Instead of the binary field GF(2128), it uses modular arithmetic in GF(''p'') where ''p'' is a Sophie Germain prime 2128 + 12451. SGCM does prevent the specific "weak key" attack described in its paper, however there are other ways of modifying the message that will achieve the same forgery probability against SGCM as is possible against GCM: by modifying a valid n-word message, you can create a SGCM forgery with probability circa n/2^128. That is, its authentication bounds are no better than those of Galois/Counter Mode. SGCM when implemented in hardware has a higher gate count than GCM. However, its authors expect software implementations of SGCM to have similar or superior performance to GCM on most software platforms. ==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「Sophie Germain Counter Mode」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.
