("Lecture Notes on Cryptography" ). Summer course on cryptography, MIT, 1996-2001〕 Historically, cryptanalysis of block ciphers has focused on key-recovery, but security against these sorts of attacks is a very weak guarantee since it may not be necessary to recover the key to obtain partial information about the message or decrypt message entirely. Modern cryptography uses more robust notions of security. Recently, indistinguishability under adaptive chosen-ciphertext attack (IND-CCA2 security) has become the "golden standard" of security.〔Boneh, Dan. Advances in Cryptology -- Crypto 2003 : 23rd Annual International Cryptology Conference, Santa Barbara, California, Usa, August 17-21, 2003, Proceedings. Berlin: Springer, 2003.〕 The most obvious key-recovery attack is the exhaustive key-search attack. But modern ciphers often have a key space of size $2^$ or greater, making such attacks infeasible with current technology. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Key-recovery attack」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
