“…The vulnerabilities and attacks found in the network layer can be divided into blockchain-or P2P-specific issues (for P2P, see, for example, Schäfer et al [146]) and general network issues. The blockchain-specific and network-related items can be applied to SSI.…”

Self-sovereign identity (SSI) is a digital identity management model managed in a decentralized manner. It allows identity owners to manage and store their digital identities in a software wallet, for example, on a smartphone, without relying on centralized providers. This approach tries to enhance the security and privacy of digital identities and, thereby, their owners. With the new eIDAS regulation, elements of SSI, such as the wallet, are being pushed onto the market. However, since the model is relatively new, the security threats are still not fully known. This is shown by a brief security analysis of selected existing SSI wallets. In order to get a picture of the known threats, we systematically analyze and categorize related work in the field of SSI and elements applied by SSI. We then evaluate their application to current SSI systems and identify future work.

The Peer-to-Peer network has been widely used to share large files anonymously. Because of its open nature, nodes can join and leave Peer-to-Peer networks freely. But there are few limited methods to ensure their trust. Malicious nodes can expose great security threats to Peer-to-Peer networks such as spreading inauthentic data and viruses. But handling all the malicious nodes in the same way causes wastes of the network. In this paper, we first introduce the existing ways of handling malicious nodes in the Peerto-Peer network and then present a better approach dealing with malicious nodes which has a better performance than before.

“…Open and anonymous nature of P2P applications lead to complete lack of accountability of the contents that a peer may put in the network. The malicious peers often use these networks to do content poisoning and to distribute harmful programs such as Trojan Horses and viruses [12]. Distributed reputation based trust management systems have been proposed by researchers to provide protection against malicious content distribution [1].…”

File sharing peer-to-peer networks have become quite popular of late as a new paradigm for information exchange among large number of users in the Internet. However, these networks suffer from several problems such as fake content distribution, free riding, whitewashing, poor search scalability, lack of a robust trust model and absence of user privacy protection mechanism. In this paper, a secure and efficient searching scheme for peer-to-peer networks has been proposed that utilizes topology adaptation by constructing an overlay of trusted peers where the neighbors are selected based on their trust ratings and content similarities. While increasing the search efficiency by intelligently exploiting the formation of semantic community structures among the trustworthy peers, the scheme provides a highly reliable module for protecting the privacy of the users and data in the network. Simulation results have demonstrated that the proposed scheme provides efficient searching to good peers while penalizing the malicious peers by increasing their search times.
