AES-CCM cores


AES-CCM is an authenticated encryption algorithm designed to provide both authentication and privacy. Developed by Russ Housley, Doug Whiting and Niels Ferguson, CCM is based on two "classic" block cipher modes in combination; Counter Mode (for the encryption) and CBC-MAC (for the authentication). AES-CCM is used in many recent standards such as 802.11, 802.15 and 802.16 wireless, G.9961/G.hn home networking, plus the IEEE 1619.1 standard for tape storage, and is a very compelling choice for many applications.

Helion AES-CCM Solutions

Helion offer a broad selection of AES-CCM solutions, which can be chosen according to your exact requirements. This allows the user to have a very well matched solution, without having to compromise in terms of area or performance.

These high performance AES-CCM cores are available in versions for use in ASIC, Altera, Microsemi (Actel) and Xilinx FPGA, and in common with all Helion IP cores they have been designed with each technology firmly in mind to yield the very best and most efficient results.

Core name 8-bit wide I/O 32-bit wide I/O 128-bit wide I/O
12-cycle AES-CCM N/A N/A
24-cycle AES-CCM N/A
48-cycle AES-CCM N/A
96-cycle AES-CCM N/A

The table above shows the selection of standard AES-CCM solutions currently available from Helion. The core name reflects the nominal number of clock cycles taken to encrypt or decrypt each 16-byte block of information with a 128-bit key; so for example, the 12-cycle core processes each 128-bit AES block in 12 clock cycles, and has a throughput of 10.66Mbps per MHz.

The table also shows that we can offer various interface widths for each of our AES-CCM cores, so that the most appropriate can be chosen for each given application. The table entries marked "N/A" are not available, as they simply don't make sense due to throughput or area constraints.

Other variants are also available, for example we have a special 11-cycle solution specifically designed for use in ASIC, and some lower-area mid-rate solutions not shown which are for use in FPGA, plus a dedicated G.9961/G.hn frame encryption version.

Helion's AES-CCM cores can also support the CCM* algorithm. This is a slightly modified version of the original standard, offering encryption-only and authentication-only modes, and is as used in some of the 802.15 standards (e.g. 802.15.4 / ZigBee™).

Helion was the first company in the world to offer a commercial AES-CCM solution back in 2002, so by now these cores are mature and extremely well proven in production silicon. Since launch they have been further refined to make them even more efficient and easy to use.

To find out how these AES-CCM solutions can be used in your particular application, please contact Helion so that we can discuss the options in more detail.
