101地特四等 計算機概論
以下有關資訊安全的敘述何者錯誤?
(A)數位信封(digital envelop)的觀念就是使用收訊人的公開金鑰(public key)
對某些機密資料作加密,收訊人收到後再使用自己的私密金鑰(private key)解密
而讀取資料 (B)傳訊人使用其私密金鑰(private key)將原始訊息進行加密,
即得到此訊息的數位簽章(digital signature)
(C)數位憑證(digital certificate)內含有憑證持有者的公開金鑰(public key)
(D)SSL(Secure Socket Layer)架構於TCP傳輸層(TCP transport layer)之上,
應用層(application layer)之下
答案是:B
數位簽章不是用傳訊者的私鑰加密產生數位簽章嗎?對方收到再用傳送方的公鑰去解密
,所以應該B是對的啊??
