LLP-03: 802.16/WiMAX PDU Processor - WiMAX Mobile Profile

The WiMAX forum has introduced a security profile for mobile WiMAX based on the IEEE 802.16e-2005 standard. The profile implements a single AES-CCM algorithm to lower silicon cost and overall system complexity. The LLP-03 is derived from the silicon proven LLP-02 and is available for immediate licensing. Like the LLP-02, the core offers an inline processing engine which captures traffic, security associations and control words through a single FIFO and operates on them per the reference standard. This greatly simplifies the implementation of complex security functions required for WiMAX.

Key Features:

• Inline symmetric cryptographic functions (compliant to the WiMAX mobile profile 802.16e-2005 PDU processing)
• AES-CCM to the NIST SP 800-38C specification with 128 bit keys
• •Support for insertion and extraction of packet number
• NULL encryption mode support to flow through selected PDUs without performing any security processing
• •Gate count of 44K ASIC gates with standard throughput option
• •Cipher option for increased throughput also available

Applications:

• WiMAX SoCs in base station and subscriber applications
