Anonymous Authentication Against Man-In-The-Middle Attack

Evolving enterprise in application and data with flexible and scalable infrastructure in cloud services could improve efficiency and productivity of a business operation. Cloud services also offer resource sharing, data storage and application platform as on-demand services that could reduce the operational expenditure. Nevertheless, increasing usage and accessibility to the cloud services require strong security control to preserve user’s privacy and data integrity due to network communication vulnerabilities. There are many possible attacks that could cause security breach and abuse the user’s identity, leading to illegal access to the server. Man-inthe-middle attack is one of the attacks that can intercept communication between users and collect all users’ information. The attacker can misuse the information and act as a legal user to gain access to the system. It is a big challenge to preserve user’s privacy and provide protection from malicious attack. This paper proposes anonymous authentication scheme to preserve user’s privacy and provide protection to such possible attacks. The proposed scheme also provides secure mutual authentication, anonymity, session key establishment and non-dependency with the third party. The proposed scheme uses password-based authentication as an authentication method with anonymity feature to preserve user’s privacy. Experiment was conducted to test and validate the proposed scheme with man-in-the-middle attack. The result of the experiment shows that the proposed scheme is able to provide the privacy to mitigate and successfully preserve the user’s identity from the attack

Performance analysis of random-based mobility models in MANET routing protocol.

With current advances in technology, wireless networks are increasing in popularity. Wireless networks allow users the freedom to travel from one location to another without interruption of their computing services. Ad hoc networks is one of the subset of wireless network that dynamically forming a temporary network without using any existing network infrastructure or centralized administration. Therefore, it is required a good routing protocol in order to established the connection between the nodes since the mobile node can change their topology frequently. In the routing protocol, the movement of the mobile node is one of the important characteristics because it can effects the performance of the ad hoc network protocol. In this research, we have studied the effect of the different mobile node movement pattern in random-based mobility model group (Random Waypoint Mobility Model, Random Walk Mobility Model and Random Direction Mobility Model) on the performance of Ad hoc On-demand Distance Vector (AODV). The performance analysis was conducted by using the discrete-event simulator, OMNeT++. The simulator was used to simulate the mobility environment and the Open System Interconnections (OSI) layers utilized in wireless simulation. The simulation results illustrate the performance of the routing protocol varies across different performance metrics
