Kristtopher K. Coelho holds B.Sc. and M.Sc. degrees in Computer Science from Universidade Federal de Viçosa, Brazil. He is currently a Computer Science Ph.D. candidate at the same university working on security for body area networks. Research background comprises evaluating the practical impact of the lightweight block and stream cipher algorithms on power consumption and hardware resources for wearable devices. It also includes studying the skin as a secure channel to transmit sensitive data such as cryptography keys. In this application scenario, we can provide more security and solve the management problem of secret key cryptographic algorithms. His research background also involves the development of low-cost electronic systems to transfer using the ionic environment.
