Dynamically configurable security for SRAM FPGA bitstreams

Summary form only given. We propose a solution to improve the security of SRAM FPGAs through bitstream encryption. This proposition is distinct from other works because it uses the latest capabilities of SRAM FPGAs like partial and dynamic reconfiguration. It doesn't need any external battery to store the secret key. It opens a new way of application partitioning according to the security policy.
