A few months ago I picked up a new book called The Block Cipher Companion by Lars Knudsen and Matthew J.B. Robshaw. Shortly thereafter, I posted a review on ethicalhacker.net. I am reposting that review here.
The book is aimed at practioners and aspiring researchers in block cipher cryptography. It is very well-written and accessible (for a cryptography book). I've been interested in cryptography since Applied Crypto came out when I was in high school so I was very excited to finally see a dedicated book on block ciphers.
