In particular, the DLIN assumption is useful in settings where the decisional Diffie–Hellman assumption does not hold (as is often the case in pairing-based cryptography). The Decision Linear assumption was introduced by Boneh, Boyen, and Shacham.〔Dan Boneh, Xavier Boyen, Hovav Shacham: Short Group Signatures. CRYPTO 2004: 41–55〕 Informally the DLIN assumption states that given $(f,\; \backslash ,\; g,\; \backslash ,\; f^x,\; \backslash ,\; g^y)$, with $f,\; \backslash ,\; g$ random group elements and $x,\; \backslash ,\; y$ random exponents, it is hard to distinguish $(h,\; \backslash ,\; h^)$ (for random $h$) from $(h,\; \backslash ,\; h\text{'})$ (for independently random $h,\; \backslash ,\; h\text{'}$). ==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「Decision Linear assumption」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.
