Comparison of Encryption Algorithms for Wearable Devices in IoT Systems

Abstract

In industrial, medical, transportation and other key applications, the dependence on the Internet of Things applications is increasing rapidly, which has greatly changed the security landscape. In the past, enterprise applications generally had available resources to deal with security algorithms at any time, but nowadays, enterprise-level IoT applications are suffering from increasing threats, and their attack targets are the expanding network of resource-constrained IoT devices. When enterprises are eager to meet the rapidly emerging opportunities of the Internet of Things, the deployed IoT devices often fail to support basic security measures in function, so it is difficult to protect the stored data, and it is impossible to guarantee the exchange of data and commands on vulnerable networks. The thesis is about the comparison of encryption algorithms for wearable devices. Because the most popular wearable devices in the market are smartwatches, choosing the smartwatches as sample to analysis. Moreover, based on the current cryptographic protocol standards that are being used in IoT, choosing AES, PRESENT, RSA and ECC algorithms as the comparison in the encryption algorithms. Also, the hybrid algorithm called HAN show impressive potential and security in encryption.
