Mini-course: Secret Sharing, Threshold Cryptography and their Applications

Time:

Venue/Location: Vietnam Institute for Advanced Study in Mathematics (VIASM), 161 Huynh Thuc Khang Street, Lang Ward, Hanoi.

Objective

While secret sharing was originally invented to store data in vaults that could be destroyed or opened in an unauthorized way, today it is the primitive of many cryptographic systems and protocols. To achieve this goal, "shares" of the data are created.

The first line of work focused on making the size of the shares as small as possible. In later work secret sharing became the main primitive in "unconditionally secure" Multi-Party Computation. In Threshold Cryptography the key is shared between parties, which implies that the cryptosystem cannot be used by a single party, but needs, e.g., a majority. Finally, secret sharing can also be used in networks to achieve reliability, privacy and authenticity when the adversary does not have full control of all networks. High school mathematics is the required background. More advanced mathematics used, such as tensor products, and cryptographic concepts will be introduced.
