capabilities, understand the implementation method, evaluate the algorithm development, and provide image reconstruction information. Additionally, the algorithms are ranked according to a Visual Cryptography standard. This would allow an easy way to differentiate between algorithms and determine the ideal algorithm for a given task or project."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Programming multi-core and many-core computing systems Sabri Pllana, Linnaeus University, Sweden Fatos Xhafa, Technical University of Catalonia, Spain Provides state-of-the-art methods for programming multi-core and many-core systems The book comprises a selection of twenty two chapters covering: fundamental techniques and algorithms; programming approaches; methodologies and frameworks; scheduling and management; testing and evaluation methodologies; and case studies for programming multi-core and many-core systems. Program development for multi-core processors, especially for heterogeneous multi-core processors, is significantly more complex than for single-core processors. However, programmers have been traditionally trained for the development of sequential programs, and only a small percentage of them have experience with parallel programming. In the past, only a relatively small group of programmers interested in High Performance Computing (HPC) was concerned with the parallel programming issues, but the situation has changed dramatically with the appearance of multi-core processors on commonly used computing systems. It is expected that with the pervasiveness of multi-core processors, parallel programming will become mainstream. The pervasiveness of multi-core processors affects a large spectrum of systems, from embedded and general-purpose, to high-end computing systems. This book assists programmers in mastering the efficient programming of multi-core systems, which is of paramount importance for the software-intensive industry towards a more effective product-development cycle. Key features: Lessons, challenges, and roadmaps ahead. Contains real world examples and case studies. Helps programmers in mastering the efficient programming of multi-core and many-core systems. The book serves as a reference for a larger audience of practitioners, young researchers and graduate level students. A basic level of programming knowledge is required to use this book.
