  Recently Hachem et al. formulated a multiaccess coded caching model which
consists of a central server connected to $K$ users via an error-free shared
link, and $K$ cache-nodes. Each cache-node is equipped with a local cache and
each user can access $L$ neighbouring cache-nodes with a cyclic wrap-around
fashion. In this paper, we take the privacy of the users' demands into
consideration, i.e., each user can only get its required file and can not get
any information about the demands of other users. By storing some private keys
at the cache-nodes, we propose a novel transformation approach to transform a
non-private multiaccess coded caching scheme into a private multiaccess coded
caching scheme.
