Order-Optimal Coded Caching With File and Demand Privacy
Han Fang, Nan Liu, Wei Kang
We study coded caching with joint file and demand privacy: each user recovers its requested file while learning nothing about the remaining files and the other users' requests join…
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…
Secure D2D Coded Caching under Radius-Limited Connectivity via Lifting
Han Fang, Nan Liu, Wei Kang
Secure device-to-device (D2D) caching requires users to generate delivery signals from their own caches and to recover their requested files without learning the other files. We co…
Characterizing the Optimal Memory-Rate Tradeoff in Secure Coded Caching for Small Buffer or Small Rate
Han Fang, Nan Liu, Wei Kang
We consider the secure coded caching problem proposed by Ravindrakumar et. al where no user can obtain information about files other than the one requested. We first propose three…
