Some thoughts on the Naibbe cipher.
The Naibbe cipher with 6 tables has 18 different ways to encrypt every plain text letter.
If I have understood correctly how the randon way to choose the encryption works, in the case of simplfied spacing, it will split the size of the sample of every letter in 18 encrypted parts of equal size.
For every plaintext letter: Are there 18 samples of equal size for the unigrams, prefixes and sufixes needed for the encription?
Page 10:
The Naibbe cipher’ sability to disguise a given plaintext bigram in one of 36(6×6) ways through letter-by-lettert ables election is by far its greatest strength
The problem is again the random encryption, the samples of the 36 ways will have the same size, a weakiness.
A non random choice would be better, the preferences of the scribes in the use on some ways over another ones would split the
size of the 36 ways in samples of different sizes, making them more difficult to decrypt
