FAQ - Security Issues

Q. If my application is on a network, how can I make sure the delivery of the bitstream is secure?
A. Xilinx Online applications can exist on public and private networks. In either case all the mechanisms available for software and data security are available for the transport of security. In addition, encryption can be designed into a reconfigurable system.

Q. If I am updating my programmable logic over a network how do I protect against network dropout during upload?
A. Most programmable logic systems use some sort of non-volatile storage (often serial proms) for the initial load or reset image of the bitstream. By simply, duplicating the area of non-volatile storage (harddrive, memory, EEPROM, etc.) and using the duplicate area for the upgrade bit pattern, you can protect the programming of the PLD. Only after the non-volatile is successfully updated would you then program the FPGA.
