In this paper we propose efficient schemes enabling groups of users of a mobile network to communicate anonymously with respect to an adversarial party (i.e, other users, network managers, and so on). Each user can start a group communication, and his identity, as well as the identities of the other members of the group, are not revealed even if several other parties of the system collude. We consider two network settings and, for each of them, we propose an efficient and secure scheme.

Abstract
In this paper we propose efficient schemes enabling groups of users of a mobile network to communicate anonymously with respect to an adversarial party (i.e, other users, network managers, and so on). Each user can start a group communication, and his identity, as well as the identities of the other members of the group, are not revealed even if several other parties of the system collude. We consider two network settings and, for each of them, we propose an efficient and secure scheme.
