Revisiting Deniability in Quantum Key Exchange via Covert Communication and Entanglement Distillation
Arash Atashpendar, G. Vamsi Policharla, Peter B. Rønne +1
We revisit the notion of deniability in quantum key exchange (QKE), a topic that remains largely unexplored. In the only work on this subject by Donald Beaver, it is argued that QK…
A Proof of Entropy Minimization for Outputs in Deletion Channels via Hidden Word Statistics
Arash Atashpendar, David Mestel, A. W. Roscoe +1
From the output produced by a memoryless deletion channel from a uniformly random input of known length , one obtains a posterior distribution on the channel input. The differen…
CryptoRec: Privacy-preserving Recommendation as a Service
Jun Wang, Afonso Arriaga, Qiang Tang +1
Recommender systems rely on large datasets of historical data and entail serious privacy risks. A server offering Recommendation as a Service to a client might leak more informatio…
From Clustering Supersequences to Entropy Minimizing Subsequences for Single and Double Deletions
Arash Atashpendar, Marc Beunardeau, Aisling Connolly +4
A binary string transmitted via a memoryless i.i.d. deletion channel is received as a subsequence of the original input. From this, one obtains a posterior distribution on the chan…
