This paper addresses a specific approach to resolving the problem of intrusion detection against distributed denial of service (DDoS) attacks in mobile ad hoc networks (MANET). The main function of an intrusion detection system (IDS) is to inspect the network for malicious activities, policy violations and security loopholes integrity, and to generate the appropriate reports. Network forensics ...

Digital signatures allow us to produce documents whose integrity and authenticity, as we generated them, is verifiable by anybody who has access to our public key. Furthermore, we cannot repudiate those documents as something we never saw, let alone signed, since nobody else but us could access our private key. In this paper we show how the previous statement can be proved wrong when carefully ...

In the biclique attack, a shorter biclique usually results in less data complexity, but at the expense of more computational complexity. The early abort technique can be used in partial matching part of the biclique attack in order to slightly reduce the computations. In this paper, we make use of this technique, but instead of slight improvement in the computational complexity, we keep the amo...

Defense strategies have been well studied to combat Byzantine attacks that aim disrupt cooperative spectrum sensing by sending falsified versions of data a fusion center. However, existing studies usually assume network or attackers as passive entities, e.g., assuming the prior knowledge is known fixed. In practice, can actively adopt arbitrary behaviors and avoid pre-assumed patterns assumptio...

Cooperative Spectrum Sensing (CSS) is an effective approach to overcome the impact of multi-path fading and shadowing issues. The reliability of CSS can be severely degraded under Byzantine attack, which may be caused by either malfunctioning sensing terminals or malicious nodes. Almost, the previous studies have not analyzed and considered the attack in their models. The present study introduc...

Abstract— A Sybil attacker is a malicious node which creates several false identities to itself. This attack is extremely harmfull to any voting or cooperation-based system, like a MANET. MANETs (Mobile Ad hoc Networks) are dynamically establiched, cooperation-based wireless networks, deployed without any infrastructure or centralized administration. Due to their dynamic environment, MANETs are...

Wireless sensors networks (WSNs) consist of a large number of tiny, spatially distributed, and autonomous devices, called sensor nodes. The latter are equipped with sensing, computation, and wireless communications capabilities, and have very limited resources. Wireless sensor networks have been widely used in remote areas, military scenarios, sensing motion applications, agriculture solutions ...

To support Evolved Packet System (EPS) in the Long Term Evolution (LTE) networks, the 3rd Generation Partnership Project (3GPP) has proposed an authentication and key agreement (AKA) protocol, named EPS-AKA, which has become an emerging standard for fourth-generation (4G) wireless communications. However, due to the requirement of backward compatibility, EPS-AKA inevitably inherits some defects...

Certificateless cryptography involves a Key Generation Center (KGC) which issues a partial key to a user and the user also independently generates an additional public/secret key pair in such a way that the KGC who knows only the partial key but not the additional secret key is not able to do any cryptographic operation on behalf of the user; and a third party who replaces the public/secret key...

Identity Based Cryptography (IBC) is well known method in the field of security, however it has an inherent drawback of Key Escrow under which central key generation center is a sole issuing authority of private key and thus could misuse it. Our survey finds numerous solutions of key escrow; out of them secure key issuing protocol (SKIP) is most prominent. However, there are scopes for improvin...
