How about this:

Use a PIC with more pins so that it can read and write a flash memory
chip. Define a very simple instruction set that the PIC emulates. Have
the "code" stored in the flash RSA encryted. The PIC reads sections of
the code and does them all internally. You have thus created a "secure
processor with external code". I don't think one already exists.
