Abstract: A wireless communications system may include a plurality of wireless communications devices (WCDs). A source WCD from among the plurality of WCDs may be configured to designate message data for at least one target WCD from among the plurality of WCDs, where the message data has a security restriction associated therewith. At least one intermediary WCD from among the plurality of WCDs may be configured to wirelessly receive the message data from the source WCD when in proximity thereto, and with restricted access to the message data based upon the security restriction. The at least one target WCD may be configured to wirelessly receive the message data from the at least one intermediary WCD when in proximity thereto and with less access restriction to the message data than the at least one intermediary WCD.
