The 10th BIU Winter School on Cryptography

Information Theoretic Cryptography

February 17-20, 2020

School Overview

Information-theoretic cryptography aims at achieving security in the presence of computationally unbounded adversaries. This area covers a wide array of topics at the intersection of cryptography, coding theory, information-theory and theory of computation. Information-theoretic protocols provide unconditional security that is not based on unproven computational intractability assumptions, whereas information-theoretic lower-bounds reveal the inherent limitations on the achievability of unconditional security. In addition, information-theoretic methods and reductions lie at the heart of many computational constructions.

In the 10th BIU Winter School on Cryptography, we will study the theory of information-theoretic cryptography. The program will cover the following topics:
private-information retrieval, secret sharing and conditional disclosure of secrets, consensus, and secure multiparty protocols.

The winter school program is designed to teach the topic from its basics up to the latest research. The target audience for the school is graduate students and postdocs in cryptography (we will assume that participants have taken at least one university-level course in cryptography). However, all faculty, undergrads and professionals with the necessary background are welcome. The winter school is open to participants from all over the world; all talks will be in English.

We are sorry that our Chinese colleagues could not come to the winter school due to the outbreak of the new coronavirus. We wish the people of China all the best in these tragic circumstances. All the lectures of the school will be uploaded to Youtube soon after the school is over. Meanwhile, you can watch a live broadcast of the lectures on Dingtalk, on the group 2020 BIU Winter School using this QR code.

(Note that Israel time is 6 hours behind Beijng time)

This winter school is graciously supported by

The BIU Center for Research in Applied Cryptography and Cyber Security in conjunction with the Israel National Cyber Bureau in the Prime Minister’s Office and the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant agreement No. 639813) and the Alter Family.
