Three ASCII messages containing English letters and spaces only are encrypted using the one-time pad and the same key. The 10th byte of the first ciphertext is observed to be 0x66, the 10th byte of the second ciphertext is observed to be 0x32, and the 10th byte of the third ciphertext is observed to be 0x23. Let m1 (resp., m2, m3) denote the 10th ASCII character in the first (resp., second, third) message. What is the most you can conclude about m1, m2, and m3?

Question

Answer

Nothing can be determined about m1, m2, or m3 since the one-time pad is perfectly secret.

Answer

Exactly one of m1, m2, or m3 is the space character, but nothing else can be determined.

Answer

m1 is the space character, m2 is the character 't', and m3 is the character 'e'.

Answer

m1 is the character 't', m2 is the space character, and m3 is the character 's'.
