Yarrow

Yarrow

El algoritmo Yarrow ("algoritmo de la milenrama") es un generador de números pseudoaleatorios criptográficamente seguro. Su nombre proviene de la planta llamada milenrama, aquilea, o plumerillo, que se usaba como agente aleatorizante en la adivinación I Ching.

Fue diseñado por Bruce Schneier, John Kelsey, y Niels Ferguson de Counterpane Labs (Kelsey et. al, 1999). El algoritmo Yarrow explícitamente no está patentado, es libre, no se requiere licencia para utilizarlo.

Yarrow está incorporado en Mac OS X y FreeBSD para sus dispositivos /dev/random.

Un diseño mejorado de este algoritmo se llamó Fortuna, Ferguson y Schneier lo describen en su libro Practical Cryptography.
