2006 CISA Manual Page 405
Lat sentence in the first Paragraph:
A message that has been encrypted twice, first by the sender's secret key and secondly by the receiver's public key achives both authentication and confidentiality objectives.
我想问的是发送者如何产生接受者的public key然后用之去加密信息?
既然是public key,当然就是公开的。具体可以去CA拿到对方的public key |
