Friday fun with books

“When Bob receives a message from Alice, how does he know it is authentic? If Alice signed her message, this is easy. Alice’s digital signature is enough to convince anyone that the message is authentic”

Book meme:

– Grab the nearest book.
– Open it to page 56.
– Find the fifth sentence.
– Post the text of the sentence in your journal along with these instructions.
– Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.

This is quite sad, but the closest book I have is a copy of “Applied Cryptography” by Bruce Schneier
