Secure sensor data transmission in 5G networks using pseudorandom number generators

Abstract

Future 5G networks face the challenge of supporting the global communications among the millions
of devices making up the Internet-of-Things. Traditional 4G mobile devices have a high computational
power, so applications based on the transmission of sensor data (accelerometers, GPS,
etc.) may apply heavy end-to-end securing solutions. However, new 5G mobile components usually
present reduced capabilities and a low clock speed. Therefore, new security solutions for sensor data
transmission in streaming have to be developed. In this paper, it is described a light cryptography
technology to secure sensor data during radio transmission in 5G networks. The proposed solution
is based on pseudorandom number generators, which are specifically designed to fulfill the requirements
of 5G systems. A simulation scenario and a first real deployment are developed in order to
evaluate the performance of the contribution.
