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:

Lord of the Flies

Lord of the Flies is a 1954 novel by Nobel Prize-winning English author William Golding about a group of British boys stuck on an uninhabited island who try to govern themselves with disastrous results. Its stances on the already controversial subjects of human nature and individual welfare versus the common good earned it position 68 on the American Library Association’s list of the 100 most frequently challenged books of 1900–1999. The novel is a reaction to the youth novel The Coral Island by R. M. Ballantyne.

Published in 1954, Lord of the Flies was Golding’s first novel. Although it was not a great success at the time—selling fewer than 3,000 copies in the United States during 1955 before going out of print—it soon went on to become a best-seller. It has been adapted to film twice in English, in 1963 by Peter Brook and 1990 by Harry Hook, and once in Filipino (1976).

In 2005 the novel was chosen by TIME magazine as one of the 100 best English-language novels from 1923 to 2005. It was awarded a place on both lists of Modern Library 100 Best Novels, reaching number 41 on the editor's list, and 25 on the reader's list. In 2003, the novel was listed at number 70 on the BBC's survey The Big Read.

Tonight (1957 TV series)

Tonight was a BBC television current affairs programme presented by Cliff Michelmore and broadcast in Britain live on weekday evenings from February 1957 to 1965. The producers were the future Controller of BBC1 Donald Baverstock and the future Director-General of the BBC Alasdair Milne. The audience was typically seven million.

BBC TV background

Tonight was, like Six-Five Special, created by the BBC to fill in the 'Toddlers' Truce' closed period between 6.00pm and 7.00pm (the 'Truce' was officially abolished only a few days before Tonight was first broadcast). Tonight began broadcasting from the Viking studio in Kensington, known by the BBC as 'studio M'. It eventually transferred to one of the main studios in Lime Grove, Shepherd's Bush, west London.

Content and style

The programme covered the arts and sciences as well as topical matters and current affairs. There was a mixture of incisive and light-hearted items: unscripted studio interviews, by Derek Hart, Geoffrey Johnson-Smith and Michelmore himself; and filmed reports. Reporters included Alan Whicker, Fyfe Robertson, Kenneth Allsop, Chris Brasher, Julian Pettifer, Brian Redhead and Polly Elwes.

Tonight (We Live Forever)

"Tonight (We Live Forever)" is a song by English boy band Union J. It was released through Epic Records on 15 August 2014 as the lead single from their second studio album You Got It All – The Album (2014). It was written by Rick Parkhouse, George Tizzard, Josh Wilkinson and Roy Stride, and produced by Red Triangle and Simon Katz.

The song debuted at number 9 in the United Kingdom, becoming the band's third top 10 hit.

Background

In April 2014, Union J left RCA Records and signed with Epic Records.

The single's promotional artwork was revealed by the band via Twitter on 16 June 2014. Speaking to Capital FM on 19 June 2014, Union J said, "This track sums up what Union J are about in terms of our sound and it also reflects who we are together - a group of friends having the time of our lives. It's a happy song that lifts our mood whenever we hear it." The actual artwork was revealed on 18 July.

Critical reception

4Music called the song a "big new anthem". Paul Leake of clickmusic.com gave it three-and-a-half out of five stars and commended the band for "finally [getting] some energy behind them". In a negative review, Amy Davidson of Digital Spy stated that Union J were "playing it safe" and awarded the song two stars.
