1.4. Enabling Bitstream File Compression and Security

You can optionally enable bitstream compression (and decompression) to reduce the size of your programming bitstream file. The Intel® Quartus® Prime Assembler can generate a compressed bitstream image that reduces configuration file size by 30% to 55% (depending on the design). The FPGA device receives the compressed configuration bitstream, and then can decompress the data in real-time during configuration.

You can separately enable generation of encryption key programming files and user-defined 256-bit security key to protect and authenticate the configuration bitstream. Encryption of the bitstream also offers side-channel protection from non-intrusive attack.
