   In the past few years, the root of trust for computer systems has quickly shifted from software to firmware, then to hardware. Within multiple candidate techniques, physically unclonable function (PUF) is a very attractive and promising solution. PUF has the special features of hardware-oriented, difficult to counterfeit, and highly efficient. In this talk, we will introduce its applications in the scenarios of Smart Health. Specifically, we will introduce encryption free authentication mechanisms among sensor pairs and within sensor groups in wireless body area networks (BAN). In body area networks, power consumption and computation overhead are top priority for any security measures. Using PUF, we allow sensors to achieve encryption free authentication and data integrity protection. The approaches support dynamic changes to the relationship among sensors and group membership.
