Question- At first glance it seems as though an exhaustive key search is possible against an OTP system.

Given is a short message, let's say 5 ASCII characters represented by 40 bit, which was encrypted using a 40-bit OTP. Explain exactly why an exhaustive key search will not succeed even though sufficient computational resources are available. This is a paradox since we know that the OTP is unconditionally secure.

That is, describe why a brute-force attack does not work.

You have to answer the paradox, That means answers such as "The OTP is totally secure and thus a brute-force attack does not work" are not valid.
