Privacy-Enhancing Cryptography PEC

Special Topics on Privacy and Public Auditability

The “Special Topics on Privacy and Public Auditability” (STPPA) series is organized by the Privacy Enhancing Cryptography (PEC) project in the Cryptographic Technology Group at NIST-ITL-CSD. A main goal of the series is to gather reference material about "PEC tools", which may facilitate future reflections on aspects of standardization and of development of recommendations/guidelines about advanced cryptography, namely for uses related to privacy and public auditability. Each event will include talks on various interconnected topics, aiming to convey basic technical background, incite curiosity, suggest research questions and discuss applications, with an emphasis on the role of cryptographic tools.

Attendance in each event is open and free to the public, but requires registration. Questions, comments or feedback can be sent to "pec-stppa at nist dot gov". Below is a list of past or scheduled events, with links to further details.
