The MACsec, IPsec and SSL\/TLS\/DTLS protocols are the primary means of securing data in motion (communicated between connected devices). These protocols can be anchored in hardware or implemented in software as part of an end-to-end security architecture.

Rambus IPsec and TLS<\/a> 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.<\/p>

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.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
