ITU-T Recommendations

Recommendation ITU-T X.1770 establishes technical guidelines for multi-party computation (MPC) and provides a technical standard basis for information and communication technology (ICT) stakeholders to use MPC to protect data in data collaboration and big data analysis scenarios. It also describes applications for which MPC can be used and how it can serve as a reference for ICT stakeholders to develop MPC applications.
Data has become one of the most important assets in ICT. Secure MPC can build trust and security in data collaboration and big data analysis-related areas by balancing usage and protection of data.
Recommendation ITU-T X.1770 includes:
– a technical framework for MPC, in which its elements and the workflow between them is determined;
– security levels of MPC protocols, used in the analysis and determination of the security model and threshold;
– applications of MPC, illustrated by use cases, including an application scenario description and processes, with appropriate security requirement recommendations.
Based on the framework and security levels established in Recommendation ITU-T X.1770, standards for MPC applications in different fields can be determined.
