The Isom Asemic Code Cipher is a cryptogram code system. This form of cipher embodies geometric and organic shapes. Because it use basic shapes it is an economical and effective method of transmitting confidential information. These devices were often employed by the ancients or by the Medieval philosophers and alchemists. The mystics of the Middle Ages used a system of cryptography which concealed the secrets of the human soul. The Isom Asemic Code Cipher can only be decoded by individuals versed in the deep philosophic principles upon which many mystics based their theories of life. Much information relating to the invisible nature of man is hidden under what seems to be mere scribbles and unrecognizable organic shapes. Every student of symbolism and philosophy should be acquainted with the underlying principles of cryptography. This art furnishes a fascinating method of developing an acute mental awareness. Discrimination and observation are indispensable to the person seeking knowledge, and no study is equal to cryptography as a means of invigorating these powers.

Eight West Point USMA Cadets, in collaboration with both the Greater Cincinnati STEM Collaborative and the West Point Society of Greater Cincinnati, ran a virtual #STEM workshop for 50 middle school students from four different schools. Cadets led the students through cryptography modules developed by CDT Angeline Tritschler and Dr. Lubjana Beshaj, from
The Army Cyber Institute at West Point and West Point Mathematical Sciences
Students worked through several worksheets to code and decode messages using various ciphers like the Caesar cipher and Pigpen cipher, learning about important math concepts like modular arithmetic along the way. CDT Tritschler, who is branching cyber, guided the students through the importance of cyber-hygiene and introduced the history of #cryptography, prior to students breaking out into small groups to create their own version of a scytale, ancient cipher device.” APR 21

Atul Prakash, chair of Computer Science and Engineering (left) and Whitfield Diffie talk to students at at the Beyster building after Whitfield Diffie gave William Gould Dow Distinguished Lecture titled: Post-Quantum Cryptography in Context at Stamps Auditorium on University of Michigan North Campus.
Whitfield Diffie is best known for his discovery of the concept of public-key cryptography, which he developed jointly with Martin Hellman at Stanford University in the mid-1970s. The two shared the ACM Turing Award in 2015 for work that “made cryptography scalable to the Internet and revolutionized the landscape of security.” Retired from positions as head of security for the Canadian telephone system and Sun Microsystems, Diffie is now an Honorary Fellow of Gonville and Caius College in Cambridge. He is a member of the National Academy of Engineering, the Royal Society, and NSA’s Cryptologic Hall of Honor.

Nahbereichs-Zielfernrohr, rifle scope with variable magnification, with 45° eyepieces and roof prisms, Mod. B.Z. scr. E C/1A L, produced by BLC, cryptographic code by Carl Zeiss Jena (according to the disposition of Oberkommando der Wehrmacht) in only 150 specimens, around 1943, used for anti-ship and anti-aircraft aiming and firing of 105 mm guns installed on cruisers, destroyers and battleships of the Kriegsmarine, during the Second World War.
The scope was built with an extremely robust structure, in anodized aluminum, designed to protect lenses, prisms and relative mechanisms inside it, from the strong vibrations deriving from the recoil of the shot, as this optic was installed using a special seat, near the breech of the cannons, which were located inside special command and shooting cabins.
The plate affixed to the bottom left of the structure contains information and technical specifications, in fact, in addition to the manufacturer's brand "BLC" placed above the serial number "171722", there is also the model "B.Z. schr. E C/1A L" - "Binokulares Zielfernrohr mit schragem Einblick" or (pointing binoculars with independent reticles on each single eyepiece and inclined eyepieces), model "C/1A L" where "L" stands for "Links" (left), therefore optics placed on the side left side of the cannon (in fact the optics of these cannons were just 2, one installed on the right side and one on the left side).
In addition, the magnifications and degrees "5x14° - 10x7°" are indicated, which can be selected by turning the appropriate lever, located on the upper part of the structure, where the magnifications, "Vergrößerungs-Wechsel", are shown, therefore it is an optics with 5 and 10 magnifications, with objective lenses of 70 mm (5-10x70). To indicate acceptance by the Kriegsmarine, the Eagle with "M IV/2" and the assignment number "468L". Next to the plate we find the letter "T", in German "Transparenzbelag", which indicates that the lenses are coated with an anti-reflection treatment which improved the transmission of light in the lenses by 80%. This system was developed and patented on November 1, 1935 by Aleksander Smakula, a member of the Zeiss staff in Jena since 1934.
The "Augenabstand" interpupillary movements take place by rotating the knob at the bottom right. The two levers located at the ends of the eyepieces independently activate the insertion of the two relative reticles. On the upper part of the structure there are two levers useful for inserting the filters, "Farbglas Wechsel", "T" (Tag = day - yellow filter) and "N" (Nacht = night - gray filter).
The view is excellent and very bright with both magnifications, and has a very wide field of view thanks to the large eyepieces and objective lenses of no less than 70 mm; collimated prisms and all mechanisms work smoothly. The presence of the original tubes with relative lids should be considered very rare, as it was customary to remove either the lids or even the tubes themselves, purely for a matter of practicality in use. This scope, thus complete, weighs 17.5 kg.
