Abstract

The demand private coded caching problem in a multi-access network with K users and K caches, where each user has access to L neighbouring caches in a cyclic wraparound manner, is studied. The additional constraint imposed is that one user should not get any information regarding the demands of the remaining users. A lifting construction of demand private multi-access coded caching scheme from conventional, non-private multi-access scheme is introduced. The demand-privacy for a user is ensured by placing some additional keys in a set of caches called the private set of that user. For a given K and L, a technique is also devised to find the private sets of the users.
