Abstract

MultiPath TCP (MPTCP) is a recent TCP extension that enables hosts to send the data belonging to one connection over multiple paths. It is already deployed for various use cases, notably on smartphones. In parallel with this, there is a growing deployment of encryption and authentication techniques to counter various forms of attacks. Tcpcrypt and the Transport Layer Security (TLS) are some of these security solutions. In this paper, we propose MPTCPsec, a MultiPath TCP extension that closely integrates authentication and encryption inside the protocol and shows how it counters several types of attacks.

Abstract

International audience; Universal Mobile Telecommunications System) is a 3 rd generation communication system that uses WCDMA access technology (Wideband Code Division Multiple Access) to obtain high data rates and ensure better quality of multimedia communications. MPEG-4 (Moving Picture Experts Group) is widely used for video transmission services on any network because of the good quality of service it provides. UMTS has several radio channels for transporting data to and from these mobile users. This article focuses on a comparative study between the DCH channel (Dedicated Transport Channel) and the HS-DSCH channel (High Speed Downlink Shared Channel) by analyzing the qualities as packet loss, bit rate, throughput, transmission delay, availability, jitter, etc. offered by each of them in order to determine the suitable video transmission
