Efforts on Standardizing Fully Homomorphic Encryption at ISO/IEC

July 25, 2023


Rosario Cammarota - Intel Labs


Abstract. Fully Homomorphic Encryption (FHE) empowers users to delegate computation to the cloud. It allows the processing of encrypted inputs without the need for decryption and returns encrypted outputs to intended recipients. However, the industry's adoption of FHE has been slow due to several reasons. First, processing encrypted data incurs a significant performance tax, even for simple operations. Cipher operations can be several orders of magnitude slower than clear-text operations on existing hardware. Second, there is a shortage of automation tools for translating data and applications to enable FHE. Third, there is a lack of standards and best practices for secure FHE deployment, particularly in combination with other confidential computing techniques. In this talk, we will concentrate on the progress made in standardizing FHE under the guidance of ISO/IEC JTC1 SC27, the Joint Technical Committee of the International Organization for Standardization and the International Electrotechnical Commission, since its inception.
