The architecture and characteristic of Wireless Mesh networks (WMN), as well as the significance of Intrusion Detection System (IDS) in its application were investigated Based on the embedded analyzing of IDS technologies in Ad hoc network and WLAN (Wireless Local Area Network), combined with the security requirements in WMN itself, it is concluded that both the architecture of distributed and cooperative IDS in Ad hoc network and distributed IDS in WLAN can not be applied directly in WMN. A new architecture of asymmetric distributed and cooperative IDS for WMN based on the application of agent was proposed in the paper. This new architecture of IDS in WMN was then simulated by the attack detection of IEEE 802.11 MAC selfish behavior in NS2, using the IDS selfish behavior attack detection model ground on the judgment mechanism of double mode, which was also brought forward. The result of the simulation shows that the given new architecture of asymmetric distributed and cooperative IDS and the IDS selfish behavior attack detection model fitted WMN well.

In recent years, Grid systems and Peer to Peer networks are the most used solutions to achieve the same goal: sharing resources and services in heterogeneous, dynamic, distributed environments. Grid systems have well defined middleware, able to assure trust among participants, but they are not totally scalable and they have low fault tolerance. On the other hand, with their decentralized model, P2P systems are more scalable and fault tolerant than Grid systems, but they do not have concrete solutions for issues related to security or credential management. Many studies have proposed hybrid approaches that try to conjugate the advantages of the two models. This paper proposes an architecture that integrates the P2P interaction model in Grid environments, so as to build an open cooperative model wherein Grid entities are composed in a decentralized way. In particular, this paper focuses on a QoS aware discovery algorithm for P2P Grid systems, analyzing protocols and explaining techniques used to improve its performance. © 2007 IEEE.

P2P file-sharing poses a number of problems for system administrators including unpredictable network usage, increased vulnerability to security threats and the danger of legal action. Due to these problems, many businesses take measures to restrict the use of P2P software, but how successful have these measures been? This paper analyzes the degree to which business networks have been penetrated by P2P applications and shows that despite the risks, business networks participate significantly in P2P file-sharing systems. Furthermore, we find that participation is greatest amongst small businesses and that viral media has a significant effect on the participation of large businesses. © 2007 IEEE.

The recent years have seen an increase in identity fraud and accessing online services when communication devices such as computers, mobile phones and card based credentials (e.g. credit cards) are involved. This has prompted most governments and business organizations to change the way they do business and manage the user's identity information. However Internet users are vulnerable to identity fraud, which is on the increase and costing the global economy excessive amounts. With the advent of wireless technologies, peer-to-peer communication, GSM networks, it is becoming more challenging to build systems to authenticate users more efficiently. Traditional methods of authenticating a user with passwords and PIN numbers only are slowly proving ineffective since these credentials are easy to guess and steal. This paper proposes a distributed multimodal authentication system as a solution for managing digital identity information on most wireless networks. The proposed system uses artificial intelligence methods and biometrics to improve the security and privacy of users and service providers in a transparent, reliable and efficient way. The system is implemented using a technique of information fusion to combine the user's credentials for optimum recognition and authentication. © 2007 IEEE.

In this paper, we present a simple, automated response model that utilizes the Shewhart's control charts based-on network connection to aid in handling DDoS attacks. This model is designed to prevent incoming traffic from exceeding a given threshold, while allowing as much incoming, legitimate traffic as possible. In addition, this model focuses on requiring less demanding modifications to external routers and networks than other published distributed response models that impact the effect of DDoS attacks. The experimental results show the effectiveness of our scheme in early mitigating DDoS attacks. Copyright 2007 ACM.

Traditional security model, where the identity of all possible requesting subjects must be pre-registered in advance, is not suitable for the distributed applications with strong real-time requirements, especially recently popular P2P networks and Grid computing. A promising approach is represented by automated trust negotiation, which establishes trust between strangers through the exchange of digital credentials and the use of access control policies. An automated trust negotiation strategy needs to be adopted to establish trust between two parties based on their disclosure policies. Previously proposed negotiation strategies may fail when in fact success is possible, disclose irrelevant credentials, or have high communication or computational complexity. In this paper, we model the policies participating trust negotiation as Negotiation Petri Net and propose a trust negotiation Strategy based on Negotiation Petri Net (SNPN) by combining the characteristics of Negotiation Petri Net architecture with the behaviors of auto trust negotiation. We prove that SNPN is efficient with O(n) communication complexity and O(nm) computational complexity including Negotiation Petri Net building process and the negotiation process in the worst case, where n is the number of credentials and m is the size of the credential disclosure policies. Meanwhile SNPN is complete and makes sure that no irrelevant credentials will be disclosed during negotiations. Copyright 200X ACM

Grid computing has been cited as one of the potential technologies that can offer mammoth computing power in the future. The greatness of grid technology lies in the efficient harnessing of idle resources of the distributed environment, leading to better resource utilization. security is one of the key aspects of the grid technology. Secure group communication in the grid is a promising area with a broad scope for myriad of applications. Of late, it has been receiving good attention from the researchers. Sincere efforts have been made on proposing a highly secure, distributed, scalable and computationally efficient model for group communication in the grid environment. The proposed G-LeaSel multicast security model caters to the needs of the collaborative grid applications. The model is an adapted version of LeaSel model, already proposed and proven for wired and mobile networks.

distributed agreement protocols among a group of application processes are often built upon atomic multicast message delivery guarantees. Issues arise however when agreement protocols are realized in Information Assurance (IA) settings where extreme failure behaviors such as send-omission of processes and message timeliness violations are likely. The issues are compounded by security weaknesses in the communication software that make it easier for intruders to stage attacks. These issues impact the design of agreement protocols, which have hitherto assumed only benign failures such as process crash and network message loss/delay. In this paper, we revisit the distributed agreement problem, taking into account the IA dimension as well. Our study reveals the need for a secure centralized entity to realize the group decision-making and state coordination functions. Two functions are studied: dynamic group membership management to exclude non-cooperating members from the group and security-reinforced communications to enforce mutual anonymity of members. Our paper walks through a state-machine based realization of distributed agreements using secure atomic multicast protocol as an underlying communication substrate. The use of our approach in IA applications is also described.

Secure and reliable group communication is an important aspect of security in distributed ad hoc sensor networks. Most sensors are built to be inexpensive, low power devices and consequently have limited computational and communication resources. Constraints in resources make most conventional security protocols, such as Diffie-Hellman key exchange impractical. This work adapts existing work on tree-based group key agreement that combines key trees with Diffie-Hellman key exchange, by replacing expensive public key operations with relatively cheaper symmetric key operations. The modular exponentiations in Z n * used in Diffle-Hellman key exchange are replaced by polynomial evaluations in GF(2 m ) Galois fields, thereby reducing the code space and time complexity requirements for the protocols substantially. This makes the protocol adaptable for use on resource-constrained sensor networks. We also focus on secure and efficient group key management in the case of group mutation. Our group key management scheme will set up a per-session shared secret key among the group members when new members join or existing members leave the group. We also discuss a performance analysis of our scheme wherein we show that our protocol is efficient in terms of computational and memory requirements.
