Helios Secure Processor IP
General Dynamics Mission Systems
Helios Memory Guard (HMG) and Helios Processing Systems (HPS) are designed to defend against physical attacks on secure data through authentication and encryption.
About
The Helios Memory Guard (HMG) is shimmed between the processor and memory controller to provide just-in-time encryption, decryption, and authentication for all memory write and read requests. HMG also performs decryption and authentication of boot/load-time images encrypted by the Helios Packager prior to deployment. The Helios Processing System (HPS) integrates Helios Memory Guard (HMG) with a processor to provide a fully integrated and validated secure processor IP package. These systems offer Zero Trust enablement, are low risk, use NIST approved algorithms with proven side channel resistance, and feature a simple, drag-and-drop design for easy integration. They are developed and supported by a trusted U.S. DOW supplier.
