If we have a message m (let's say 5 digit integer) and random number r (let's say 6 digit integer) then m+r = 11.

In cryptography, we use this to mask data right?

Is it called randomisation?

Does it follow information theoritic security or something like statistical security??

Is there any proof available that if an adversary doesn't know r then he cannot retrieve m from m+r?
