While we made every effort to ensure that the information in Top-Down Network Design is timely and accurate, errors do creep in during the production of a 512-page book.
On page 242 of the 3rd edition, the publisher seems to have grabbed the wrong figure for Figure 8-2. They grabbed Figure 8-1 again instead of 8-2. Here's the figure they should have used:
Figure 8-2. Public/Private Key System for Sending a Digital Signature
Notice that Figure 8-1 is different in a subtle but important way.
Figure 8-1. Public/Private Key System for Ensuring Data Confidentiality
