找到这本书的完整版了。呵呵，贴出来和大家共享。这是本好书，我买了一本作为Verilog的参考书。这本书语法部分集中，便于查阅，此外讲了很多实用的设计思想。最重要的是本书薄，可以完整看完。强烈推荐。 （如果只是查阅，电子版就可以，如要完整学习，建议还是买纸质版的）(Find the full version of this book. I posted and share. This is a good book, I bought a reference book as Verilog. Syntax in this book section focuses on ease of reference, in addition to speaking a lot of useful design ideas. The most important thing is that the book is thin, you can complete reading. Highly recommended. (If you only access the electronic version to complete learning, suggestions or to buy the paper version))

The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.
