In a distributed storage system, code symbols are dispersed across space in nodes or
storage units as opposed to time. In settings such as that of a large data center, an important …

Most of our lives are conducted in the cyberspace. The human notion of privacy translates
into a cyber notion of privacy on many functions that take place in the cyberspace. This …

Codes are widely used in many engineering applications to offer robustness against noise.
In large-scale systems, there are several types of noise that can affect the performance of …

In the private information retrieval (PIR) problem, a user wishes to retrieve, as efficiently as
possible, one out of K messages from N non-communicating databases (each holds all K …

Windows Azure Storage (WAS) is a cloud storage system that provides customers the ability
to store seemingly limitless amounts of data for any duration of time. WAS customers have …

Distributed storage systems for large clusters typically use replication to provide reliability.
Recently, erasure codes have been used to reduce the large storage overhead of three …

The underlying fundaments of blockchain are cryptography and cryptographic concepts that
provide reliable and secure decentralized solutions. Although many recent papers study the …

A code over a finite alphabet is called locally recoverable (LRC) if every symbol in the
encoding is a function of a small number (at most r) other symbols. We present a family of …

Private information retrieval (PIR) is the problem of retrieving as efficiently as possible, one
out of K messages from N non-communicating replicated databases (each holds all K …
