The IEEE has ratified the 802.16e security standard. It requires an AES core capable of supporting multiple modes including ECB, CBC and CCM. CLP-28: 802.16/WiMAX AES core is based upon Elliptic's high performance, silicon proven AES multi-mode core and has been tailored specifically to the needs of WiMAX developers.
The 802.16/WiMAX AES Core also integrates seamlessly in ARM-based SOCs and enables designers to efficiently balance: power, performance, and silicon area.
