这个单词是熵的意思吧！
不过网上对entropy地解释是：Entropy is the measure of the random numbers available from /dev/urandom。
The Linux kernel generates entropy from keyboard timings, mouse movements, and IDE timings and makes the random character data available to other operating system processes through the special files /dev/random and /dev/urandom. This capability was introduced in Linux version 1.3.30.[1]

看来他跟计算机产生的随机数有关。
