What Is Gardening in Cryptography and How Does It Work? Gardening in cryptography is the tactic of deliberately provoking an adversary to send a message that contains a known string or highly predictable content. It works by creating an event or rumor that forces specific words, coordinates, or formats to appear in intercepted traffic, giving codebreakers a crib, a piece of known plaintext they can use to test keys or machine settings and accelerate decryption.

Ever heard of “gardening” in codebreaking? It’s the crafty trick of nudging an adversary to include a phrase you already know—so you can crack the rest. From WWII to today, here’s how it works. Curious? #BletchleyPark #cryptanalysis #cryptography #Enigma #knownplaintextattack

What could it be? #Cryptography #Cryptanalysis

Ok new cipher. This one is particularly tricky. Base64, known classical technique used, but not sure which. Doesn’t decode to anything meaningful. Perhaps the message is encoded through shorter than 8 or 6 bit sequences?

The Zodiac Cipher Hoax: Why the Killer's Last Code is a Lie Was the Zodiac Killer a cryptographic genius who left behind a final, unsolvable puzzle... or just a madman who scribbled nonsense he couldn't even solve himself? This podcast cracks open the infamous case of the Zodiac Killer, but we're not just looking at the crimes—we're decoding the mind behind them. We dive deep into the twisted world of the Zodiac ciphers, the taunting puzzles that have haunted investigators and amateur sleuths for over 50 years. You'll learn the stunning story of the Z340 cipher, a complex code that took a team of experts with supercomputers 51 years to break, using a dizzying mix of transposition and substitution. But here's where the real mystery begins. We expose the fierce debate raging in the codebreaking community: are the remaining unsolved ciphers, like the infamous Z13 and Z32, the ultimate challenge from a mastermind? Or are they an elaborate hoax—a jumble of symbols with no message, deliberately designed to be too short to ever be solved, ensuring the Zodiac Killer's final secret would be kept forever? We explore the evidence for both sides, from the sophisticated cryptanalysis used on the solved codes to the frustrating mathematical reality that the shorter ciphers could have infinite solutions. This is the ultimate cold case puzzle, a battle between genius and chaos. So, what do you think? Genius or hoax? Subscribe now and share this with your favorite armchair detective. Join us as we attempt to decode the mind of America's most notorious unsolved serial killer.

The Zodiac Killer's Ciphers: Genius Code or Elaborate Hoax? The Zodiac Killer terrified a nation with his crimes, but his most enduring legacy is a series of cryptic puzzles. Was he a genius cryptographer taunting the world... or was it all just an elaborate, twisted game to make a fool of us all? Welcome to "Hoax Hunters," the podcast that cracks open the world's most chilling codes. In this episode, we're dissecting the infamous Zodiac Killer ciphers. We'll walk you through the stunning amateur codebreaking that solved the Z408 and the 51-year-long battle to crack the Z340. But here's where the story gets controversial. We'll dive into the academic analysis that suggests the Zodiac was no mastermind. Was the complex Z340 a sophisticated code, or a clever piece of misdirection? And more importantly, are the remaining unsolved ciphers, Z13 and Z32, even real? We'll explore the compelling hoax theory—the idea that the killer created unsolvable puzzles just to cement his own dark legend. This is a thrilling, engaging, and highly shareable deep dive into the mind of a killer through the lens of cryptography. Get ready to question everything you thought you knew about one of America's greatest unsolved mysteries. So, was he a mastermind or a master manipulator? Subscribe to "Hoax Hunters" now to explore the hidden messages in history's darkest cases, and share this with your favorite armchair detective to see if you can crack the case.

Implementing Cryptography in AI Systems <p>Interesting research: “<a href="https://eprint.iacr.org/2025/288">How to Securely Implement Cryptography in Deep Neural Networks</a>.”</p> <blockquote> <p><b>Abstract:</b> The wide adoption of deep neural networks (DNNs) raises the question of how can we equip them with a desired cryptographic functionality (e.g, to decrypt an encrypted input, to verify that this input is authorized, or to hide a secure watermark in the output). The problem is that cryptographic primitives are typically designed to run on digital computers that use Boolean gates to map sequences of bits to sequences of bits, whereas DNNs are a special type of analog computer that uses linear mappings and ReLUs to map vectors of real numbers to vectors of real numbers. This discrepancy between the discrete and continuous computational models raises the question of what is the best way to implement standard cryptographic primitives as DNNs, and whether DNN implementations of secure cryptosystems remain secure in the new setting, in which an attacker can ask the DNN to process a message whose “bits” are arbitrary real numbers.</p> <p>In this paper we lay the foundations of this new theory, defining the meaning of correctness and security for implementations of cryptographic primitives as ReLU-based DNNs. We then show that the natural implementations of block ciphers as DNNs can be broken in linear time by using such nonstandard inputs. We tested our attack in the case of full round AES-128, and had success rate in finding randomly chosen keys. Finally, we develop a new method for implementing any desired cryptographic functionality as a standard ReLU-based DNN in a provably secure and correct way. Our protective technique has very low overhead (a constant number of additional layers and a linear number of additional neurons), and is completely practical.</p> </blockquote> <div class="spu-placeholder" style="display:none"></div> <p class="syndicated-attribution">*** This is a Security Bloggers Network syndicated blog from <a href="https://www.schneier.com/">Schneier on Security</a> authored by <a href="https://securityboulevard.com/author/0/" title="Read other posts by Bruce Schneier">Bruce Schneier</a>.
