24.幂数加密

先看一下什么是幂数加密

二进制幂数加密法，由于英文字母只有26个字母。只要2的0、1、2、3、4、5次幂就可以表示31个单元。通过用二进制幂数表示字母序号数来加密。

二进制幂数加密法就是应用这个原理，由于英文字母只有26个字母，由公式可知，只要2的0、1、2、3、4、5次幂就可以表示31个单元。通过用二进制幂数表示字母序号数来加密。例如

明文： d o n o t p u l l a l l y o u r e g g s i n o n e b a s k e t

字母序号：4 15 14 15 20 16 21 12 12 1 12 12 25 15 21 18 5 7 7 19 9 14 15 14 5 2 1 19 11 5 20

由于4=2^2 所以D加密过之后是2；15=2^0+2^1+2^2+2^3所以O加密后是0123。同理得到上述明文的加密后的密文

密文：2 0123/123 0123 24/4 024 23 23/0 23 23/034 0123 024 14/02 012 012 014/03 123 /0123 123 02/1 0 014 013 02 24
