At Rambus, we create cutting-edge semiconductor and IP products, spanning memory and interfaces to security, smart sensors and lighting.
Protecting data in use
Rambus inline memory encryption and inline cipher engines protect data in use including applications for secure memory transactions between hosts and attached memory at high throughput with low latency. Differential Power Analysis (DPA) protection and Data Path Integrity is available as an option on most solutions as a counter to DPA and related side-channel attacks.

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. This white paper provides fundamental information on each of these protocols including their interrelationships and use cases.
