LLP-04: 802.1AE/MACsec PDU Processor
The IEEE has ratified the 802.1AE Media Access Control (MAC) Security standard which offers connectionless user data confidentiality, frame data integrity, and data origin authenticity for Ethernet links. The MACsec security design consists of two elements - an key agreement protocol specified in 802.1X-REV, and a data plane protocol which protects frames traversing the LAN. The data plane protocol defines the frame format for data encapsulation, encryption, and authenticity using the high performance authenticating cipher GCM-AES. Elliptic's LLP-04 is based upon its silicon proven GCM-AES core and support for 802.1X-REV is offered through Elliptic's Ellipsys Middleware.
Key Features:
- Bandwidth up to 45 Gbps full duplex at 375 MHz core clock
- Small internal memory required for classification and security association storage
- Scalable support for multiple Secure Associations and Connectivity Associations
- Flow-through 802.1AE PDU Processing Engine with FIFO fast path interfaces
- Separate LMI interface to control plane
- Gate count of 800K ASIC gates
Applications:
- Ethernet Switches
- Metropolitan Ethernet
- Routers
