For this one, [3]: crcpress.com/Introduction-to-Modern-Cryptography-Second-Edit‌​ion/…, as it is not free.

@Mhy.So many thanks to you. I will try reading your references.

In normal security proof, just challenger and adversary. In security reduction proof, two adversary, $A$ and $B$ algorithms.If $A$ succeeds in breaking security, then $B$ is also sure to break the security. If so?

@Mhy.Why $B$ construct simulation for $A$? If random oracle model is used,simulation is required? How to know the scheme needs to use random oracle model? May be I don't know nature of security proofs by reduction.
