Dear all, 

We have submitted the paper „A Secure Self-Authenticable Data Transfer Protocol for Wireless Medical Sensor Networks“

Abstract: Development of IoT (The Internet of Things) introduces many new challenges. As IoT devices are getting smaller and smaller the problems of so called “constrained devices” arise. The traditional Internet protocols are not very well suited for constrained devices comprising localized network nodes with tens devices primarily communicating with each other (e. g. various sensors in Body Area Network communicating with each other). These devices have very limited memory, processing and power resources so traditional security protocols and architectures doesn’t fit well also. To address these challenges the fog computing paradigm is used in which all constrained devices or “End Nodes” primarily communicate only with less constrained “Fog Node” device, which collects all data, processes it and communicates with the outside world. A new lightweight secure self-authenticable transfer protocol (SSATP) for communications between “Fog End” devices and “Fog Nodes” is presented in this paper. The primary target of the proposed protocol is to use it as a secure transport for CoAP in place of UDP and DTLS which are traditional choices in this scenario. SSATP uses modified header fields of standard UDP packets to transfer additional protocol handling and data flow management information as well as user data authentication information. The optional redundant data may be used to provide increased resistance to data losses when protocol is used in unreliable networks. The results of experiments presented in this paper show that SSATP is better choice than UDP with DTLS in the cases where CoAP block transfer mode is used and/or in lossy networks.

This paper is still under evaluation.
