什么是NCFB和NOFB模式? [英] what are NCFB and NOFB modes for?
问题描述
我找不到任何地方,当我google它显示这个问题在这里张贴。鉴于这种情况,我想要准确地问:cfb和theb之前这个n是什么意思?
I can't find it anywhere, when I google it it shows this question posted here. Given that situation I want to ask precisely: What this "n" before cfb and ofb means ?
推荐答案
nCFB和nOFB,我可以找到:
This is one reference to nCFB and nOFB that I could find:
请注意,文件的其余部分的CFB和OFB表示8位CFB或OFB模式。 nOFB和nCFB模式表示n位OFB / CFB模式, n用于表示算法的块大小。
...
nOFB:输出反馈模式(以nbit为单位)。 n是算法块的大小。这是一个从块密码实现的同步流密码。它是用于噪声线,因为损坏的密文块不会破坏随后的明文块。此模式以流形式运行。
nOFB: The Output-Feedback Mode (in nbit). n Is the size of the block of the algorithm. This is a synchronous stream cipher implemented from a block cipher. It is intended for use in noisy lines, because corrupted ciphertext blocks do not corrupt the plaintext blocks that follow. This mode operates in streams.
nCFB:密码反馈模式(以n位表示)。 n是算法块的大小。这是从块密码实现的自同步流密码。此模式以流形式运行。
nCFB: The Cipher-Feedback Mode (in nbit). n Is the size of the block of the algorithm. This is a self synchronizing stream cipher implemented from a block cipher. This mode operates in streams.
