DRAMatic Speedup: Accelerating HE Operations on a Processing-in-Memory System
This breakthrough could finally make fully private cloud computing a practical reality.
Deep Dive
Researchers have developed 'DRAMatic,' a new system that uses Processing-in-Memory (PIM) hardware to accelerate Homomorphic Encryption (HE) operations. HE allows computations on encrypted data, enabling confidential cloud computing, but is notoriously slow. By implementing HE directly on UPMEM's PIM chips, DRAMatic significantly closes the performance gap with leading software library Microsoft SEAL, offering major improvements in both runtime and energy efficiency for secure data processing.
Why It Matters
It removes the primary barrier to practical, fully private AI and data analysis in the cloud.
