ISO/IEC 27551 — Information security, cybersecurity and privacy protection — Requirements for attribute-based unlinkable entity authentication [DRAFT]



Attribute-Based Unlinkable Entity Authentication is a mechanism for authenticating unfamiliar parties through the services of a mutually-trusted third party, whilst maintaining privacy of the authenticated.

‘Unlinkable’ refers to the need to be able to handle and process personal information anonymously, in a way that precludes being able to identify the original data subjects from the information being communicated and processed.


Scope of the standard

The standard will define a framework and requirements for ABUEA.


Content of the standard




Currently at Draft International Standard stage.

Was due to be published at the end of this year but more likely to surface in 2021.

Title adjusted to reflect SC 27’s new name.


Personal notes

I ought to catch up with this project!
