Final answer:
False. The claim that transposition ciphers, like the one used in the Zimmerman Telegram, are Stream Ciphers is false. Transposition ciphers rearrange the letters of the plaintext, unlike stream ciphers which operate on bits of the plaintext with a keystream.
Step-by-step explanation:
It is false to say that transpositions other than columnar transpositions are examples of stream ciphers. A sort of classical encryption called a transposition cipher involves rearranging the letters in a plaintext. In contrast, a stream cipher uses exclusive-or (XOR) to combine plaintext bits with a pseudorandom cipher digit stream (keystream).
An example of a transposition cipher in use historically is the Zimmerman Telegram. The plaintext is split up into blocks in this cipher, and each block's letters are rearranged in accordance with a set rule. The size of the blocks and the particular letter permutation inside each block can be determined by a keyword that serves as the basis for this rule. It is noteworthy that, in contrast to stream ciphers, these ciphers do not encrypt individual characters or bits in a stream.
