You're right. I'll modify that part in the question. Thanks!

comment Diffie-Hellman: Does the size of the prime modulus depend on the potential size of the secret?
Since OTP requires perfect informational secrecy by definition, what would you suggest I refer to this scheme as? Just a "stream cipher"? I referred to it as a One Time Pad because, aside from the fact that information about they keys is leaked, it seems to be the same idea otherwise. Couldn't using a key derivation function open up my system to exhaustive search? Wouldn't there still be an advantage to each message character having its own random shift? In case I didn't mention(and in case it's important), only truly random numbers are being used.

Okay, I read a little more on the discrete logarithm problem. (I swear I couldn't find much specific on it last night. Haha) So would I be correct in saying that the discrete logarithm problem can be solved easily when the prime modulus is small but it becomes increasingly difficult to solve the larger the prime gets?
