Title and Abstract

Beyond Repair: Codes with Random Access
Data reliability and availability are the keystone features of every information system and device. Toward that, coding theory offers useful constructs, mostly for the problem of node/symbol repair.

In the talk we present codes for system setups where both efficient access and extreme reliability are needed, and which are not addressed by existing codes for the repair problem. The new codes are designed for two access modes: one for random access to a code sub-block, and another for high reliability when the sub-block experiences severe error instances. We show how to design codes with random-access properties in both the algebraic-coding and graph (LDPC)-coding settings.
