The disadvantages of most flotation techniques are that the walls of eggs and cysts will often collapse, thus hindering identification. The major disadvantage is that by substituting more than one character of ciphertext for each plaintext value, the length of messages and resulting transmission times are increased. The polyalphabetic substitution is easy to implement It makes frequency analysis more difficult.
