![CSA Group CSA Group](/sites/default/files/styles/noi_logo/public/2022-04/CSA_Group_logo_0_0.jpeg.webp?itok=vPDNIHly)
Scope:
This document specifies the processes for secure multiparty computation mechanisms based on the secret sharing techniques which are specified in ISO/IEC 19592-2. Secure multiparty computation based on secret sharing can be used for confidential data processing. Examples of possible applications include collaborative data analytics or machine learning where data are kept secret, secure auctions where each bidding price is hidden, and performing cryptographic operations where the secrecy of the private keys is maintained.
This document specifies the mechanisms including but not limited to addition, subtraction, multiplication by a constant, shared random number generation, and multiplication with their parameters and properties. This document describes how to perform a secure function evaluation using these mechanisms and secret sharing techniques.
Project need:
To align Canadian requirements with those of international standards in the ICT subject area) adoption of new standard. This proposed New Standard is being developed at the request P125 Technical Committee on Cybersecurity. It will provide the industry with the latest requirements in the field of ICT including cybersecurity and software.
Note: The information provided above was obtained by the Standards Council of Canada (SCC) and is provided as part of a centralized, transparent notification system for new standards development. The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.
Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
