Encipher Inye The Encipher Inye is a tablet PC developed by The Encipher Group. It was announced on 8 May 2010 and released in Nigeria that same year. It is powered by a Telechips Tcc8902 ARM 11 800Mhz processor and runs on Android version 2.1 a.k.a. Eclair. It was created by Saheed Adepoju, one of the co-founders.
To encipher or decipher (the system was set up to be reciprocal), a letter could be read off from the reference alphabet to a cylinder alphabet using a slit at the top of the machine.
New York : Farrar, Straus, and Young (Reprinted in 1975 by Octagon Books, a division of Farrar, Straus, and Giroux). He believed Chaocipher was simple, yet unbreakable. Byrne stated that the machine he used to encipher his messages could be fitted into a cigar box. He offered cash rewards for anyone who could solve it.
If a key of 676 length is not long enough, another rotor can be added, resulting in a period 17,576 letters long. In order to be as easy to decipher as encipher, some rotor machines, most notably the Enigma machine, were designed to be symmetrical, i.e., encrypting twice with the same settings recovers the original message (see involution).
The rotor stack from an Enigma rotor machine. The rotors of this machine contain 26 contacts. During World War II (WWII), both the Germans and Allies developed additional rotor machines. The Germans used the Lorenz SZ 40/42 and Siemens and Halske T52 machines to encipher teleprinter traffic which used the Baudot code; this traffic was known as Fish to the Allies.
It was common to encipher a message after first encoding it, to increase the difficulty of cryptanalysis. With a numerical code, this was commonly done with an "additive" - simply a long key number which was digit-by-digit added to the code groups, modulo 10. Unlike the codebooks, additives would be changed frequently. The famous Japanese Navy code, JN-25, was of this design.
After this, the cipher became a regular cipher type in ACA puzzles. In 1987, Noel Currer‐Briggs described the double Playfair cipher used by Germans in World War II. In this case, double Playfair refers to a method using two Polybius squares plus seriation. Even variants of Double Playfair that encipher each pair of letters twice are considered weaker than the double transposition cipher. WGBH Educational Foundation.
The key schedule is a simple linear feedback shift register, which updates every three rounds, resulting in some weak keys (e.g., the zero key). Although the cipher is potentially invertible, the DST protocol makes use of only the encipher mode. When used in the protocol with the 40–24-bit output truncation, the resulting primitive is more aptly described as a Message Authentication Code rather than an encryption function.
One such method, used in the second Beale cipher, replaces the first letter of a word in the book with that word's position. In this case, the book cipher is properly a cipher -- specifically, a homophonic substitution cipher. However, if used often, this technique has the side effect of creating a larger ciphertext (typically 4 to 6 digits being required to encipher each letter or syllable) and increases the time and effort required to decode the message.
The KL-7 was also used by several NATO countries until 1983. An 8-rotor version sent indicators in the clear and was code named POLLUX. The encrypted or decrypted output of the machine was printed on a small paper ribbon. It was the first cipher machine to use the re-entry (re-flexing) principle, discovered by Albert W. Small, which re-introduces the encryption output back into the encryption process to re-encipher it again.
Wireless would play an important role and highlight the potential of this new means of communication, also for military purposes. It was a means with potential – but also with risks because wireless transmissions can easily be intercepted. With regard to the tests that he carried out with Marconi, Luigi Sacco would write, "It is obvious that the enemy can do the same – hence the need to always encipher wireless transmissions."Luigi Sacco, Relazione sugli esperimenti compiuti dal comm.
After a short while, the receiving operators were able to read the messages tapes as fast as Morse code. This mistake was not discovered by the Americans until later, at which time they began to encipher these mechanically transmitted messages. Since it was no longer possible to solve them, work on these messages was discontinued. German experience with these mechanically transmitted messages was the same everywhere, especially in the case of the German Army Ordnance Office.
The operator selects one of the first 7 columns using the key digit and then finds the row in which the key letter occurs. That row in the second set of columns is used to encipher and decipher BATCO messages. The scrambled alphabet in the selected row defines the correspondence between plaintext symbols in the column headings and ciphertext symbols in the individual cells. Note that there are two possible ciphertexts for each plaintext symbol, except for 0, which has four possible ciphertexts.
La Torre is endorsed by Mérida Guitars. In 2014, La Torre collaborated with former Megadeth guitarist Glen Drover on a single called "Discordia". In 2016, La Torre reunited with his former Crimson Glory bandmate Jeff Lords on the latter's current project Dark Matter, singing guest vocals on their sophomore release, Encipher. In 2017, La Torre announced that he was working on his long-awaited solo album, with his friend Craig Blackwell as co-songwriter, while simultaneously recording his third album with Queensrÿche.
On 6 June 1941, Schumacher was drafted in to the German army and Schulze- Boysen found a replacement radio operator in Hans Coppi. Schulze-Boysen persuaded Coppi to take on the task of establishing a radio link to the Soviet Union for the resistance organization. Both Harnack and Coppi were trained by a contact of Korotkov, in how encipher text and how to transmit it, but Coppi failed to send any messages, due to inexperience and technical problems with the radio.
The probability that the wrong key will correctly encipher two or more messages is very low for a good cipher. Sometimes the structure of the cipher greatly reduces the number of plaintext-ciphertext pairs needed, and thus also a large amount of the work. The clearest of these examples is the Feistel cipher using a cyclic key schedule. The reason for this is given a P = (L_0,R_0) the search is for a P_0=(R_0, L_0 \bigoplus F(R_0,K)).
Reciprocal table with keyword IOVE (f. 4v.). Bellaso bitterly writes in 1564, that somebody in that same year was ‘‘sporting his clothes and divesting him of his labors and honors.’’ This is a clear allusion to Della Porta, who printed the reciprocal table in 1563 without mentioning the true inventor. In the introduction of the book he lists thirteen qualities distinguishing his ciphers from other systems, and in a final section he claims priority for these four inventions: # Encipher and decipher with a single countersign.
He started with a tabula recta, a square with 26 letters in it (although Trithemius, writing in Latin, used 24 letters). Each alphabet was shifted one letter to the left from the one above it, and started again with A after reaching Z (see table). Tabula recta Trithemius's idea was to encipher the first letter of the message using the first shifted alphabet, so A became B, B became C, etc. The second letter of the message was enciphered using the second shifted alphabet, etc.
The Stencil Subtractor frame was a ciphered text recyphering tool that was invented by British Army Intelligence Officer and cryptographer John Tiltman and was ready for trial by April 1941 but was not adopted officially by the British Forces until March 1942, and not brought into service until June 1943. It was used together with Subtractor tables, placed on top of the table and the numerical values visible in the gaps of the SS Frame were used to encipher the underlying numerical code (such as the War Office Cipher, RAF cipher or Naval cipher etc).
This key is used to encipher a 40-bit challenge issued by the reader, producing a 40-bit ciphertext, which is then truncated to produce a 24-bit response transmitted back to the reader. Verifiers (who also possess the encryption key) verify this challenge by computing the expected result and comparing it to the tag response. Transponder encryption keys are user programmable, using a simple over-the-air protocol. Once correctly programmed, transponders may be "locked" through a separate command, which prevents further changes to the internal key value.
The material enabled Rejewski to achieve "one of the most important breakthroughs in cryptologic history" by using the theory of permutations and groups to work out the Enigma scrambler wiring. Rejewski could look at a day's cipher traffic and solve for the permutations at the six sequential positions used to encipher the indicator. Since Rejewski had the cipher key for the day, he knew and could factor out the plugboard permutation. He assumed the keyboard permutation was the same as the commercial Enigma, so he factored that out.
Pragyan in 2012 kept the previous year's tagline, "Let's Celebrate Technology". Held from 23 to 26 February 2012, the festival expanded to include more than 50 events, distributed into the categories of Brain Work, Innovation, Chill Pill, Robovigyan, Greengineering, OpeNIT, Management, Engineering Tomorrow and Encipher. Initiatives of this Pragyan included the Chennai Open Quiz, which served as the curtain raising event, Lakshya, a symposium with talks given by civil servants and members of the armed forces. Pengufest, an open coding members' consortium, and Sangam, an inter-departmental technical contest were also new additions to this edition.
An enciphering- deciphering knob on the left side of the machine is set to "encipher". A dial known as the indicator disk, also on the left side, is turned to the first letter in the message. This letter is encoded by turning a hand crank or power handle on the right side of the machine; at the end of the cycle, the ciphertext letter is printed onto a paper tape, the key wheels each advance one letter, and the machine is ready for entry of the next character in the message. To indicate spaces between words in the message, the letter "Z" is enciphered.
An SG-41 ready to encipher text The SG-41 was created under order of the Heereswaffenamt (Inspectorate 7/VI organisation) as a collaboration between German cryptographer Fritz Menzer and Wanderer, a leading typewriter manufacturer. The machine also acquired the nickname "Hitler mill" because of the large crank attached to the side of the unit. Instead of using a lampboard like the Enigma, the SG-41 printed both the plaintext and ciphertext of the message onto two paper tapes. Due to wartime shortages of light metals such as aluminium and magnesium, the SG-41 weighed approximately , which made it unsuitable for the front lines.
With the tagline, "Create.. Innovate.. Scintillate", the sixth edition was celebrated from 25 to 28 February 2010. Pragyan 2010 poster The main events were arranged into eight major clusters, namely, Encipher, Innovation, Brainwork, Chill Pill, Managing Technology, Robovigyan, Engineering Tomorrow and Adrenaline. Crossfire, the panel discussion, was an integral part of the festival. With an eminent set of panellists comprising L S Ganesh, Subramaniam Vincent, Kishore Kumar, Dr Ramesh Jain, Sudhish Kamath and Jagan Jothivel, the event, moderated by Krish Ashok, had the panellists debating the topic ‘Why aren’t we I.D.I.O.T.S (I do it on my own terms)?’ to arrive at a common consensus.
In general these conversations took place between tank and other mechanized units after the beginning of a major engagement. The cryptosystem used to encipher co-ordinates was as a rule quickly solved by comparing the co-ordinates with the intelligence officer's situation reports and by D/F operations. Once this had been achieved, all details of the enemy's intentions became clear soon after the beginning of the attack, inasmuch as messages concerning the attack directions, daily objectives, the course of the front line, casualties, and enemy resistance were being currently intercepted. Some of the tactical commanders carried on conversations without taking more than the above-mentioned insignificant security precautions.
The sending and receiving party had to agree on the specific alignment between the two discs, ensuring that both parties had identical alignment. To encipher a message, the signal officer selected an "adjustment letter" on the inner disc and then made this letter correspond with a preselected numerical code or "key number" on the outer disc. The signal officer would typically give the key numbers to the flagmen without revealing the plain text version of the message. Although this method of encryption was primitive by modern standards, there is no record that the Confederates ever deciphered a Union message that had been processed in this manner.
SIGABA cipher machine at the National Cryptologic Museum, with removable rotor assembly on top In the history of cryptography, the ECM Mark II was a cipher machine used by the United States for message encryption from World War II until the 1950s. The machine was also known as the SIGABA or Converter M-134 by the Army, or CSP-888/889 by the Navy, and a modified Navy version was termed the CSP-2900. Like many machines of the era it used an electromechanical system of rotors in order to encipher messages, but with a number of security improvements over previous designs. No successful cryptanalysis of the machine during its service lifetime is publicly known.
One method of evading signature detection is to use simple encryption to encipher (encode) the body of the virus, leaving only the encryption module and a static cryptographic key in cleartext which does not change from one infection to the next. In this case, the virus consists of a small decrypting module and an encrypted copy of the virus code. If the virus is encrypted with a different key for each infected file, the only part of the virus that remains constant is the decrypting module, which would (for example) be appended to the end. In this case, a virus scanner cannot directly detect the virus using signatures, but it can still detect the decrypting module, which still makes indirect detection of the virus possible.
The manuscript, dated 1846, was said to have been written by the English poet Richard Horne, who shares Horse's birth name. Horse's initiation into the concept of an alternate history came in the early 1980s, when he first encountered professor Ian Halpke, who explained to him that information from the Kabbalah and ancient Jewish texts "hide and encipher the secret", namely, human evolution was aided by extraterrestrial intelligence. According to Horse, Halpke believed the Ark of the Covenant was a nuclear device, and that humans and pigs share compatible genes. Initially, experts determined the manuscript was genuine, as the date Horse picked matched the time period Horne had been alive and active, and the manuscript's topics matched the poet's interests.
When Crimson Glory first went on hiatus after a brief tour in support of Strange and Beautiful with vocalist David VanLanding filling in for Midnight, Lords along with Drenning and Jahkotia formed the short-lived projects Crush (with vocalist Billy Martinez) and Erotic Liquid Culture (with VanLanding), releasing one label-supported, self- titled release under each moniker. Since the early 2010s, Lords has played bass in his current project Dark Matter whose other members have been vocalist Paul Beach, lead guitarist Terry Schambers, drummer Jesse Rojas, and, for a brief spell, rhythm guitarist Chris Baylor. So far, this band has released one full-length album, Terminal Endeavor, and one EP, Encipher; the latter features guest vocals by Todd La Torre on four tracks.
In 1817, he developed a cipher system based on a design by Thomas Jefferson, establishing a method that was continuously improved upon and used until the end of World War II. Wadsworth's cipher system involved a set of two disks, one inside the other, where the outer disk had the 26 letters of the alphabet and the numbers 2–8, and the inner disk had only the 26 letters. The disks were geared at a ratio of 26:33. To encipher a message, the inner disk was turned until the desired letter was at the top position, with the number of turns required for the result transmitted as ciphertext. Due to the gearing, a ciphertext substitution for a character did not repeat until all 33 characters for the plaintext letter had been used.
Wadsworth's cipher, or Wheatstone's cipher, was a cipher invented by Decius Wadsworth, a Colonel in the Ordnance Corps of the United States Army. In 1817, he developed a progressive cipher system based on a 1790 design by Thomas Jefferson, establishing a method that was continuously improved upon and used until the end of World War II. Wadsworth's system involved a set of two disks, one inside the other, where the outer disk had the 26 letters of the alphabet and the numbers 2-8, and the inner disk had only the 26 letters. The disks were geared together at a ratio of 26:33. To encipher a message, the inner disk was turned until the desired letter was at the top position, with the number of turns required for the result transmitted as ciphertext.
The keyboard itself was a large sliding switch, also called permutor board. A signal, coming from a letter key, went through the rotors, back to the permutor board to continue to the printer. The KL-7 was non-reciprocal. Therefore, depending on the Encipher or Decipher position of the permutor board, the direction of the signal through the rotors was changed. The rotor basket had two sets of connectors, two with 26 pins and two with 10 pins, at each end that mated with the main assembly. Both 26 pin connectors were connected to the keyboard to enable the switching of the signal direction through the rotors. Both 10 pin connectors on each side were hard-wired with each other. If a signal that entered on one of the 26 pins left the rotor pack on one of these 10 pins, that signal was redirected back into the rotors on the entry side to perform a new pass through the rotors.
