Abstract

Coding theory has been widely applied in fields such as digital communication, multimedia, and distributed storage systems. In this talk, we will use projective planes to construct the generator and parity-check matrix for storage codes. We will study repair performance and update performance of codes. Private Information Retrieval (PIR) is an important application of coding theory in terms of privacy protection. It allows users to retrieve the required information from the database without compromising the query content. In this talk, I will introduce how to use a generator matrix to construct a private information retrieval scheme. Besides, I will give a toy example to show the relation between coding theory and cryptography protocols.
