What I liked about it was the mix of interviews with people who knew Turing in both a personal relationship and also as a professional with their time at Bletchley. The acting and use of psychoanalysis sessions are a good platform with the drama and decent acting on all parts involved. I found myself watching this several times over picking over the names and events. This docudrama gives a less &#8216;dramatized&#8217; impression of Alan Turing as seen in the Imitation game (not a bad film), and I can recommend watching this if you have access to amazon prime or Youtube.<\/p>\n\n\n\n<p>If I to pick out a personal favorite moment it is the demonstration of the apparatus as describe in Turing&#8217;s paper &#8216;<a href=\"https:\/\/www.wolframscience.com\/prizes\/tm23\/images\/Turing.pdf\">on computable numbers, with an application to the entscheidungsproblem&#8217;<\/a>, which shows what an amazing thinker Turing was and really ahead of his time.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Codebreaker: The Alan Turing Story\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/2k9RcMntB6M?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">Codebreaker : The Alan Turing Story on Youtube and Amazon<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Decrypting the Codes &#8211; William Woollard<\/h2>\n\n\n\n<p>This is an enjoyable series covering all aspects of wartime cryptography, ranging from Enigma, The Purple Cipher and how the U boats in the Atlantic where defeated. I found the length of the episodes great to watch during lunch breaks during the week, at 24-25 min long, there is a good mix of evocative historical footage and interviews with key personnel of the topic being covered. I only found one episode had a little too much stock archive footage vs Cryptanalysis material, but that doesn&#8217;t really distract from the overall information provided by this six episode series.<\/p>\n\n\n\n<p>My personal favorite was Episode 3 &#8211; Breaking Purple, and how it went into William Friedmans work on cryptanalysis and successful decryption the Japanese &#8216;purple&#8217; cipher. This leads nicely to the next video, which is thankfully on YouTube !<\/p>\n\n\n\n<p><a href=\"https:\/\/www.imdb.com\/title\/tt27139865\/\" data-type=\"link\" data-id=\"https:\/\/www.imdb.com\/title\/tt27139865\/\">Decrypting the codes <\/a>&#8211; available on Amazon Prime<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Portrait of William F. Friedman<\/h2>\n\n\n\n<p>At 21 minutes long, this video packs alot of information and great interviews into a short time. I searched out Friedman based on his contribution to Cryptanalysis and breaking the Purple code. There is a introduction on how Friedman arrived in America and how he found his way into Cryptanalysis from a entirely different area of study on genetics.<\/p>\n\n\n\n<p>The background on how he met his wife-to-be Elizabeth was nice touch, as they formed a relationship over their areas of interests, and had a nice romantic relationship. As the video progresses it goes into the work he done on code breaking during WWI and WWII, and how breaking &#8216;purple&#8217; had an effect on his mental health.<\/p>\n\n\n\n<p>My favorite part of this video is when the machine, built without seeing the purple cipher machine, is shown and the machine developed by Friedman&#8217;s team used to break it in how close to identical the appearance them is.<\/p>\n\n\n\n<p>I for one will hoping one day to got Friedman&#8217;s library as shown in this gem of a video.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Portrait of William F.

There is a whole series of these videos on Enigma, but this one shows the flaw and explains how it was exploited.<\/p>\n\n\n\n<p>The visual representations of &#8216;blackbox&#8217; of clear text in, cyphertext out, is a good one in my honest opinion. There is also a good way of how the exploit could be corrected, and then went on to developed into an actual encryption method.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Flaw in the Enigma Code - Numberphile\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/V4V2bpZlqx8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">Numberphile &#8211; Flaw in the Engima Code<\/figcaption><\/figure>\n\n\n\n<p>So I hope this week I have provided some interesting things to watch and be entrained about cryptanalysis, next week I will return to explaining how I&#8217;m getting on with the quantum computer simulator, <a href=\"https:\/\/github.com\/nasa\/hybridq\">hybridq<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Whilst last weeks post was all about attending a conference, this weeks post is about things I am doing ready for the upcoming Histocrypt at Oxford and Bletchley.
