In spite of strong advances in confidential computing technologies, critical information is encrypted only temporarily – while not in use – and remains unencrypted during computation in most present-day computing infrastructures. The inability to keep critical information encrypted during computation can hinder the ability to fully share data and extract its maximum value.
Fully Homomorphic Encryption (FHE) is a cryptographic method to protect information confidentiality by enabling the processing of encrypted data without decrypting. However, the application of FHE carries a severe “performance tax” that is difficult to overcome with existing hardware.
The need for revolutionary hardware to enable FHE applications was identified by DARPA in the context of the DPRIVE program. As part of the DPRIVE program execution, Intel and Microsoft are realizing a platform to make FHE technologies more accessible by developing revolutionary hardware and software stack. Furthermore, the team is committed to the development of international standards and best practices. Overall, the initiative can enable unprecedented, cost-effective FHE performance, and pave the path for industrial deployment.
