Crypto Reading Club

Overview

The Cryptography Technology Group in the Computer Security Division hosts Crypto Reading Club talks to foster research and collaboration in cryptography.

When:

Wednesday, once every two weeks, 10:00am-12:00pm (Eastern Time).
Where:
NIST Gaithersburg campus (MD 20899), Building 222, Room B341 or (since 2020) by virtual conference.
Email List:

Meeting reminders will be sent to subscribers of the Crypto Reading Club List.

To be added to the list or suggest a talk, please contact crypto-club-questions (at) nist (dot) gov.

 

The "Crypto Reading Club" was formed in the Computer Security Division at NIST, around 2006/2007, as an informal setting for presentations about cryptography, to share knowledge of old and new results in the literature, and for presentations and conversations about ongoing research and projects. The Crypto reading club thanks the many presenters, internal and external, that have contributed with more than 200 presentations between 2006 and 2021. Lily Chen coordinated the first five years of the series, hosting 50+ talks. In 2011, Meltem Sönmez Turan and Morrie Dworkin joined as hosts. Sara Kerman provided administrative support throughout. Meltem Sönmez Turan hosted around 150 talks till 2021. Luís Brandão became the host in October of 2021. Till early 2020, the crypto reading club meetings took place in person, in the NIST Gaithersburg Campus, usually on Wednesday mornings, sometimes with external visitors. Since then, presentations have been given by video conference.

Due to the covid-19 pandemic, since mid 2020 the talks started to occur via virtual conference. This brought new challenges and opportunities, with respect to attendance and resources.

In this new setting, the crypto reading club differentiates between internal and external talks, as follows:

  • Internal talks: intended for informal presentations and discussions, open only to NIST staff. As traditional "reading club" talks, these will not be recorded.
  • External talks: open to a wider audience, including external to NIST, and advertised via a more open mailing list. These talks may sometimes (upon speaker's consent) be audio-visual recorded by the host, to enable posterior archiving, to serve as a basis of reference material.

There will be some alternation between internal and external talks.
