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 of our AES-GCM Ip core 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. The BA415 addresses a wide range of networking applications where security is a concern. 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.
