1.5Tb MACsec Engine
The MACsec Engine implements the latest IEEE 802.1AE specification, providing connectionless data integrity, data origin authenticity and confidentiality on OSI layer 2.
The scalable architecture provides low-latency, line rate acceleration of frame encapsulation, encryption and replay protection. The multi-channel structure makes the engine extremely suitable for use in switches, enabling per-port security with a single IP instantiation. Integration options with either performance or area-optimized AES-GCM IP cores enables a high level of scalability enabling unrivalled trade-off possibilities between throughput, area and latency.
At its very core, the MACsec Engine is completely technology-agnostic and can be integrated in a wide range of FPGA and ASIC technologies. On FPGA, the engine can use vendor-specific optimizations to reach very high throughput goals.
