Cryptography
by Panos Louridas.
M.I.T. Press, 2024 (paperbound, $18.95)

Don’t be misled by the straightforward title—this crash course is an engaging and perfectly paced introduction to cryptography, which computer scientist Panos Louridas mischievously describes as “the art and science of keeping and revealing secrets.” Far from being a language just for hackers, cryptography is vital to the security technologies we use daily, from search histories to gym locker codes. The book covers both the history and principles of the field, complemented by well-designed diagrams that let you test your cryptography skills. In just five chapters, Louridas cracks the code on distilling an intimi­­­dating smorgasbord of topics into a digestible and delightful package.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
