Security
MISTY1 is a Feistel network with a variable number of rounds (any multiple of 4), though 8 are recommended. The cipher operates on 64-bit blocks and has a key size of 128 bits. MISTY1 has an innovative recursive structure; the round function itself uses a 3-round Feistel network. MISTY1 claims to be provably secure against linear and differential cryptanalysis.

Famous quotes containing the word security:
“... most Southerners of my parents’ era were raised to feel that it wasn’t respectable to be rich. We felt that all patriotic Southerners had lost everything in defense of the South, and sufficient time hadn’t elapsed for respectable rebuilding of financial security in a war- impoverished region.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 1 (1962)
“When kindness has left people, even for a few moments, we become afraid of them as if their reason had left them. When it has left a place where we have always found it, it is like shipwreck; we drop from security into something malevolent and bottomless.”
—Willa Cather (1876–1947)
“We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.”
—John Kenneth Galbraith (b. 1908)
