Call for Experts for 3 New X9 Initiatives:

Blockchain Report Audit Framework, “Secret Sharing” Standard, and Data Protection and Breach Notification Standard

ANNAPOLIS, Md. – June 12, 2019

The Accredited Standards Committee X9 Inc. (X9) today announced three new projects for which it seeks expert participants: an effort to develop a framework of blockchain audit guidelines, development of a new standard addressing the practice of “secret sharing,” and creation of a new standard for processes to protect data and report breaches. Potential contributors are invited to get in touch with X9.

Blockchain Report Audit Framework

Enterprise interest in exploring and implementing private blockchain networks both globally and in the U.S. appears to be strengthening. In financial services, audits and assessments are basic and necessary functions, but there are no guidelines that apply to blockchain reports. X9’s Blockchain Auditing workgroup seeks professionals who have experience in blockchain, security or auditing to create a framework of audit guidelines for financial firms using private blockchain solutions, which will be delivered as Technical Report 54. The group’s first meeting will be held Wednesday, July 24, 12-1 p.m. Eastern time; interested parties may write to for meeting information. More details are available on the X9 website.

Secret Sharing Standard

Secret sharing schemes include cryptographic methods for distributing a secret – such as a symmetric key or asymmetric private key — among a group of participants, such that no one person has access to the entire secret. Due to the lack of standards, there are misconceptions and misinformation about secret sharing methods and how to use them. This new standard, designated X9.135, will provide valuable information to product manufacturers, service providers (including cloud services) and end users attempting to secure their cryptographic systems. Individuals with relevant expertise are sought by X9’s Data and Information Security Subcommittee. More detail is online.

Breach Notification and Protection Governance Standard

This new standard, designated X9.141, will define requirements for data protection and breach notification for the financial services industry. This standard will apply to all organizations that handle sensitive payment information, and it will provide a consistent breach notification process to protect consumers and other stakeholders nationwide. X9’s Cybersecurity and Cryptographic Solutions workgroup is looking for individuals with technical knowledge in areas including encryption, identity management, data privacy and data security to assist in drafting the standard. Details can be found on the X9 website.

“These three new projects demonstrate the energy and range of ideas that have surged from X9 members this spring, in a remarkable level of activity and inspiration,” said X9 Executive Director Steve Stevens. “All three initiatives will deliver valuable tools and guidance to the financial services industry, and I urge all interested parties to learn more and join the work.”
