I was in the RAF from Nov 1993 to Dec 2000. These pictures are from my trade training days at RAF Locking near Weston-Super-Mare, 9 Feb 1994 - 1 Aug 1994. I was on course TCO 114.
At RAF Locking I was trained as a Telecommunications Operator (TCO). A TCO mainly worked in Communication Centres or Signals Unit's, operating a variety of telegraphic, cryptographic, radio, and Morse equipment. TCO's were also trained as Telephonists where they worked in station telephone exchanges. TCO's could also serve in a field comms role at Tactical Communications Wing (TCW) RAF Brize Norton, a role in which I served in early 1998.
I later returned to RAF Locking in 1997 to undertake my Morse course (3 Mar 1997 - 10 Jun 1997); I was on QMC 41.
The operational units I served at were:
RAF Waddington
TCW, RAF Brize Norton (detached to Bahrain)
RAF Coningsby

charismathics exhibits at Infosecurity Europe, London, UK - 19-21 April 2011
charismathics is a global leader in identity management software. Its premier product, the charismathics Smart Security Interface (CSSI), makes it cost-effective and easy for enterprises to integrate multiple authentication solutions into a single, transparent interface. Since 2003, charismathics has pioneered the field of Public Key Infrastructure (PKI), introducing the first PKI client to support Trusted Platform Modules (TPM) and the first PKI client to be fully integrated with pre-boot environments. charismathics also bundles its premier solution with silicon based hardware devices, primarily smart cards and USB cryptographic tokens, where physical and logical security needs also meet when contactless chips and RFID tags are embedded. charismathics is partnering with a growing number of world key players in the field of single sign on, hard disk encryption, digital certificate issuance. Envisioning a revolution in mobile Internet devices, charismathics has turned to this technology as well releasing iEnigma, a software which secures handheld units such as the iPhone, the iPod Touch and most phones featuring Windows Mobile, and provides streamlined two-factor authentication for the enterprise. charismathics offers its security products and services in a variety of industries including building security, banking and finance, healthcare, telecommunications, government and computer manufacturing.

Rewire festival 2015
Korzo, Den Haag
Artist, graduate of Frankfurt’s famed Städelschule, and “experimental computer musician” formerly known as Cracksmurf, Lars Holdhus’s work as TCF explores themes of code, cryptography and privacy. To do this he creates a dizzying, often inspiring mash of visual, sonic, built and written concepts. Boomkat raved about his recent release, 415C47197F78E8… on Liberation Technologies: “Ultimately, words fall well short of adequately describing this stuff; it simply needs to be experienced, fully immersed… pupils dilated.”

Quadratic Voting (QV) aims to bring the efficiency of markets to collective decision making by pricing rather than rationing votes. The proposal has attracted substantial interest and controversy in economics, law, philosophy and beyond. The goal of this conference is to evaluate the promise of Quadratic Voting and to stimulate research on QV from a broad range of perspectives. Leading scholars from disciplines ranging from classics to cryptography will present their work on diverse issues related to QV, including the history of the ideas behind it, practical implementation for market research surveys, objections to the use of money in politics and how QV might have averted political disasters in history. The conference papers will be published in a special issue of Public Choice in 2017, following up on a parallel special issue forty years prior on the use of the Vickrey-Clarke-Groves mechanism for collective decisions.

The title of this artwork is 9C1A66DEBEEA8219C72C359BFABA4E0D62F9D36E29542EF5507BEC4961B74248. This series of text and numbers was generated by the SHA-256 cryptographic hash function. It's up to you to decode this hash and find the original text.
It's impossible to reverse engineer a SHA-256 hash. Enter your guesses into a SHA-256 hash generator and see if your hash matches this artwork.
Bitcoin mining uses the SHA-256 as the Proof of work algorithm. Each bitcoin block is identified by a unique SHA-256 hash.
This artwork is identified by its unique hash, which is created from its original identity. Decode the hash, and you'll decode the original title.

Sci-Tech Summer Camp Cryptography
SciTech is a STEM-focused community based program that is designed to foster awareness of and interest in STEM related careers.
Dr. Frank Ingram will facilitate a math session on cryptography (codebreaking) using mathematics.
Shot with my 40D, with my 70-200 F4/L IS with Kenko extension tubes, all mounted on a Gitzo 3540xls tripod with Arca Swiss monoball Z1sp and a Wimberley quick release plate.
I knabbed this little guy for a special sale price from ncix.com (they normally go for around $22 or so. I'll probably be grabbing a decent usb webcam to use this little ball of light to generate cryptographically secure random numbers. Why? Because I can, and I've got some time on my hands to play with that sorta ultra-geeky (well, ok nerdy) stuff.
Michele Reilly is a scientist, an artist, and a systems thinker whose work resists easy classification. She trained in architecture and art at Cooper Union, where she began building intelligent machines and quickly became fascinated by the logic behind them. That curiosity drew her into mathematics, cryptography, macroeconomics, and eventually quantum physics. Her path has been shaped less by credentials than by the depth of her questions.
At MIT, where she teaches in the Department of Mechanical Engineering, Michele works at the intersection of computation and the structure of spacetime. She explores how information flows through the universe, drawing from Claude Shannon’s foundational theories and extending them into the quantum realm. Her research is ambitious, but it is rooted in careful thinking. She is not interested in speculation for its own sake. She wants to know what can be built, what can be measured, and what will last.
In 2016, she co-founded Turing, a quantum technology startup focused on building portable quantum memories and tools for long-distance quantum communication. She works closely with physicist Seth Lloyd on designing the scalable, robust systems needed to move quantum computing from theory into practice. The work is intricate and deliberate, building slowly toward a future that she sees as both beautiful and unfamiliar.
Michele is also a storyteller. Her science fiction series Steeplechase has received awards at Cannes and other international festivals. It reflects her belief that narrative and science are not separate pursuits, but parallel ways of exploring the unknown. In her teaching, she brings these strands together, guiding students through exercises that combine quantum theory, creative writing, and world-building. One of her courses, supported by MIT’s Center for Art, Science and Technology, invites students to imagine speculative futures grounded in scientific inquiry.
On her arm is a tattoo of Alan Turing. It is not ornamental. It is a quiet tribute to a thinker whose life and work continue to shape her own. Turing’s dedication to truth, structure, and the ethical weight of technology is a constant presence in her thinking. She carries it with her, quite literally.
The portrait above was made at The Interval at the Long Now Foundation in San Francisco. Michele is seated beside a polished table that reflects her image. Behind her stands the Orrery, a planetary model designed to keep time for ten thousand years. The setting reflects the spirit of her work. She is grounded in the present but always thinking forward, asking how we might live in ways that honor complexity, care, and continuity. She does not speak often about legacy. She speaks about attention, about precision, and about the discipline of staying with difficult questions until they begin to yield something real.
Father of Computer Science and Artificial Intelligence, Logician, Mathematician, and Codebreaker who joined the University of Manchester in 1948. He was prosecuted because he was gay* in 1952, died in 1954.

* He was convicted of "gross indecency", a legal term that was originally used to criminalise sexual activity between men. Turing had been prosecuted for consensual private homosexual acts. In 2017, under the Alan Turing law, all men convicted of gross indecency due to consensual, private sexual acts were pardoned. en.wikipedia.org/wiki/Alan_Turing

This is in the cryptography section of the Intrepid. I think these are all radio receivers. I couldn't get close enough to actually read what they were.
