The IPsec Engine implements RFC4301 and other relevant RFCs, providing confidentiality, connectionless data integrity, data-origin authentication and replay protection on OSI layer 3.
The scalable architecture provides low-latency, line rate acceleration of packet encapsulation, encryption and replay protection. Its modular design not only gives the ability to choose between different cryptographic algorithms, but also provides fine-grained control on classification features, packet formats, and more. Integration with a wide range of performance or area-optimized cryptographic IP cores allows unrivalled trade-off possibilities between throughput, area and latency.
Implementation aspects
At its very core, the IPsec 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.
