Abstract

The encryption method used to encode the second Beale cipher leads to a ε-Benford’s distribution for the first significant digit of the numbers in the coded message. The relative level of deviation from Benford’s law, ε, is about 0.15 for the second decoded cipher. The other two undeciphered codes show a statistically significant deviation from a 0.15-Benford’s law, suggesting that either ciphers 1 and 3 are fake or the encryption method used to encode them is different from the one used for cipher 2.

摘要

用于对第二个 Beale 密码进行编码的加密方法导致编码消息中数字的第一个有效数字服从ε -Benford 分布。对于第二个解码的密码，与本福德定律的相对偏差ε约为 0.15。另外两个未破译的代码显示出与 0.15-Benford 定律的统计显着偏差，表明密码 1 和 3 是假的，或者用于对它们进行编码的加密方法与密码 2 所使用的方法不同。
