In an emergency situation, receiving prompt and organized help from nearby people is of critical importance. The growing use of online social networks (OSNs) in emergency situations is a clear indication of the natural applicability of online social networking technologies to emergency responses. Despite this intense interest, a number of fundamental limitations still exist, such as lack of conceptual models and limitations on group organization and cooperation. To address existing limitations, we propose Whistle + -a cooperation framework for OSN users which can 1) dynamically organize an emergency community with nearby eligible users who are distributed in heterogeneous online social networks, and 2) guarantee secure communication, unrestricted cooperation and resource sharing by leveraging the SocialVPN virtual network and the Jitsi communicator. To test the feasibility and applicability of Whistle + , we present a prototype implementation and demonstrate its applicability to an example use case.

Virtual private networking (VPN) has become an increasingly important component of a collaboration environment because it ensures private, authenticated communication among participants, using existing collaboration tools, where users are distributed across multiple institutions and can be mobile. The majority of current VPN solutions are based on a centralized VPN model, where all IP traffic is tunneled through a VPN gateway. Nonetheless, there are several use case scenarios that require a model where end-to-end VPN links are tunneled upon existing Internet infrastructure in a peer-to-peer (P2P) fashion, removing the bottleneck of a centralized VPN gateway. We propose a novel virtual network -TinCan -based on peerto-peer private network tunnels. It reuses existing standards and implementations of services for discovery notification (XMPP), reflection (STUN) and relaying (TURN), facilitating configuration. In this approach, trust relationships maintained by centralized (or federated) services are automatically mapped to TinCan links. In one use scenario, TinCan allows unstructured P2P overlays connecting trusted end-user devices -while only requiring VPN software on user devices and leveraging online social network (OSN) infrastructure already widely deployed. This paper describes the architecture and design of TinCan and presents an experimental evaluation of a prototype supporting Windows, Linux, and Android mobile devices. Results quantify the overhead introduced by the network virtualization layer, and the resource requirements imposed on services needed to bootstrap TinCan links.

“…Figure 2 illustrates VPN architecture. There are four tunneling protocols used to establish VPNs, and three are extensions of the Point-to-Point Protocol (PPP) [5,6,10,11]: 1) Point-to-Point Tunneling Protocol (PPTP). 2) Layer 2 Forwarding (L2F).…”

“…In addition, Access control and intrusion detection [3,4] are not helpful against compromising of the authentication module. If a password is weak and has been compromised, access control and intrusion detection cannot prevent the loss or corruption of information that the compromised user was authorized to access, and also it is not helpful when the intruder uses the system and software bugs to compromise the integrity, confidentiality, or availability of resources [5,6].…”

A Virtual Private Network (VPN) allows the provisioning of private network services for an organization over a public network such as the Internet. In other words a VPN can transform the characteristics of a public which may be non-secure network into those of a private secure network through using encrypted tunnels. This work customized a standard VPN to a newly one called EEVPN (Effective Extensive VPN). It transmits a small data size in through a web based system in a reasonable time without affecting the security level. The proposed EEVPN is more effective where it takes small data transmission time with achieving high level of security. Also, the proposed EEVPN is more extensive because it is not built for a specific environment.
