The -error Capacity of Symmetric PIR with Byzantine Adversaries
Qiwen Wang, Hua Sun, Mikael Skoglund
The capacity of symmetric private information retrieval with messages, servers (out of which any may collude), and an omniscient Byzantine adversary (who can corrupt an…
The Capacity of Private Information Retrieval with Eavesdroppers
Qiwen Wang, Hua Sun, Mikael Skoglund
We consider the problem of private information retrieval (PIR) with colluding servers and eavesdroppers (abbreviated as ETPIR). The ETPIR problem is comprised of messages, …
Secure Private Information Retrieval from Colluding Databases with Eavesdroppers
Qiwen Wang, Mikael Skoglund
The problem of private information retrieval (PIR) is to retrieve one message out of messages replicated at databases, without revealing the identity of the desired message…
Linear Symmetric Private Information Retrieval for MDS Coded Distributed Storage with Colluding Servers
Qiwen Wang, Mikael Skoglund
The problem of symmetric private information retrieval (SPIR) from a coded database which is distributively stored among colluding servers is studied. Specifically, the database co…
Secure Symmetric Private Information Retrieval from Colluding Databases with Adversaries
Qiwen Wang, Mikael Skoglund
The problem of symmetric private information retrieval (SPIR) from replicated databases with colluding servers and adversaries is studied. Specifically, the database comprises …
Symmetric Private Information Retrieval For MDS Coded Distributed Storage
Qiwen Wang, Mikael Skoglund
A user wants to retrieve a file from a database without revealing the identity of the file retrieved at the database, which is known as the problem of private information retrieval…
End-to-End Error-Correcting Codes on Networks with Worst-Case Symbol Errors
Qiwen Wang, Sidharth Jaggi
The problem of coding for networks experiencing worst-case symbol errors is considered. We argue that this is a reasonable model for highly dynamic wireless network transmissions.…
File Updates Under Random/Arbitrary Insertions And Deletions
Qiwen Wang, Viveck Cadambe, Sidharth Jaggi +2
A client/encoder edits a file, as modeled by an insertion-deletion (InDel) process. An old copy of the file is stored remotely at a data-centre/decoder, and is also available to th…
Binary Error Correcting Network Codes
Qiwen Wang, Sidharth Jaggi, Shuo-Yen Robert Li
We consider network coding for networks experiencing worst-case bit-flip errors, and argue that this is a reasonable model for highly dynamic wireless network transmissions. We dem…
