This paper presents an approach for resource allocation functionality with cluster aggregation (RAFCA) for securely transmitting surveillance videos in high-speed trains (HSTs). Each train wagon is assumed to be equipped with a surveillance camera, along with a mobile relay (MR) that communicates with the cellular base station (BS) on one hand and with the indoor devices inside the train on the other. The RAFCA approach is based on a permutation process of the video frames across multiple MRs, such that parts of the video captured by the camera of a given wagon are transmitted by the MRs of all other wagons. The probability of detection by an eavesdropper is calculated in this paper and shown to be negligible, which leads to the preservation of the privacy of the passengers. Moreover, the proposed approach is shown to have no or little impact on the quality of experience (QoE) of the transmitted videos, thus preventing quality degradation.
