"How to Share a Secret", by Adi Shamir (1979).

Presented by Nate Gentile.

Abstract: In this paper we show how to divide data D into n pieces in such a way that D is easily reconstructable from any k pieces, but even complete knowledge of k - 1 pieces reveals absolutely no information about D. This technique enables the construction of robust key management schemes for cryptographic systems that can function securely and reliably even when misfortunes destroy half the pieces and security breaches expose all but one of the remaining pieces.

In addition to the main talk by Nate, Marvin Humphrey will present a lightning talk on "When to Share a Secret", discussing Shamir's algorithm in the context of the death of QuadrigaCX CEO Gerald Cotten.
