GRAFHEN is a fully homomorphic encryption (FHE) scheme developed by Ravel Technologies designed to secure data in use. It addresses the historical inefficiencies and scaling limitations of traditional FHE by functioning as a highly scalable and noise-free encryption framework. The technology is built to enable continuous data processing, including complex operations like artificial intelligence training, on entirely encrypted datasets without requiring decryption at any point.
By ensuring data remains encrypted during processing, GRAFHEN allows organizations to utilize non-public data and migrate workloads to public cloud infrastructure without exposing the underlying information. It is designed to close the security gaps between encryption at rest and encryption in transit, maintaining absolute data privacy and model secrecy even in the event of a system breach.
