I want study more about cryptography reading papers, but I have a problems to understand few concepts: security notions, random oracle model, IND-CCA, ... etc. I began study this concepts by internet: wikipedia, sites etc, but I like have a didactic book to learn this concepts. Please anybody will be able to recommend a didactic book?

Practical Cryptography, by Ferguson and Schneier, is slightly more engaging than a pure reference book, and you might find it more readable than some of the other more technical tomes. Otherwise, there are not many straight-up "story books" that discuss the technology at a bits-and-bytes level.

You will likely find more interesting books in the history category, especially those that discuss wartime codes and cyphers. "The Code Book" by Simon Singh, is a more technical history than most, and is not a bad read. "The Story of Magic: Memoirs of an American Cryptologic Pioneer" by Frank Rowlett, is a first hand account of setting up the United States' code breaking capabilities - it's dry, common in the style of the era, but it's obviously very personal. "Between Silk and Cyanide: A Codemaker's War, 1941-1945", by Leo Marks, is an extremely well-written story, and he brings in a lot of excitement and adventure. Mr. Marks went on to become a successful screenwriter, and has a gift for telling the stories in a very colorful and engaging way.

While the history books are not overly technical, they still present many of the concepts you seem to be asking for.

Modern Cryptography Theory and Practice is what i would suggest , it finely balances theory and practice as title suggests and all the theory concepts are well explained in normal language with ample references
