The demand for using wireless paradigms for performing various information and communication operations has been exploded. The opportunistic networks is a special type of delay tolerant networks proposed to operate in an emergency manner to facilitate mobile connectivity between the nodes when there is no connectivity. These emergencies are caused either by human-made or natural disasters. Opportunistic Networks depend on mobile phones and other mobile devices that carry wireless technology. This paper is an attempt to expand the opportunistic network through the authentication nodes. We propose an NTRU algorithm for node authentication in opportunistic networks .NTRU algorithm is an asymmetric post-quantum cryptosystem. This algorithm is unbreakable and robust compared to RSA and ECC cryptosystem.

“…One way to preserve the confidentiality of messages is to encrypt them so that they can only be read by the intended parties. Encryption [3] in OppNets is a challenging oper-ation. Conventional encryption schemes [4] both symmetric and asymmetric techniques are resource-intensive and nodes in OppNet are usually resource-constrained.…”

This paper proposes a novel Secure Multi- Geocasting Spray And Flood technique for opportunistic networks called SMGSAF, which uses secret sharing and disjoint path routing to secure the privacy of messages. In multi-geocasting, routing aims to successfully deliver a given geomessage to all the nodes, or to as many as possible, located inside defined geographic areas within a given time interval. It is desired that as long as a message is outside its destination casts it cannot be read by intermediate nodes. Encryption is a proven way to ensure this but classical encryption techniques are not well suited for the opportunistic paradigm. Key distribution and scarcity of resources are the major challenges in this regard. Therefore we have used secret sharing and disjoint path routing to protect the privacy of messages. Simulation results show that the proposed SMGSAF protocol provides the intended security but at the expense of performance, that is within acceptable limits. Notably, the SMGSAF protocol outperforms unitary geocasting in terms of delivery probability. The proposed protocol is evaluated in terms of delivery probability, network overhead, and latency. Its performance has been compared to MGSAF and GSAF.

“…Route maintenance process is initiated during link failures or disconnections. MANETs' routing protocols may be categorized on the base of topology-based [1,13,18] and position-based [11,10,6,2]. Information transmits in different ways between these protocols over the network depend on many factors.To shrink the consequence of link breakage on the network service leads to enhance the routingperformance.…”

Reliable link between the nodes playsvital role during the transmission of data in the routing protocols of Mobile Adhoc Networks (MANETs). In this research paper, a routing protocol Link named Expiration Time based Routing Protocol (LETSRP)is proposed which uses Winternitz One-time Signature Scheme to checkthe authentication of transmitted data in the network. The packet sending node calculates maximum LET (MaxLET), minimum LET (MinLET) and average LET (AvgLET) using greedy algorithm in our proposed solution. The number of sent packets dependson the available bandwidth. Various steps in implementation are repeated until all the packets reach the destination node. Simulations are done with variable number of nodes between10-20 nodes with mobility setting from 10 m/s to 20 m/s.
