Cryptography Applied to the Internet of Things

Abstract:

Concepts and technologies that have made it possible for devices to interconnect to real-world objects, have existed for some time. The Internet of things can be defined as a pervasive and ubiquitous network that allows the monitoring and control of the physical environment by collecting, processing and analyzing data generated by sensors or smart objects. As the number of devices connect to the Internet increases, it is necessary to provide a safe and reliable operation of such devices. This paper emphasizes the use of cryptographic algorithms that can be implemented in devices that can connect to the internet of things, in order to provide security for the transmission of information on the vast network of sensors, a network that is increasing in size and number. This paper describes the problem of security on networked devices and describes the main algorithms and processes that provide security to this technology. It is concluded that since the devices that form the Internet of things have little memory and processing, it is necessary to apply algorithms that use the least amount of bits, with encryption algorithms that are based on elliptic curves. The advancement of technologies and algorithms that provide security should be considered, because every day we are more dependent on the internet of things.
