Random House, Delacorte. 263p. illus, bibliog, index. c2001.0-385-73062-4. $8.95. JS Singh summarizes for the curious YA the history and purpose of cryptography. The outline covers the cipher cipher: see cryptography. (1) The core algorithm used to encrypt data. A cipher transforms regular data (plaintext) into a coded set of data (ciphertext) that is not reversible without a key. of Mary Queen of Scots Mary Queen of Scots (Mary Stuart), 1542–87, only child of James V of Scotland and Mary of Guise. Through her grandmother Margaret Tudor, Mary had the strongest claim to the throne of England after the children of Henry VIII. , famous coders and code breakers, mechanized mech·a·nize tr.v. mech·a·nized, mech·a·niz·ing, mech·a·niz·es 1.

Cartouches were also used by the Egyptians. , and computer and privacy encryption. Model codes and directions to Singh's website allow readers to test their understanding of codes and to profit from their reading. Photos acquaint readers with the Rosetta Stone, a Civil War decoding disk, a coded telegram, a Vigenere square, and automatic keyboard scramblers. Back matter lists more classic coding episodes and comments on mathematical methods of sifting patterns from seemingly random numbers and letters. This inexpensive work should spark interest in history and math classes and among patrons of school and public libraries.
