one of the authors purposes in the code book is to explain different types of codebreaking to his readers. which line best demonstrates this purpose?\n○ a theoretical breakthrough would be a fundamentally new way of finding alices private key\n○ mathematicians have been studying factoring for centuries, and modern factoring techniques are not significantly better than ancient techniques\n○ a more recent development is the so - called tempest attack, which aims to detect the electromagnetic signals emitted... in a computers display unit\n○ if scientists could build a quantum computer, it would be able to perform calculations with... enormous speed
Answer
# Brief Explanations:
The question asks for a line that shows the author explaining code - breaking. The third option describes a code - breaking method (the tempest attack) which is about detecting electromagnetic signals for code - breaking purposes. The other options focus on mathematical concepts or potential computing power rather than directly on code - breaking methods.
# Answer:
a more recent development is the so - called tempest attack, which aims to detect the electromagnetic signals emitted... in a computer’s display unit
