Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on the concept of gossip. Despite its important contribution, this algorithm has deficiencies especially with high number of nodes that leads to high execution time and low accuracy in the results. In this paper, a grouped Gossip based Reputation Aggregation (GGRA) algorithm is proposed. In GGRA, Gossip Trust is executed in each group between group members and between groups instead of executing in the whole network. Due to the reduction in the number of nodes and using strongly connected graph instead of a weakly one, gossip algorithm in GGRA is executed quickly. With grouping, not only reputation aggregation is expected to be more scalable, but also because of the decrement in the number of errors of the gossiped communication, the results get more accurate. The evaluation of the proposed algorithm and its comparison with Gossip Trust confirms the expected results.","PeriodicalId":436674,"journal":{"name":"ISC Int. J. Inf.

Providing security mechanisms, and especially a suitable access control mechanism, which enforces the defined security policy is a necessary requirement in VOs. Since VO is a complex environment with the huge number of users and resources, traditional access control models cannot satisfy VOs security requirements. Most of the current proposals are basically based on the attributes of users and resources. In this paper, we suggest using a combination of the semantic based access control (SBAC) model, and the attribute based access control (ABAC) model with the shared ontology of subjects' attributes in VOs. In this model, each participating organization makes its access control decisions according to an enhanced model of the ABAC model. However, access decision in the VO is made in more abstract level through an enhanced model of theSBACmodel. Using the ontology of users and resources in this model facilitates access control in large scale VOs with numerous organizations. By the combination ofSBACand ABAC, we attain their benefits and eliminate their shortcomings. In order to show the applicability of the proposed model, an access control system, based on the proposed model, has been implemented in Java using available APIs, including Sun's XACML API, Jena, Pellet, and Protege.","PeriodicalId":436674,"journal":{"name":"ISC Int.

Movaghar","doi":"10.22042/ISECURE.2015.6.2.7","DOIUrl":"https://doi.org/10.22042/ISECURE.2015.6.2.7","url":null,"abstract":"Mobile ad-hoc networks (MANETs) have no fixed infrastructure, so all network operations such as routing and packet forwarding are done by the nodes themselves. However, almost all common existing routing protocols basically focus on performance measures regardless of security issues. Since these protocols consider all nodes to be trustworthy, they are prone to serious security threats. Wormhole attack is a kind of such threats against routing processes which is particularly a challenging problem to detect and prevent in MANETs. In this paper, a two-phase detection scheme is proposed to detect and prevent wormhole attacks. First phase checks whether a wormhole tunnel exists on the selected path or not. If there is such a tunnel, the second phase is applied to confirm the existence of the wormhole attack, and locate a malicious node. The proposed detection scheme can appropriately detect all types of this kind of attacks such as in-band and out-of-band ones in different modes such as hidden or exposed, without any need of special hardware or time synchronization. In order to evaluate the performance of the proposed scheme, some various scenarios are simulated in the NS-2 simulator, and different measures are assessed. The results obtained from simulating the proposed scheme and other benchmarks indicate that in most criteria considered in this paper, the proposed scheme outperforms the proposed methods in prior works.","PeriodicalId":436674,"journal":{"name":"ISC Int.
