Overview

The AES-P encryption IP core implements Rijndael encoding and decoding in compliance with the NIST Advanced Encryption Standard. It processes 128-bit blocks, and is programmable for 128-, 192-, and 256-bit key lengths.Two architectural versions are available to suit system requirements. The Standard version (AES32-P) is more compact, using a 32-bit datapath and requiring 44/52/60 clock cycles for each data block (128/192/256-bit cipher key, respectively). The Fast version (AES128-P) achieves higher throughput, using a 128-bit datapath and requiring 11/13/15 clock cycles for each data block. It can be programmed to use any of the following cypher modes: ECB, CBC, OFB, CFB and CTR.The core works with a pre-expanded key, or with optional key expansion logic.

Features

  • Standards: Satisfies Federal Information Processing Standard (FIPS) Publication 197 from the US National Institute of Standards and Technology (NIST)
  • Configuration: Supports ECB, CBC, OFB, CFB and CTR modes. Works with a pre-expended key or can integrate the optional key expansion function.
  • Throughput: standard/fast version: 2.9/11.6 Mbits/MHz for 128-bit key, 2.5/9.8 Mbits/MHz for 192-bit key, 2.1/8.5 Mbits/MHz for 256-bit key
  • Size: From 756 ALMs to 2,679 ALMs depending on version
  • Deliverables: include test benches, C model and test vector generator

Device Utilization and Performance

The core can be mapped to any Intel® FPGA Family and optimized to suit the particular project's requirements. The AES core synthesizes to 756 ALMs for the standard version and to 2,679 ALMs for the fast version. On Intel Arria® 10 device, the core can run at least 80MHz providing a throughput of 232Mbps for the standard version, or 930 Mbps for the fast version.
