New Book: Cryptography Engineering
I have a new book, sort of. Cryptography Engineering is really the second edition of Practical Cryptography. Niels Ferguson and I wrote Practical Cryptography in 2003. Tadayoshi Kohno did most of the update work—and added exercises to make it more suitable as a textbook—and is the third author on Cryptography Engineering. (I didn't like it that Wiley changed the title; I think it's too close to Ross Anderson's excellent Security Engineering.)
Cryptography Engineering is a techie book; it's for practitioners who are implementing cryptography or for people who want to learn more about the nitty-gritty of how cryptography works and what the implementation pitfalls are. If you've already bought Practical Cryptography, there's no need to upgrade unless you're actually using it.
EDITED TO ADD (3/23): Signed copies are available. See the bottom of this page for details.
EDITED TO ADD (3/29): In comments, someone asked what's new in this book.
We revised the introductory materials in Chapter 1 to help readers better understand the broader context for computer security, with some explicit exercises to help readers develop a security mindset. We updated the discussion of AES in Chapter 3; rather than speculating on algebraic attacks, we now talk about the recent successful (theoretical, not practical) attacks against AES. Chapter 4 used to recommended using nonce-based encryption schemes. We now find these schemes problematic, and instead recommend randomized encryption schemes, like CBC mode. We updated the discussion of hash functions in Chapter 5; we discuss new results against MD5 and SHA1, and allude to the new SHA3 candidates (but say it's too early to start using the SHA3 candidates). In Chapter 6, we no longer talk about UMAC, and instead talk about CMAC and GMAC. We revised Chapters 8 and 15 to talk about some recent implementation issue to be aware of. For example, we now talk about the cold boot attacks and challenges for generating randomness in VMs. In Chapter 19, we discuss online certificate verification.
