DiscoverFriends: Secure Social Network Communication in Mobile Ad Hoc Networks
It addresses privacy and security for users in mobile ad hoc networks by enabling serverless communication, though it is incremental as it builds on existing cryptographic techniques.
The paper tackles secure group communication among friends in mobile ad hoc networks by developing DiscoverFriends, which bypasses social networking servers and achieves secure identification and authentication using Bloom filters and hybrid encryption, with evaluation showing it implements the first Android multi-hop WiFi direct protocol using IPv6.
This paper presents a secure communication application called DiscoverFriends. Its purpose is to securely communicate to a group of online friends while bypassing their respective social networking servers under a mobile ad hoc network environment. DiscoverFriends leverages Bloom filters and a hybrid encryption technique with a self-organized public-key management scheme to securely identify friends and provide authentication. Additionally, DiscoverFriends enables anonymous location check-ins by utilizing a new cryptographic primitive called Function Secret Sharing. Finally, to the best of our knowledge, DiscoverFriends implements and evaluates the first Android multi-hop WiFi direct protocol using IPv6.
