On the Capacity of Secure Distributed Matrix Multiplication
Wei-Ting Chang, Ravi Tandon
Matrix multiplication is one of the key operations in various engineering applications. Outsourcing large-scale matrix multiplication tasks to multiple distributed servers or cloud…
The Capacity of Private Information Retrieval from Uncoded Storage Constrained Databases
Mohamed Adel Attia, Deepak Kumar, Ravi Tandon
Private information retrieval (PIR) allows a user to retrieve a desired message from a set of databases without revealing the identity of the desired message. The replicated databa…
Context-aware Data Aggregation with Localized Information Privacy
Bo Jiang, Ming Li, Ravi Tandon
In this paper, localized information privacy (LIP) is proposed, as a new privacy definition, which allows statistical aggregation while protecting users' privacy without relying on…
Near Optimal Coded Data Shuffling for Distributed Learning
Mohamed A. Attia, Ravi Tandon
Data shuffling between distributed cluster of nodes is one of the critical steps in implementing large-scale learning algorithms. Randomly shuffling the data-set among a cluster of…
Secure Retrospective Interference Alignment
Mohamed Seif, Ravi Tandon, Ming Li
In this paper, the -user interference channel with secrecy constraints is considered with delayed channel state information at transmitters (CSIT). We propose a novel secure ret…
