Abstract - Wireless Sensor Networks (WSNs) have been applied in variety of industrial, medical and military applications. There are many routing protocols proposed for WSNs to deal with challenges such as energy depletion and latency of data transmission from nodes to base station. Recently, researchers have focused on Chain-based protocols. CCBRP (Chain-Chain Based Routing Protocol) tries to decrease both energy consumption and latency time, but it has some challenges such as randomness in choosing of chain leaders and not supporting of any fault tolerant mechanism. Due to energy depletion and mobility of nodes, nodes failure is unavoidable in WSNs. However, few protocols considered fault tolerant mechanisms while fault tolerant routing is a critical task in WSNs in dynamic environments to improve network reliability. In this paper, we aim to employ fault tolerant mechanism in CCBRP. We propose an approach to prevent early failures of chains in wireless sensor grid networks. The approach is modeled by Markov chain and the results show more reliability for our approach than simple CCBRP. |

Abstract - Network administrator performs port scanning for the purpose of network monitoring and troubleshooting on the other hand this facility become vulnerability when attacker performs port scanning for probing networks, searching for vulnerabilities and then infiltrate IT assets. It is often a primarily tactic that is adopted by attacker prior to launching a targeted cyber-attack. Moreover in recent times, port scanning techniques become highly distributed, composite, hybrid, and stealthy, therefore almost all current detection techniques are unfeasible. Stealth is considered to be a type of port scan which is undetected by available auditing tools such as firewall, routes, filters etc. A stealth port scan method does not produce any TCP sessions; hence, none of these scans should appear in any of the application logs. Therefore, it is of vital importance to research and adopt methods for the detection and attribution of stealth port scanning attack. In this work a network forensic architecture for detection and analysis of stealth port Scanning attack is proposed. It consist of two main modules, a capturing module that captures fine grained evidences from the network traffic and an analysis module that classifies each packet based on the predefined signature. A proof of concept prototype is implemented which utilize, operational network traffic data injected with crafted scans to test the system. It is reported that the proposed system correctly identifies crafted scans injected into real traffic. |

Abstract - Digital signatures that are used to achieve the integrity along with the authentication could be classified into various types. PKI based, ID based, certificate based and certificateless digital signatures are the most important types. Regarding advantages of certificate-based signatures (CBS), we want to propose a CBS scheme by means of employing elliptic curve discrete logarithm problem (ECDLP).The proposed schemes security is proven under the elliptic curve discrete logarithm assumption in the random oracle model. Results of comparing our scheme with existing pairing-free certificate-based signature schemes, shows that ours has much lower computational cost. |

Abstract - In this article we developed a new block encryption algorithm based on network RFWKIDEA8-1 using of the transformations of the encryption algorithm AES, which is called AES- RFWKIDEA8-1. The blocks length of this encryption algorithm is 256 bits; the numbers of rounds are 10, 12 and 14. The advantages of the encryption algorithm AES- RFWKIDEA8-1 are that, when encryption and decryption process used the same algorithm. In addition, the AES-RFWKIDEA8-1 encryption algorithm encrypts faster than AES. |

Abstract - Degrading or declining network performance in an installed computer network system is the most undesirable condition. There are several factors contribute to the decline of network performance, which their indications can be observed from quality changes in Quality of Service (QoS) parameters measurement result. This research proposes recommendations in improving network performance towards the changes of QoS parameters quality. |
