initialization vector(IV)
In cryptography, a binary vector used in the initial input block in the cipher feedback (CFB) and output feedback (OFB) modes of operation and as the randomizing block for the first data block in the cipher block chain (CBC) mode of operation.; 加密技術(shù)中的一種用二進(jìn)制表示的向量,用于在密碼反饋(CFB)和輸出反饋(OFB)操作方式 下的初始輸入塊,并且作為密碼塊鏈接(CBC)操作方式下第一個數(shù)據(jù)塊的隨機(jī)化塊。
