On Quantum Advantage in Information Theoretic Single-Server PIR
quantum complexity private information retrieval specious security
2019/3/4
In (single-server) Private Information Retrieval (PIR), a server holds a large database DBDB of size nn, and a client holds an index i∈[n]i∈[n] and wishes to retrieve DB[i]DB[i] without revealing ii t...
Revisiting Single-server Algorithms for Outsourcing Modular Exponentiation
modular exponentiations secure outsourcing
2018/11/2
We investigate the problem of securely outsourcing modular exponentiations to a single, malicious computational resource. We revisit recently proposed schemes using single server and analyse them agai...
Privately Outsourcing Exponentiation to a Single Server: Cryptanalysis and Optimal Constructions
Secure outsource computation Cryptanalysis Coppersmith methods
2016/3/21
We address the problem of speeding up group computations in cryptography using a single untrusted computational resource. We analyze the security of an efficient protocol for securely outsourcing mult...
Efficient and Secure Delegation of Group Exponentiation to a Single Server
cryptographic protocols Single Server
2016/1/3
We consider the problem of delegating computation of group operations from a computationally weaker client holding an input and a description of a function, to a {\em single} computationally stronger ...
A Linear Lower Bound on the Communication Complexity of Single-Server Private Information Retrieval
Communication Complexity of Single-Server Private Information Retrieval
2008/5/29
We study the communication complexity of single-server Private Information Retrieval (PIR) protocols that are based on fundamental cryptographic primitives in a black-box manner.
