Hierarchical Cache-Aided Networks for Linear Function Retrieval [PDF]
EntropyIn a hierarchical caching system, a server is connected to multiple mirrors, each of which is connected to a different set of users, and both the mirrors and the users are equipped with caching memories.

Security, Privacy, and Linear Function Retrieval in Combinatorial Multi-Access Coded Caching with Private Caches [PDF]
EntropyWe consider combinatorial multi-access coded caching with private caches, where users are connected to two types of caches: private caches and multi-access caches.

Cache-Aided General Linear Function Retrieval [PDF]
Entropy, 2020 Coded Caching, proposed by Maddah-Ali and Niesen (MAN), has the potential to reduce network traffic by pre-storing content in the users’ local memories when the network is underutilized and transmitting coded multicast messages that simultaneously ...

Robust and Secure Cache-aided Private Linear Function Retrieval from Coded Servers [PDF]
2021 IEEE International Symposium on Information Theory (ISIT), 2021 This work investigates a system where each user aims to retrieve a scalar linear function of the files of a library, which are Maximum Distance Separable coded and stored at multiple distributed servers. The system needs to guarantee robust decoding in the sense that each user must decode its demanded function with signals received from any subset of ...

Security and Privacy in Cache-Aided Linear Function Retrieval for Multi-Access Coded Caching
2022 IEEE Information Theory Workshop (ITW), 2022 A multi-access network consisting of $N$ files, $C$ caches, $K$ users with each user having access to a unique set of $r$ caches has been introduced recently by Muralidhar et al. ("Maddah-Ali-Niesen Scheme for Multi-access Coded Caching," in \textit{Proc. ITW}, 2021).

A General Coded Caching Scheme for Scalar Linear Function Retrieval [PDF]
IEEE Journal on Selected Areas in Information Theory, 2021 Coded caching aims to minimize the network's peak-time communication load by leveraging the information pre-stored in the local caches at the users. The original single file retrieval setting by Maddah-Ali and Niesen has been recently extended to general Scalar Linear Function Retrieval (SLFR) by Wan et al., who proposed a linear scheme that ...
