ABSTRACT
Data privacy and security is a major concern for M-commerce and the Internet of Things. Security measures such as encryption may be implemented to protect confidentiality, integrity and availability. Limitations in processing power, battery life, communication bandwidth and memory constrain the applicability of existing cryptography standards for mobile devices. This paper describes an experiment to investigate the computational requirements for some of the most popular cryptographic algorithms with reference to power and resources consumption. Given reliable information on battery consumption, users can make informed decisions on which security schemes to use.
