Simon (cipher)

Simon is a family of lightweight block ciphers publicly released by the National Security Agency (NSA) in June 2013. Simon has been optimized for performance in hardware implementations, while its sister algorithm, Speck, has been optimized for software implementations.

Description of the cipher

The Simon block cipher is a balanced Feistel cipher with an n-bit word, and therefore the block length is 2n. The key length is a multiple of n by 2, 3, or 4, which is the value m. Therefore, a Simon cipher implementation is denoted as Simon2n/nm. For example, Simon64/128 refers to the cipher operating on a 64-bit plaintext block (n=32) that uses a 128-bit key. The block component of the cipher is uniform between the Simon implementations; however, the key generation logic is dependent on the implementation of 2, 3 or 4 keys.

Simon supports the following combinations of block sizes, key sizes and number of rounds:

Recurring Saturday Night Live characters and sketches introduced 1990–1991

The following is a list of recurring Saturday Night Live characters and sketches introduced between September 29, 1990, and May 18, 1991, the sixteenth season of SNL.

Larry Roman the Talent Scout

A Dana Carvey sketch. Debuted September 29, 1990.

Middle-Aged Man

A Mike Myers and Chris Farley sketch. Chris Farley portrayed a character known as "Drinking Buddy," Middle-Aged Man's sidekick. Debuted October 20, 1990.

Simon

Simon is a sketch about a young British boy, played by Mike Myers, who likes to draw, and has his own BBC television program, Simon. The sketches always begin by showing the BBC logo with a faux British announcer back-announcing some ridiculously insipid sounding programming on right before it. The show borrows its theme song from a British children's television series called Simon in the Land of Chalk Drawings, though, aside from the concept of a young boy who draws, the premises are completely dissimilar. Simon broadcasts his program from his bathtub, in which he appears to be nude. On the show, Simon displays his drawings (pronounced drawerings in an exaggerated British accent), which he bends over to pick up, whereupon he scolds the audience, by yelling his catch phrases, "Don't look at my bum!" and calling the audience "Bum Lookers!" and "Cheeky Monkeys!"

Simon (game)

Simon is an electronic game of memory skill invented by Ralph H. Baer and Howard J. Morrison, with software programming by Lenny Cope, The original version was manufactured and distributed by Milton Bradley but now the game is currently manufactured by Hasbro. Much of the assembly language was written by Dr. Charles Kapps, who taught computer science at Temple University and also wrote one of the first books on the theory of computer programming. Simon was launched in 1978 at Studio 54 in New York City and was an immediate success, becoming a pop culture symbol of the 1970s and 1980s.

History

Ralph H. Baer and Howard J. Morrison were first introduced to Atari’s game Touch Me at the Music Operators of America (MOA) trade show in 1976. Baer said of the product, “Nice gameplay. Terrible execution. Visually boring. Miserable, rasping sounds.” The original prototype, built by Baer, included the Texas Instruments TMS 1000 microprocessor chip, which was low cost and used by many games of the 1970s. Lenny Cope, who was one of Ralph H. Baer’s partners, worked on the programming code for the core of the game, titled Follow Me at the time. Baer developed the tones of the game, inspired by the notes of a bugle. It was when they pitched the demo, an 8-inch-by-8-inch console, to the Milton Bradley Company that the name of the game was changed to Simon. Simon debuted in 1978 at the cost of $24.95 (equivalent to $91 in 2016) and became one of the top selling toys that Christmas.

Cipher (newuniversal)

Cipher (Jennifer Swann) is a fictional character appearing in American comic books published by Marvel Comics. The character appears in the newuniversal imprint of Marvel Comics, and is one of the four initial superhumans created by the White Event in 2006 (the others being Justice, Nightmask, and Star Brand). newuniversal, designated Earth-555 in the Marvel Comics multiverse, is a re-imagining of the New Universe imprint from the late 1980s. The name Cipher actually refers to two things: a powerful extra-dimensional glyph (tattoo) that confers superhuman powers on a sentient being, and the name of the being that wields the glyph. Cipher is a new superhuman created by Warren Ellis and Salvador Larroca who were inspired by the original Spitfire and the nature of the Star Brand itself (as an extra-dimensional tool of near-unlimited power), combined with strong conceptual ties to Iron Man.

Fictional character biography

Project Spitfire

Essentially nothing is known about Dr. Jennifer Swann’s early life, or where she earned her doctorate. Sometime in the late 1990s or early 2000s she was hired by the NSA to work on Project Spitfire, taking her father’s previous position there. Jennifer continues the work her father, Dr. Joseph Swann, began in 1959 on the H.E.X. (Human Enhancement eXperimental) initiative, an armored exoskeleton that is intended to enable its wearer to combat superhumans with a wide variety of weapons. The original suit was created by Anthony Stark in 1959 who became Cipher in the "The Fireworks" event in 1955, and is an alternate version of Tony Stark (Iron Man) from the mainstream Marvel Universe. Prior to the events in newuniversal #1, neither Jennifer nor her father were able to perfect the design, both suffering broken bones during testing.

Cipher (band)

Cipher is an American hardcore punk, metalcore band that formed in 1996 in Long Beach, New York. Cipher's core line-up consisted of Maurice "Moe" Mitchell (vocals), Danny "Cipher" Bobis (drums), Chris Fry (guitar) and Krys Maniecki (bass).

History

The band's earliest demo's released when they were High School Juniors. These releases were marked by a noticeably more metal and progressive sound than their contemporaries in the Long Island Hardcore scene. Another distinct element of Cipher's sound was Moe Ciphers vocals which were expressed as rhythmic, staccato yells rather than screams which drew some comparisons to Hip hop. Cipher's music addressed socio-political activism, hardcore scene politics and identity.

Later releases became progressively pointed in their political critiques and complex in their musical structure. The release of the EP Protoculture marks a distinct change in artistic direction for Cipher. The four song recording was the first time Cipher put together a compilation of work written for the express purpose of being released as a unit. The outcome was a treatment on race, the trans-Atlantic slave trade, spiritual indecision, and the role of the individual in changing her/his reality.

Cipher (manga)

Cipher is a manga series written and illustrated by Minako Narita. It was adapted into an OVA in 1989.
