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

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.
