ISO (International Organization for Standardization) is the highest-level international organization for standardization. At the ISO/IEC JTC 1/SC 27 standard conference held on April 12-16, the international standard ISO/IEC PWI 7748 (“Guidelines and practice of privacy protection based on zero-knowledge proofs”) which is mainly promoted by Bingsheng Zhang, Jian Liu, and Kui Ren from Institute of Cyberspace Research, Zhejiang University was successfully established.
Zero-knowledge proofs, as an emerging cryptography technology, is increasingly used for privacy protection. However, due to the lack of unified technical standards, zero-knowledge proofs have high security risks and barriers for landing. This standard (ISO/IEC PWI 7748) mainly regulates the application of zero-knowledge proofs protocol in data processing under various fields and scenarios. This standard is dedicated to protecting user privacy and includes the privacy protection verification system based on zero-knowledge proofs, consisting of its framework, process procedure and module interface.
This standardization project (ISO/IEC PWI 7748) has drawn much attention and support from international experts. At the same time, British expert Patrick Curry and Indian expert Srinivas Poosarla actively participate and promote the project as co-rapporteurs. This is the first time that China has proposed an international standard for zero-knowledge proofs. Moreover, it is also a major breakthrough made by ISO in the field of zero-knowledge proofs standardization.
