Private information retrieval (PIR) is a key building block in many privacy-preserving
systems. Unfortunately, existing constructions remain very expensive. This paper introduces …

Many systems possess the flexibility to serve requests in more than one way, such as
distributed storage systems that store multiple copies of the data. In such systems, the …

Codes in the sum-rank metric have attracted significant attention for their applications in
distributed storage systems, multishot network coding, streaming over erasure channels …

A locally recoverable code (LRC code) is a code over a finite alphabet, such that every
symbol in the encoding is a function of a small number of other symbols that form a …

With the diversification of pit mine slope monitoring and the development of new
technologies such as multisource data flow monitoring, normal alert log processing system …

Distributed storage can store data in multiple devices or servers to improve data security.
However, in today's explosive growth of network data, traditional distributed storage scheme …

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

Internet-of-Things (IoT) environment has a dynamic nature with high risks of confidentiality,
integrity, and availability violations. The loss of information, denial of access, information …

Codes for storage systems aim to minimize the repair locality, which is the number of disks
(or nodes) that participate in the repair of a single failed disk. Simultaneously, the code must …

A code is said to be an r-local locally repairable code (LRC) if each of its coordinates can be
repaired by accessing at most r other coordinates. When some of the r coordinates are also …
