Which of the following statements about cipher based encryption is NOT true?

The statement that Caesar cipher is a stronger encryption technique than one-time pads is not true. In fact, the Caesar cipher represents a relatively simple form of substitution cipher that relies on a fixed amount of shifting of letters, which makes it vulnerable to various forms of cryptanalysis. The strength of encryption methods is often evaluated based on their resistance to being broken without the key.

One-time pads, on the other hand, provide a level of security that can be proven to be unbreakable when they are implemented correctly. This means that if the key used in a one-time pad is genuinely random, as long as the plaintext, and used only once, it is theoretically impossible to decipher the encrypted message without having the corresponding key. Because of this inherent strength, one-time pads surpass simpler ciphers like the Caesar cipher in terms of security.

Thus, the comparison generated in the statement is incorrect, emphasizing that the one-time pad is a significantly stronger encryption technique than the Caesar cipher, which is easily broken with modern computational techniques.
