Therefore,any data send from IoT devices are prevented leakage, and realized a frexible access control.The Functional encryption achieve above contributions. In this paper, we propose that an implementation method of improving processing speed on ARM Cortex-M. We implimemt a precomputation method proposed by Lim and Lee using ROM region. IoT devices have a few RAM region but a lot of ROM region (order Mbyte).
