“…They are most important and most common attacks on reputation systems; they consist in having a malicious node behaving as if it were a larger number of nodes, i.e., by impersonating other nodes or simply by claiming false identities [31]. The attacker can then generate an arbitrary number of additional node identities within the network with the use of a single physical device [32]; to compromise the reputation system established within the network and gain the majority of influence over it, by performing illegal actions (in relation to the rules and laws established in the network). This can be prevented with a good matching engine and general cybersecurity mechanisms to ensure a good operation.…”

While online interactions and exchanges have grown exponentially over the past decade, most commercial infrastructures still operate through centralized protocols, and their success essentially depends on trust between different economic actors. Digital advances such as blockchain technology has led to a massive wave of Decentralized Ledger Technology (DLT ) initiatives, protocols and solutions. This advance makes it possible to implement trustless systems in the real world, which, combined with appropriate economic and participatory incentives, would foster the proper functioning and drive the adoption of a decentralized platform among different actors. This paper describes an alternative to current commercial structures and networks by introducing Lyzis Labs, which is is an incentive-driven and democratic protocol designed to support a decentralized online marketplace, based on blockchain technology. The proposal, Lyzis Marketplace, allows to connect two or more people in a decentralized and secure way without having to rely on a Trusted Third Party (TTP ) in order to perform physical asset exchanges while mainly providing transparent and fully protected data storage. This approach can potentially lead to the creation of a permissionless, efficient, secure and transparent business environment where each user can gain purchasing and decision-making power by supporting the collective welfare while following their personal interests during their various interactions on the network.

In mobile ad-hoc networks (MANET) security is a challenging issue because of its open nature, framework less property and portability of hubs. In designing new security techniques for mobile ad-hoc networks, one must think about the attacks and in addition the characteristics of that attacks that could be started against the mobile ad-hoc networks and existing detection systems. Mobile ad-hoc network is vulnerable to different kind of attacks. To provide safe data transmission the security must be provided against these attacks.

Mobile Ad hoc network comprises of many nodeswhich interact with each other through wireless links. It is infrastructure less in nature, due to which attackers can easily attack on the network from any side. There are many attacks which ruin the communication among the nodes of network. Among those attacks there is a Sybil attack that causes severe hazards to the network. Sybil attack is an attack which uses many identities at a time or one identity at a time. The identities used by Sybil attackers are either created by it or uses someone else's identity. This attack can decrease the trust of any legitimate node by using identity of that node and accumulate the secret or important data. Sybil attackers distribute secret data in other networks and it reduces the secrecy of network. In this way, Sybil attackers cause immeasurable loss to a network. In this research, Enhanced lightweight Sybil attack detection technique is discussed which is used to detect Sybil attack. Tool used for simulation is MATLAB.
