  An infrastructure network is a self-organizing network which uses Access
Point (AP) of wireless links that connecting one node with another. These nodes
can communicate without using ad hoc, instead these nodes form an arbitrary
topology (BSS/ESS) in which these nodes play the role of routers. Though the
efficiency of Infrastructure networks is high, they are highly vulnerable to
security attacks. Detecting/Preventing these attacks over the network is highly
challenging task. Many solutions are proposed to provide authentication,
confidentiality, availability, secure routing and intrusion avoidance in
infrastructure networks. Providing security in such dynamically changing
networks is a hard task. Characteristic of infrastructure network should also
be taken into consideration in order to design efficient solutions. In this
study, we focus on efficiently increasing the flow transmission confidentiality
in infrastructure networks based on multi-path routing. In order to increase
confidentiality of transmitted data, we take advantage of the existence of
multiple paths between nodes in an infrastructure network with the help of
Access Point. In this approach the original data is split into package and are
forwarded through access point. The encrypted packets are then forwarded in
different disjoint paths that exist between sender and receiver. Even if an
attacker succeeds to obtain one or more transmitted packets, the probability of
reconstructing the original message is very low.
