WIRELESS NETWORK SECURITY (CS6526/FALL 2014) ASSIGNMENT # 2 NAME: VIDYA PANGA NET ID: KS9877 1. What are the security requirements and challenges of MANETs? Answer: MANETs (Mobile ad-hoc network) is defined as autonomous collection of wireless mobile nodes that are self-configure to construct a network that can communicate over relatively bandwidth constrained wireless links. In MANETs the security depends on the several parameters are as follows: Authentication: It enables the mobile nodes to ensure the identity of the nodes they are communicating with. With this it provides the secure communication among the nodes. It also helps in identifying the false identity of nodes. This avoids the unauthorized nodes to gain access of the other nodes. Confidentiality: It prevents the access to the data for unauthorized users or nodes when two authorized nodes are communicating .Since MANETs use the open medium, all users present within the transmission range will have access to the data. The data can be kept confidentially by performing encryption on it. Integrity: It prevents the data from being modified or unchanged by the unauthorized users while transmitting the data. It never discloses the data to the unauthorized users. With this it provides the users a secure communication without any modifications in the data. Non repudiation: It ensures that nodes in the MANETs should not deny their responsibility of actions while sending and receiving the data packets. With the help of
