AES: Advanced Encryption Standard Core
Block Diagram
Overview
The AES 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) 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) achieves higher throughput, using a 128-bit datapath and requiring 11/13/15 clock cycles for each data block. Various cipher modes can be supported (ECB, CBC, OFB, CFB, CTR, CCM, GCM and LRW). 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)
- 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 588 ALMs to 2,124 ALMs depending on version
- Configuration: Works with a pre-expended key or can integrate the optional key expansion function
- 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 588 ALMs for the standard version and to 2,124 ALMs for the fast version. On Arria10 device, the core can run at least 100MHz providing a throughput of 290Mbps for the standard version, or 1.16Gbps for the fast version.
