Secure Multi-Access Coded Caching: A Lifting Approach
Han Fang, Qinyi Lu, Nan Liu +1
We construct secure cyclic multi-access coded caching schemes by re-encoding the caches of a secure single-access scheme and reusing its multicast message unchanged. For a library…
Improved Characterization of the Memory-Rate Tradeoff for Demand-Private Coded Caching With Multiple Demands
Qinyi Lu, Nan Liu, Wei Kang +1
We consider a coded caching problem with multiple demands under a privacy constraint. In this problem, a server with access to files serves users over a shared link, and ea…
Demand Private Coded Caching: Small Cache Size
Qinyi Lu, Nan Liu, Wei Kang +1
We investigate the demand private coded caching problem, which is an coded caching problem with files, users, each equipped with a cache of size , and an additio…
Capacity of Hierarchical Secure Coded Gradient Aggregation with Straggling Communication Links
Qinyi Lu, Jiale Cheng, Wei Kang +1
The growing privacy concerns in distributed learning have led to the widespread adoption of secure aggregation techniques in distributed machine learning systems, such as federated…
Demand Private Coded Caching: the Two-File Case
Qinyi Lu, Nan Liu, Wei Kang
We investigate the demand private coded caching problem, which is an coded caching problem with files, users, each equipped with a cache of size , and an additio…
