If by external devices you mean other FPGAs, it will be more secure to have separate keys for each FPGA. Extra secure applications use a unique key for each FPGA in the field. If you are talking about storing keys for other things, the Altera FPGA only has room for its own key. You can store keys and anything else in on-chip ram or rom. It will be encrypted by the same method used for the FPGA (which isn't very secure).
