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.
The go-to dictionary (and encyclopedia) for crypto novices and
experts alike. It covers technical terms found in modern software
analysis, such as 'block cipher,' while providing context for
historical references like the 'crypto wars,' sharing amusing
anecdotes (ever hear of the 'Hasty Pudding Cipher'?), and
describing major conferences in the field, including Eurocrypt and
Real World Crypto. Includes descriptions of the field's most
innovative techniques, like threshold cryptography, as well as
those developed in the context of blockchain applications, in a
broadly approachable way.
Serious Cryptography is the much anticipated review of modern
cryptography by cryptographer JP Aumasson. This is a book for
readers who want to understand how cryptography works in today's
world. The book is suitable for a wide audience, yet is filled with
mathematical concepts and meaty discussions of how the various
cryptographic mechanisms work. Chapters cover the notion of secure
encryption, randomness, block ciphers and ciphers, hash functions
and message authentication codes, public-key crypto including RSA,
Diffie-Hellman, and elliptic curves, as well as TLS and
post-quantum cryptography. Numerous code examples and real use
cases throughout will help practitioners to understand the core
concepts behind modern cryptography, as well as how to choose the
best algorithm or protocol and ask the right questions of vendors.
Aumasson discusses core concepts like computational security and
forward secrecy, as well as strengths and limitations of
cryptographic functionalities related to
