AES-CCM: Advanced Encryption Standard Core
Block Diagram
Overview
The AES-CCM 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-CCM) 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-CCM) achieves higher throughput, using a 128-bit datapath and requiring 11/13/15 clock cycles for each data block. CCM stands for Counter with CBC- MAC mode. CCM is a generic authenticate-and-encrypt block cipher mode. CBC-MAC is utilized to generate an authentication string while CTR mode is used to encrypt.
Features
- Standards: Satisfies Federal Information Processing Standard (FIPS) Publication 197 from the US National Institute of Standards and Technology (NIST)
- Size: From 482 ALMs to 4,502 ALMs depending on version and target device
- 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-CCM core synthesizes to 518 ALMs for the standard version and to 1,682 ALMs for the fast version. On a Stratix® V device, the core can run at least 200MHz providing a throughput of 582 Mbps for the standard version, or 2.32 Gbps for the fast version.
