AES-P Programmable Advanced Encryption Standard Core

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.

The AES-P core is a fully synchronous design and has been evaluated in a variety of technologies, and is available optimized for ASICs or FPGAs.

AES-P reference designs have been evaluated in a variety of technologies. See representative implementation results (in a new pop-up window):

Support

The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.

Verification

The core has been verified through extensive synthesis, place and route and simulation runs. It has also been embedded in several products, and is proven in FPGA technologies.

Export Permits

This core is approved for export to any country, except for the following:

  • Cuba
  • Iran
  • Iraq
  • Libya
  • North Korea
  • Sudan
  • Syria

It is the customer’s responsibility to check with relevant authorities regarding the re-export of equipment containing the AES technology.

Deliverables

The core is available in ASIC (RTLL) and FPGA (netlist) forms, and includes everything required for successful implementation:
