Privacy-Preserving Adaptive Multi-channel Communications under Timing Constraints

Currently, privacy leakage has become a great concern when a web-based application is applied. The threats deriving from communications are generally caused by implementing lower-level security protocols. However, using a higher-level privacy protection approach is often restricted by the efficiency requirements, since an enhanced security level needs a longer execution time than the approach offering a lower-level privacy protection. This work focuses on this issue and proposes a new approach that provides an adaptive multi-channel communications solution. The proposed approach is called Dynamic Multi-Channel Communications (DMC2) model, which is designed to dynamically determine the transport layer protocols in terms of the timing constraints. We consider four contemporary deployed protocol types the optional channels and our method can produce optimal solutions to maximizing the privacy level. Our experimental evaluations have examined the performance of DMC2, which demonstrates its privacy protection capability and the adaptability.
