Comparison of AES and PRESENT Block Cipher for 6LoWPAN Based Internet-of-Things

Security is one of the most critical element in Internet of Things (IoT) which is often neglected in development. IoT devices demand lightweight but end-to-end authentication mechanism to enable secure access of data and to protect itself from unauthorized access. This paper analyses the security solutions for 6LoWPAN-based IoT networks. We compare the traditional AES with PRESENT block cipher for IoT. Due to its huge consumption of resources, the traditional AES based security mechanisms are not suitable. In order to provide lightweight authentication, PRESENT block cipher is found to be more efficient than conventional AES.
