Hash functions are the cryptographer’s Swiss Army knife. Even though they play an integral part in today’s cryptography, existing textbooks discuss hash functions only in passing and instead often put an emphasis on other primitives like encryption schemes. In this book the authors take a different approach and place hash functions at the center. The result is not only an introduction to the theory of hash functions and the random oracle model but a comprehensive introduction to modern cryptography. After motivating their unique approach, in the first chapter the authors introduce the concepts from computability theory, probability theory, information theory, complexity theory, and information-theoretic security that are required to understand the book content. In Part I they introduce the foundations of hash functions and modern cryptography. They cover a number of schemes, concepts, and proof techniques, including computational security, one-way functions, pseudorandomness and pseudorandom functions, game-based proofs, message authentication codes, encryption schemes, signature schemes, and collision-resistant (hash) functions. In Part II the authors explain the random oracle model, proof techniques used with random oracles, random oracle constructions, and examples of real-world random oracle schemes. They also address the limitations of random oracles and the random oracle controversy, the fact that uninstantiable schemes exist which are provably secure in the random oracle model but which become insecure with any real-world hash function. Finally in Part III the authors focus on constructions of hash functions. This includes a treatment of iterative hash functions and generic attacks against hash functions, constructions of hash functions based on block ciphers and number-theoretic assumptions, a discussion of privately keyed hash functions including a full security proof for HMAC, and a presentation of real-world hash functions. The text is supported with exercises, notes, references, and pointers to further reading, and it is a suitable textbook for undergraduate and graduate students, and researchers of cryptology and information security.

This is a comprehensive description of the cryptographic hash function BLAKE, one of the five final contenders in the NIST SHA3 competition, and of BLAKE2, an improved version popular among developers. It describes how BLAKE was designed and why BLAKE2 was developed, and it offers guidelines on implementing and using BLAKE, with a focus on software implementation. In the first two chapters, the authors offer a short introduction to cryptographic hashing, the SHA3 competition and BLAKE. They review applications of cryptographic hashing, they describe some basic notions such as security definitions and state-of-the-art collision search methods and they present SHA1, SHA2 and the SHA3 finalists. In the chapters that follow, the authors give a complete description of the four instances BLAKE-256, BLAKE-512, BLAKE-224 and BLAKE-384; they describe applications of BLAKE, including simple hashing with or without a salt and HMAC and PBKDF2 constructions; they review implementation techniques, from portable C and Python to AVR assembly and vectorized code using SIMD CPU instructions; they describe BLAKE’s properties with respect to hardware design for implementation in ASICs or FPGAs; they explain BLAKE's design rationale in detail, from NIST’s requirements to the choice of internal parameters; they summarize the known security properties of BLAKE and describe the best attacks on reduced or modified variants; and they present BLAKE2, the successor of BLAKE, starting with motivations and also covering its performance and security aspects. The book concludes with detailed test vectors, a reference portable C implementation of BLAKE, and a list of third-party software implementations of BLAKE and BLAKE2. The book is oriented towards practice – engineering and craftsmanship – rather than theory. It is suitable for developers, engineers and security professionals engaged with BLAKE and cryptographic hashing in general and for applied cryptography researchers and students who need a consolidated reference and a detailed description of the design process, or guidelines on how to design a cryptographic algorithm.

This work presents recent developments in hashing algorithm design. Hashing is the process of creating a short digest (i.e., 64 bits) for a message of arbitrary length, for exam- ple 20 Mbytes. Hashing algorithms were first used for sear- ching records in databases; they are central for digital si- gnature applications and are used for authentication without secrecy. Covering all practical and theoretical issues related to the design of secure hashing algorithms the book is self contained; it includes an extensive bibliography on the topic.

While the some weaknesses have appeared in many hash functions such as MD4, MD5, RIPEMD-family and the series of Secure Hash Algorithm (SHA) families such as, SHA-0, SHA-1, SHA-2, with a number of SHA-3. Thus, National Institute of Standard and Technology (NIST) has suggested different principles to avoid the blunders, and to choice the ideal quality of hash function, that to be a measurement in future of hash function generations. Therefore, the goal of the NIST contenders in SHA-3 between the hash functions is to be chosen as the winner in the end of 2012, or the beginning of 2013. Therefore, for this reason the research addresses the comparative study of the finalist SHA-3 candidates in: design and structure, complexity, with performance and cost, to measure the robustness of the algorithms through the Fundamentals Security Measurement Factors of Hash Function (FSMFHF) of Secure Hash Algorithm (SHA). As a result, from this comprehensive comparison study between the finalist SHA-3 candidates such as; BLAKE, Grostl, JH, Keccak, and Skein, a choice can be made as to the ideal security algorithm against different attacks in suitable structure design of high utilizing of message distribution with high trade-off of speed/ area performance in low cost. Therefore main idea in this research is classify, comparison, and analysis for all five SHA-3 candidates of finalist, and studying the details of these five candidates that in Round 3 by using different structures and different design approaches, and identifying whether the complexity for each design. Thus, this research found a JH hash function is the faster in implementation followed by Grostl hash function, after that Keccak hash function, which gets best security of the hash function applications for different industry structures, as well as supporting a security of different size of data in computer science.

Diploma Thesis from the year 2008 in the subject Computer Science - Applied, grade: 1, Technical University of Berlin, language: English, abstract: Network Measurements play an essential role in operating and developing today's Internet. A variety of measurement applications demand for multipoint network measurements, e.g. service providers need to validate their delay guarantees from Service Level Agreements and network engineers have incentives to track where packets are changed, reordered, lost or delayed. Multipoint measurements create an immense amount of measurement data which demands for high resource measurement infrastructure. Data selection techniques, like sampling and filtering, provide efficient solutions for reducing resource consumption while still maintaining sufficient information about the metrics of interest. But not all selection techniques are suitable for multipoint measurements; only deterministic filtering allows a synchronized selection of packets at multiple observation points. Nevertheless a fillter bases its selection decision on the packet content and hence is suspect to bias, i.e the selected subset is not representative for the whole population. Hash-based selection is a filtering method that tries to emulate random selection in order to obtain a representative sample for accurate estimations of traffic characteristics. The subject of the thesis is to assess which hash function and which packet content should be used for hash-based selection to obtain a seemingly random and unbiased selection of packets. This thesis empirically analyzes 25 hash functions and different packet content combinations on their suitability for hash-based selection. Experiments are based on a collection of 7 real traffic groups from different networks.
