CCM6 802.16e (WiMAX)AES Core
|
| |
General Description
|
Key Features
|
| |
|
Implementation
of the new WLAN security standard (802.16e) requires
the NIST standard AES cipher in CTR and CBC modes (a.k.a.
CCM) for encryption and message authentication. The
CCM6 AES core is tuned for 802.16e applications. The core contains the base AES core
AES1 and is available for immediate licensing.
The design is fully synchronous and available in both
source and netlist form. |
Small size:
from
8,900 ASIC gates at 802.16 data speeds
Completely self-contained: does not require external
memory
Includes encryption, decryption, key expansion and
data interface
Support for Counter Mode Encryption (CTR) operation
and CCM extensions (Counter Mode with CBC MAC)
Support for CMAC and MBS-CTR modes
Flow-through design with header parsing

Function Description
|
| |
|
The Advanced Encryption Standard (AES) algorithm is a
NIST data encryption standard as defined in the
http://csrc.nist.gov/publications/fips/fips197/fips-197.pdf.
The core is designed for flow-through operation, with byte-wide
input and output interfaces. CCM6 key precedes the frame in the flow of data.
CCM6 supports CCM and MBS-CTR modes for both encryption and
decryption, and CMAC authentication.

Export Permits
|
| |
US Bureau of Industry and Security has assigned
the export control classification number 5E002 to our AES
core. The core is eligible for the license exception ENC
under section 740.17(A) and (B)(1) of the export
administration regulations. See the
licensing basics page,
for links to US government sites and more details. |
