The emerging Internet-of-Things (IoT) are vulnerable to Sybil attacks where attackers can
manipulate fake identities or abuse pseudoidentities to compromise the effectiveness of the …

In the recent era, the security issues affecting the future Internet‐of‐Things (IoT) standards
has fascinated noteworthy consideration from numerous research communities. In this view …

Cryptographic algorithms have been used not only to create robust ciphertexts but also to
generate cryptograms that, contrary to the classic goal of cryptography, are meant to be …

The problem of malicious activities in online social networks, such as Sybil attacks and
malevolent use of fake identities, can severely affect the social activities in which users …

Abstract Today, Wireless Sensor Networks are widely employed in various applications
including military, environment, medical and urban applications. Thus, security …

Being a volunteer-run, distributed anonymity network, Tor is vulnerable to Sybil attacks. Little
is known about real-world Sybils in the Tor network, and we lack practical tools and methods …

Proof-of-work (PoW) is an algorithmic tool used to secure networks by imposing a
computational cost on participating devices. Unfortunately, traditional PoW schemes require …

In this paper we have a close look at the Sybil attack and advances in defending against it,
with particular emphasis on the recent work. We identify three major veins of literature work …

Sybil attack is a well-known attack against wireless sensor networks (WSNs) in which a
malicious node attempts to propagate multiple identities. This attack is able to affect routing …

Wireless networks are vulnerable to Sybil attacks, in which a malicious node poses as many
identities in order to gain disproportionate influence. Many defenses based on spatial …
