Hmm, I'm not so sure. Rearranging characters could also be a substitution cipher, where each character is replaced with another. I'll have to think this one through a bit more.

Ah, I think Kevin used a transposition cipher. The question mentions he just rearranged the characters to produce the ciphertext, which is the defining characteristic of a transposition cipher.
