AES-GCM is an authenticated encryption algorithm designed to provide both authentication and privacy. The GCM is based on CTR Mode (Counter Mode) for encryption and a Galois field multiplication for authentication.
The unique architecture enables very high throughput from 10 Gbps to 100 Gbps while maintaining an optimal resource usage. The scalability of the IP enables to find a trade-off between resources, performance and technology. It is very easily portable to ASIC and FPGA (Xilinx, Altera) technologies. The BA415 addresses a wide range of networking applications where security is a concern.

- Scalable and flexible AES-GCM Engine
- The AES-GCM engine is a scalable solution, which provides a full range of solutions from 10 Gbps to 100 Gbps.
- The BA415 AES-GCM includes key management and context switching. The optimized context switching enables handling of multiple virtual streams of data within a single core.
- The key can be selected for each packet independently. The advanced pipelined architecture of the AES-GCM core enables small data packets to be processed without penalty on performance.
- The BA415 is an easy-to-use solution with predictable resources and performances on ASIC and FPGA. The simple FIFO interfaces make it easy to integrate in any design.
