According to the Wikipedia, and to several of our school study materials, Vigenére autokey ciphers are considered to be self-synchronizing stream ciphers.
If I understand it correctly, the main idea of self-synchronizing ciphers is that they should re-sync in an event of missing characters in the ciphertext because the key only depends on previous N characters.
But, as far as I understand, in Vigenére autokey, every character depends on all of the previous characters being in the right order, isn't that so? So, in an event of a character loss, the rest of the ciphertext after the lost character will never be deciphered correctly.
So, what am I missing? Do I misunderstand self-synchronizing ciphers, or am I missing something about the Vigenere autokey cipher?
