“…Similary, Ring signatures [49] allow to sign on behalf of an ad hoc group of nodes without the help of a central coordinator. However, the location privacy provided by ring signatures is still an open problem [23]. Anonymous credential systems (e.g., Idemix [12]) allow mobile nodes to anonymously authenticate to third parties with the help of an online credential issuer.…”

In mobile networks, authentication is a required primitive of the majority of security protocols. However, an adversary can track the location of mobile nodes by monitoring pseudonyms used for authentication. A frequently proposed solution to protect location privacy suggests that mobile nodes collectively change their pseudonyms in regions called mix zones. Because this approach is costly, self-interested mobile nodes might decide not to cooperate and could thus jeopardize the achievable location privacy. In this paper, we analyze the non-cooperative behavior of mobile nodes with a game-theoretic model, where each player aims at maximizing its location privacy at a minimum cost. We first analyze the Nash equilibria in n-player complete information games. Because mobile nodes in a privacy-sensitive system do not know their opponents' payoffs, we then consider incomplete information games. We establish that symmetric Bayesian-Nash equilibria exist with simple threshold strategies in n-player games and derive the equilibrium strategies. By means of numerical results, we show that mobile nodes become selfish when the cost of changing pseudonym is small, whereas they cooperate more when the cost of changing pseudonym increases. Finally, we design a protocol -the PseudoGame protocol -based on the results of our analysis.

“…Therefore, the threshold signature scheme is necessary for secure message transmission in MANETs. A recent research on cluster-based MANETs has sought to address the privacy problem [6] and threshold signature schemes [7], but research on anonymous threshold signature schemes in cluster-based MANETs has been insufficient. This paper proposes a security system for ID-based anonymous cluster-based MANETs to protect the privacy of nodes.…”

Security supports are a significant factor in the design of security system in ad hoc networks. It is particularly important to protect the identities of individual nodes to avoid personal privacy concerns. In this paper, we propose a security system for ID-based anonymous cluster-based MANETs to protect the privacy of nodes. Moreover, we propose a threshold signature scheme without pairing computations, which diminishes the computation load on each node. To the best of our knowledge, our proposed security system is the first in which the pseudonym is combined with cluster-based mobile ad hoc networks (MANETs) without a trusted entity. According to our protocol analysis, our proposal satisfies most properties for an anonymous security system and effectively copes with dynamic environments with greater efficiency by using secret sharing schemes. Therefore, it could be usefully applied to preserve privacy in dynamic MANETs without a trusted entity, such as military battlefields, emergency areas, mobile marketplaces, and vehicular ad hoc networks (VANETs).

“…Such a work provides simulation data, like [5], but the shown results are only described in a superficial way, with no images. Other schemes based on threshold cryptography and ring signatures are surveyed in [2], [9] but the same situation is repeated.…”

A mobile ad hoc network (MANET) is a type of wireless network without any infrastructure, where nodes must adapt to the changing dynamic situations that result from their mobility. Because of the decentralization of nodes and the security needs of communications, management of MANETs must be self‐organized, which is a major research challenge. In order to cope with the intrinsic properties of MANETs, a new decentralized management system for MANETs called Self‐organizing Life Cycle Management (SLCM) is here fully described and evaluated. Regarding security, node authentication is the most critical component of access control in any network and, in particular, in MANETs. Broadcasting is also a fundamental data dissemination mechanism in these networks. Both aspects have received special attention when defining the proposed SLCM system. In particular, both a strong access control algorithm, based on the cryptographic paradigm of zero‐knowledge proofs, and a three‐step broadcast protocol are here defined. This work includes the performance evaluation of the scheme, and the obtained experimental results show that SLCM significantly improves both the quality and the security of life cycle management of self‐organized MANETs.
