“…Distributed communication is important to be achieved for MANET-based sensing and scrutiny applications. The communication will be effective only if all the nodes follow a trustworthy behaviour [1][2][3]. The MANETs is established in unconstrained environments with no centralized controlling authority, where the node compromising and attacks happen at higher probability.…”

In mobile ad hoc networks (MANETs), the reliability of nodes, quality of data and access control cannot be achieved successfully for various network functionalities through traditional cryptographic security, which makes MANET vulnerable to illegitimate node behaviour changes. These node misbehaviours, referred as soft security threats, need to be detected and prevented in order to protect against the accumulation of false measurements with selfish and malicious intentions. Trust has been employed as a powerful tool to handle the soft security threats and to provide security among uncertain and dynamic nodes effectively in MANET. Therefore, it is of great importance that efficient trust management mechanisms should be developed in a public key infrastructure (PKI), in order to verify the identities on the ad hoc networks for reliable and secure group communication. However, the independent nature of nodes and the computational complexities make the trust management a challenging one in MANET. In this paper, we present an efficient distributed trust computation and misbehaviour verification method with Bayesian and Evidence theorem, on hexagonally clustered MANET. Besides, a secured PKI system is designed in the paper by applying the proposed trust management scheme in terms of certificate revocation, which is an important functionality of PKI cryptosystem. The uncertainty impacts the node's anticipation of neighbour's behaviour and decisions during communication; we include uncertainty in the trust management system. An efficient method to reduce the uncertainty is to exploit the mobility characteristics of MANET that accelerates the trust convergence. The simulation results reveal a better performance against adversaries in creating considerable untrustworthy transactions with a mobility-aware cluster guarantee. Moreover, the proposed trust application shows its betterment in the revocation process in terms of revocation rate and time. Thus, the proposed scheme provides an effective security solution that incorporates the optimistic features of trust mechanisms and hierarchical Voronoi clustering.

“…It is a human cognitive function that spurs social interactions. Recently, many researchers are working to imitate the way human assess trust, as a channel for socializing into our new security concepts for ubiquitous computing [4][5][6][7][8][9][10][11][12][13]. There emphasizes is on the computational capabilities, with less concern for systematically designed trust infrastructure resulting in ambiguous requirements for access control in ubiquitous environment.…”

To secure computing in pervasive environment, an adaptive trust and recommendation based access control model (based on human notion of trust) is proposed. The proposed model provides support to calculate direct as well as indirect trust based on recommendations. It handles situations (by itself) both in which the requesting entity has a past experience with the service and a stranger entity requesting to access the service without any past interaction with the service. It encompasses the ability to reason human cognitive behavior and has the capability to adjust in accordance with behavioral pattern changes. X-bar control chart is used to handle malicious recommendation. The defense mechanisms incorporated by proposed model against attacks such as bad mouthing attack, oscillating behavior attack and conflicting behavior attack are also demonstrated.

Abstract. Role Based Access Control (RBAC) has been introduced in an effort to facilitate authorization in database systems. It introduces roles as a new layer in between users and permissions. This not only provides a well maintained access granting mechanism, but also alleviates the burden to manage multiple users. While providing comprehensive access control, current RBAC models and systems do not take into consideration the possible risks that can be incurred with role misuse. In distributed environments a large number of users are a very common case, and a considerable number of them are first time users. This fact magnifies the need to measure risk before and after granting an access. We investigate the means of managing risks in RBAC employed distributed environments and introduce a probability based novel risk model. Based on each role, we use information about user credentials, current user queries, role history log and expected utility to calculate the overall risk. By executing data mining on query logs, our scheme generates normal query clusters. It then assigns different risk levels to individual queries, depending on how far they are from the normal clusters. We employ three types of granularity to represent queries in our architecture. We present experimental results on real data sets and compare the performances of the three granularity levels.
