PhD Seminar • Cryptography, Security, and Privacy — Existence of Linear All-or-Nothing TransformsExport this event to calendar

Linear All-or-nothing Transforms are unconditionally secure cryptographic tools with various applications, for example, in secure distributed storage and secure network coding.

A linear (t, s, q)-all-or-nothing transform is a linear function defined on vectors of dimension s with elements from a F_q, which satisfies the condition that the values of any t input co-ordinates are completely undetermined, given only the values of any s - t output co-ordinates. In this seminar, we will discuss the existence of Linear all-or-nothing transforms for different choices of parameters. This includes results obtained by either computer search or analytical constructions.
