Get rid of your standard authentication media, your smart card, your USB token, your reader and be free to move around with your inseparable companions only, your smart phone and your laptop. With them alone you can fully benefit of strong authentication mechanisms thanks to iEnigma® by charismathics®. The latest cutting edge technology delivered with a completely new user experience. Stop waiting for the IT administrator to set some weird architecture for you, do it independently yourself with some few clicks from your smart phone.
Organizations have enforced smart card authentication in recent years; however this technology is perceived as cryptic and cumbersome by many. iEnigma by charismathics simplifies strong authentication by using smart phones instead. The software is compatible with most PKI applications on computers and smart phones, maintaining the exact security standards. With iEnigma the user can log into his system, sign emails and documents, encrypt communications just as before, saving on buying other hardware and opening new ranges of use cases.
iEnigma is a mobile PKI security solution, absolutely unique and thus patented. Comparable products are either OTP or password based. Companies did not invest in architectures securing the communication between smart phone and laptop or mirroring the strong authentication and digital signature functionalities like a smart card does. With iEnigma, charismathics has translated standard APIs into Bluetooth language, reproducing the exact PKI authentication environment. Providing full TMS compatibility, enabling secure PIN entry and secure channel messaging by default, the software is immediately available for Windows Mobile. iEnigma will soon run on Android, RIM and Apple, also supporting NFC enabled units.
iEnigma simplifies strong authentication opening it to wider range of user groups. Already using smart cards, iEnigma enhances IT security by design, maintaining compatibility to investments made before. Introducing strong authentication, it extensively saves on hardware and is more flexible to use. Organizations save on constantly lost or damaged hardware.
iEnigma bridges user credentials from phones into computers, encrypting the communication channel, allowing PIN entry on the smart phone itself, thus enhancing the security compared to standard smart cards. By supporting applications on the phone, it works remotely as well. The full PKI compatibility allows for unchanged internal processes.
iEnigma re-invents the smart card and is the first strong authentication product that incorporates the expected permutation of corporate IT systems. Supporting common smart phone platforms, it supports applications both on the computer and the smart phone, putting all credentials together in a secure data container on the phone, whether it is the key chain, flash memory, SIM card or additional secure microSD cards such as the Secure Element for NFC operations. All current products are proprietary or represent a niche - no one offers an iEnigma-like 2-in-1 solution and with side benefits such as: full PKI compatibility; significant reductions in hardware cost by replacing tokens and readers using the phone instead; allowing encrypted communication; secure PIN entry; flexible credentials manageable by the user. iEnigma makes full use of the advantages of smart phones and is still fully compatible with all standard processes, APIs, cryptography algorithms and identity management systems. There is no other product opening the range of contactless authentication applications for PKI, such as in hospitals or transportation or payment schemes. The simple user interface opens up strong authentication to small organizations and the single user, reducing identity thefts and phishing attacks within day-to-day use.

For centuries cryptography was used to ensure information secrecy and safe communication. Historically, queer people have had to use various codes and signals to indicate their sexual orientation to each other without being put in danger. Tele_Code aims to shine a light on these hidden parts of history. Inspired by Anne Lister, who used a substitution cypher to write about her relationships with women within her almost 5 million word diaries, the single-player video game takes the player into a maze full of encoded teletext pages, where they must find hints that reveal parts of the cypher and unlock the secret last page.

The Postcard
A postcard published by A.S. bearing an early image of Hill Street and the Town Hall in Richmond, Surrey.
The card was posted in Chelsea on Friday the 15th. June 1906 to:
Monsieur Albert Bach,
8, Via San Nicolao,
Milano,
Italia.
Gordon Welchman
So what else happened on the day that the card was posted?
Well, on the 15th. June 1906, Gordon Welchman was born in Fishponds, Bristol. He was an English mathematician, university professor, Second World War code breaker and author.
Welchman was educated at Marlborough College He then studied mathematics as a scholar at Trinity College Cambridge, from 1925 to 1928.
In 1929, he became a Research Fellow in Mathematics at Sidney Sussex College, Cambridge, a Fellow in 1932, and later Dean of the College.
Bletchley Park
Just before the Second World War, Welchman was invited by Commander Alastair Denniston to join the Government Code and Cypher School at Bletchley Park, in the event of war.
He was one of four early recruits (the others being Alan Turing, Hugh Alexander and Stuart Milner-Barry), who all made significant contributions at Bletchley and who became known as "The Wicked Uncles".
They were also the four signatories to an influential letter, delivered to Winston Churchill in October 1941, asking for more resources for the code breaking work at Bletchley Park. Churchill responded with one of his "Action This Day" written comments.
Welchman devised an enhancement to Alan Turing's improved design of the Polish electromechanical Enigma cipher-breaking machine, the Bombe.
Welchman's enhancement, the "Diagonal Board", which exploited the self-reciprocity of the German Enigma machine, made the device substantially more efficient. The Diagonal Board cut decipher times down from days to mere hours when attacking ciphers generated by the Enigma machine.
Welchman was head of Hut Six, the section at Bletchley Park responsible for breaking German Army and Air Force Enigma ciphers. During his time at Bletchley, Welchman opposed engineer Tommy Flowers' efforts on the Colossus computer (the world's first programmable electronic computer) because Colossus used large numbers of vacuum tubes which were potentially prone to failure.
In 1943, he became assistant director in charge of mechanisation, and also had responsibility for cryptographic liaison with the US.
After WW2
Welchman moved to the United States in 1948 where he taught the first computer course at MIT. He followed this by employment with Remington Rand and Ferranti. Welchman became a naturalised US citizen in 1962.
In 1982 his book 'The Hut Six Story' was published. The U.S. National Security Agency disapproved. The book was not banned, but Welchman was devastated to lose his security clearance and to be forbidden to discuss either the book or his wartime work.
Welchman died on the 8th. October 1985 aged 79 in Newburyport, Massachusetts. His final conclusions and corrections to the story of wartime code breaking were published posthumously in 1986 in the paper "From Polish Bomba to British Bombe: the Birth of Ultra".
The paper was included in the revised edition of 'The Hut Six Story' published in 1997 by M & M Baldwin.

cryptocurrency next generation digital asset is designed to perform the secured transactions using cryptography. Some popular Cryptocurrencies are Bitcoin & Ethereum. The digital currencies can be exchange & transfer from peer to peer without any intervention of Government, Financial Institutions & Banks.
Here are the Enigma machine rotors in place with their cover removed. The code of the day specifies which set of four rotors (from a larger set) should be used and in what order they must be placed. The Enigma machine is completely symmetrical, so all that the message recipient needed to do was set their machine according to the same codebook and to type in the encoded message. The original message emerged, perhaps a little corrupted by human error and noise on the radio.
Mathematics is the core discipline of the National Security Agency. Algebra, number theory, real and complex analysis, probability theory and statistics are used on a daily basis to solve challenging problems in information security and communications technology.

Motorola 3500 SECTEL Model 5DGT3506XA STU-III (Secure Telephone Unit) phone for secure voice/data/video transmission.
Operates in clear (analog) or secure mode over standard "home" telco lines. Requires power supply (left). New price was around $3,500.00... hence, SECTEL 3500? For encrypted mode two sets are required. Will go secure without the key... press the secure button and handshaking starts. Very simple to deploy and use.
Still used for government communications, very effective for protecting sensitive conversations.

Wheel Bank - US Navy Cryptanalytic Bombe
Wheel Banks represent the four rotors used on the German U-boat Enigma. Each column interconnects the four rotors, or commutators, in that column. The top commutator represented the fourth, or slowest, rotor on the Enigma, while the bottom wheel represented the rightmost, or fastest, rotor. The WAVES set the rotors according to the menu developed by the cryptanalysts. The first were set to 00, and each set after that corresponded to the plain/cipher link with the crib (the assumed plain test corresponding to the cipher text.) Usually this meant that each wheel bank stepped up one place from the one on its left. When the machine ran, each bottom rotor stepped forward, and the machine electrically checked to see if the assigned conditions were met. If not, as was usually the case, each bottom wheels moved one more place forward. However, the bottom commutator moved at 850 rpm, so it only took twenty minutes to complete a run of all 456,976 positions.

Steganographia (Secret Writing), by Johannes Trithemius. 1500.
This digital edition Copyright © 1997 by Joseph H. Peterson. All rights reserved.
This is Trithemius' most notorious work. On the surface it is a system of angel magic, but within is a highly sophisticated system of cryptography. It claims to contain a synthesis of the science of knowledge, the art of memory, magic, an accelerated language learning system, and a method of sending messages without symbols or messenger. In private circulation, the Steganographia brought such a reaction of fear that he decided it should never be published. He reportedly destroyed the more extreme portions (presumably instructions for prophecy/divination) but it continued to circulate in mss form and was eventually published posthumously in 1606.
The edition I (James J. O'Donnell) have used is:
1579. Trithemius, Steganographie: Ars per occultam Scripturam
animi sui voluntatem absentibus aperiendi certu, 4to, Darmst. 1621. (Written 1500. First printed edition: Frankfurt, 1606.)

In: FOUR - A Rediscovery of the 'Tetragonus mundus' - Marten KUILMAN (1996/2011). Falcon Press, Heemstede. ISBN 978-90-814420-1-5
(Fig. 127) - Johannes Trithemius (1462 - 1516) is one of the great explorers of the mind. He did not set sail to foreign continents, but tried to find new territories in the human mind with a similar optimism and in the same spirit as the sailors, who headed for the faraway places of the earth. A portrait of Hans Burgkmair from Augsburg around 1510.
The life of the Benedictine friar and abbot Johannes Trithemius (1462 - 1516; fig. 127) can be classified as ‘pivotal’. He was an intriguing and colorful figure, who embodied the spirit of his time. This friend and teacher of Henri Cornelius Agrippa 'charted the arduous route to Heaven along a very narrow and perilous course between two opposing ‘monsters’. The first monster, the Scylla, is a languorous and deliberative state still known by its half-Greek name of acedia (distress of heart, lethargy), and the second monster at the opposite pole, the Charybdis, excessive and indiscreet zeal' (BRANN, 1981; p. 117; BRANN, 1999).
Trithemius was a passionate reformer, teacher, book collector and history-writer. He described, in his 'De Origine Gentis Francorum (1514), a history of the Franks from 439 BC to 841 AD, partly on fictitious evidence (KUELBS & SONKOWSKY, 1987). 'He appears by hindsight to have been a transitional or 'Janus-like' figure', said BORCHARDT (1972) in his article on Trithemius.
His greatest reputation was due to a curious book called the 'Steganographia', published in 1606, but earlier circulating as a manuscript. 'The technical side of this science is very complex, involving pages and pages of elaborate calculations, both astrological and in connection with the numerical values of the angel-names', said Frances YATES (1964, p. 145).
Yates reckoned that Giordano Bruno's preference for the figure thirty was to trace back to Trithemius' 'Steganographia'. In that situation Bruno would have seen a manuscript. YATES (1966, p. 208) pointed to an abstract of this work later made for Bruno, where a list of thirty-one spirits was changed into thirty. Wayne SHUMAKER (1982) emphasized the cryptographic intentions of the 'Steganographia' rather than the demonic mysticism for which it became reputed.
Trithemius is one of the great explorers of the mind in a time, which coincided with the discoveries in the geographical field. Both were generated by an urge to go into extremes, to reach hitherto unknown boundaries. Names like Ficino, Pico della Mirandella, Bruno, Reuchlin, Agrippa and Fludd are just as important as those of Columbus, Vasco da Gama and Magelhaen, although the latter are often more celebrated because of the visible evidence of their discoveries.

STEM stoked for summer…Naval Hospital Bremerton, in conjunction with a partner program between U.S. Naval Undersea Museum, Puget Sound Navy Museum, and Science. Technology, Engineering and Mathematics (STEM) education coordinators at various local commands, distributed STEM-based activity kits to staff members for their children, July 1, 2021. The science kits – each with a colorful lesson page and requisite materials to complete the activity - are primarily suitable for elementary and middle school students. Made available, at no cost, covering a wide range of interests were kits including cryptography, signal flags, polyhedral construction, cribbage and plane spotting; knot tying, chromatography, Cartesian divers and clinometers. Hospital Corpsman 2nd Class (Fleet Marine Force qualified) Fernando A. Perezcarvajal coordinated the command effort. The Navy STEM program supports the Department of the Navy and Marine Corps education and outreach program, providing focus to ‘inspire, engage, and educate the next generation of scientists and engineers, technology and medical professionals. STEM development begins with a outreach programs much like this at the pre-K through 12th grade levels, can continue on through undergraduate and graduate school and also support student advancement into post-doctoral work and all stages of a chosen STEM profession (Official Navy photo by Douglas H Stutz, NHB/NMRTC Bremerton public affairs officer).
