IPsec and TLS Engine IP
Rambus IPsec and TLS security engines deliver the benefits of throughput acceleration in combination with significant CPU offload by performing complete protocol transformations. These multi-protocol engines offer acceleration of IPsec, SSL/TLS/DTLS, MACsec and basic hash and crypto operations at speeds from 100 Mbps up to 800 Gbps in architectures ranging from the traditional Look-Aside engines attached to an AMBA bus system, to more sophisticated and powerful inline packet engines and inline transform engines.
The multi-protocol engines support all common symmetric FIPS-compliant algorithms, the ChaCha20/Poly1305 algorithm, 3GPP algorithms, Chinese algorithms, and various additional optional algorithms for specific applications. The IP integrates with various open-source data planes, such as DPDK and ODP as well as directly with the Linux Crypto APIs.

MACsec Fundamentals
For end-to-end security of data, it must be secured both when at rest (stored on a connected device) and when in motion (communicated between connected devices). For data at rest, a hardware root of trust anchored in silicon provides that foundation upon which all device security is built. Similarly, MACsec security anchored in hardware at the foundational communication layer (Layer 2) provides that basis of trust for data in motion over Ethernet-based networks.
