Abstract
Promoted by the advancements in the various wireless access technologies, modern mobile devices equipped with multiple network interfaces are rapidly becoming the norm, and this provides a driving force for the large-scale deployment of the Multipath Transmission Control Protocol (MPTCP) in the current and future Internet. However, the simultaneous use of multiple network paths for concurrent multipath data transmission can make MPTCP have a larger attack surface than the traditional single-path transport protocols, and this may be likely to pose a risk of MPTCP being much more susceptible to cyber attacks. In this paper, we present a measurement method to investigate the vulnerability and robustness of MPTCP under cyber attacks with incomplete network information, by considering the fact that most cyber attacks normally lack of real-time information with respect to various MPTCP attributes. We mathematically characterize cyber attacks with incomplete network information from the viewpoints of both the cyber attacker and the MPTCP communication system, and then we introduce a mixed attack strategy, by jointly considering the features of both the random attacks and the selective attacks, to evaluate the robustness of MPTCP.
Highlights
In the last few years, wireless communication technologies, such as wireless broadband technology, wireless Wi-Fi technology, Bluetooth technology and so on, have undergone unprecedented development [1], [2]
Multipath Transmission Control Protocol (MPTCP)-GRAPH MAPPING We focus on a steady-state MPTCP communication system and act with a series of assumptions: (i) there are two multi-homed end-hosts equipped with the same amount of network interfaces, (ii) each network interface has its own unique IP address, (iii) the two end-hosts are communicating with each other using multiple end-to-end independent transmission paths (MPTCP subflow), enabled by MPTCP, (iv) all the transmission paths within the MPTCP connection are available for data transmission, and (v) a cyber attacker can access partial network resources and obtain partial MPTCP paths’ quality of service (QoS)-related networking parameters
WORK With the promising feature of simultaneous transmission of data through multiple Transmission Control Protocol (TCP) connections, MPTCP is being considered as the transport technique of the popular choice for the modern multi-homed mobile devices, its multipathing paradigm may be likely to pose a risk of MPTCP being much more susceptible to cyber attacks, especially when the unlicensed wireless local area networks is used in multipath transmissions
Summary
In the last few years, wireless communication technologies, such as wireless broadband technology, wireless Wi-Fi technology, Bluetooth technology and so on, have undergone unprecedented development [1], [2]. The latest advancements in the wireless communication technologies provide a great driving force for the large-scale use of multi-homed mobile devices in the current and future Internet. Such multi-homed mobile devices (e.g., smartphones, netbooks, and portable computers) are commonly configured with several wireless network interfaces and multiple different IP addresses [3], [4]. They can simultaneously use their own network interfaces to establish multiple communication paths to access Internet, and. The network paths in multipath transmission can be managed (e.g., creation, removal, reconnection) by MPTCP according to their own network condition
