Please be advised that a New Work Item Proposal has been loaded to the BSI Standards Development Portal for comment.
Any comments received will be submitted to the national committee “IST/33 – Information security, cybersecurity and privacy protection” for consideration when deciding the UK response to the associated Standards Development Organisation.
Proposal: ISO/IEC NP 25330 – Information Security — Oblivious Transfer
Please visit: ISO/IEC NP 25330
Comment period end date:24/08/2024
Scope
This document specifies terms, various parameters and properties related to oblivious transfer, and establishes a generic model of oblivious transfer.
Purpose
Oblivious transfer (OT) is a cryptographic primitive for secure multiparty computations or key exchange protocols. OT allows one party, called a receiver, to obtain exactly one of two (or more) values from another party, called a sender. The receiver remains oblivious to the other value(s), and the sender is oblivious to which value was received. OT extension protocol reduces expensive asymmetric operations by running a small number of OT instances, i.e., base OT, first and then cheap symmetric operations. In the ISO/IEC JTC 1/SC 27/WG 2 meeting from 8th to 12th of April 2024 in Egham, it was agreed to terminate PWI 24836 (Oblivious Transfer) and initiate a new project on oblivious transfer in a separate project, since oblivious transfer is a cryptographic primitive used for various cryptographic mechanisms such as secure multi-party computation or key management. While new PWIs investigate suitability for inclusion of specific OT schemes in standards, this project will specify terms, various parameters and properties related to oblivious transfer, and establish a generic model of oblivious transfer.
