Title:
SECRECY SYSTEM AND DECRYPTION METHOD FOR NON-VOLATILE FPGA ON-CHIP DATA STREAM FILE
Document Type and Number:
WIPO Patent Application WO/2018/006556
Kind Code:
A1
Abstract:
Disclosed are a secrecy system and decryption method for a non-volatile FPGA on-chip data stream file. A non-volatile memory module configured in the system only allows a full-erasing operation, and after finishing the full-erasing operation, the non-volatile memory module enters an initial state. Only the operation on the non-volatile memory module in the initial state is effective, and an encrypted area unit is further provided in the non-volatile memory module. Only the decrypted data written in the encrypted area unit in the initial state can make the non-volatile memory module readable, thereby completing the decryption of the system and greatly improving secrecy precision.
