Bounds on Caching D2D Networks With Secure Delivery
Authors
Abstract
Content caching at the network edge is emerging as a useful solution to mitigate the capacity bottleneck in modern communication architectures. In this work, we study the problem of secure transmission over a caching D2D network where the users can prefetch a portion of popular files in their local cache. Afterwards, users make random request from the library of available files and interact with each other to deliver requested contents from the local cache to satisfy their demands. The communication between the users is wiretapped by an external eavesdropper from whom the communication needs to be kept secret. For this model, we establish a lower bound on the secure transmission rate.
Next, we show that the ratio between lower and upper bounds on secure transmission rate as a function of cache memory is bounded within constant multiplicative gap.
