The quantitative performance indicators of Physical Unclonable Functions (PUFs)\Randomness, Steadiness, Correctness, Diffuseness and Uniqueness\are strictly defined and applied to the evaluation of 45 arbiter PUFs on Virtex-5 FPGAs. The indicators effectively reflect the characteristics of PUFs ranging from 0 to 1 with 1 being the highest(More)
A high-speed and secure dynamic partial reconfiguration (DPR) system is realized with AES-GCM that guarantees both confidentiality and authenticity of FPGA bitstreams. In DPR systems, bitstream authentication is essential for avoiding fatal damage caused by unintended bitstreams. An encryption-only system can prevent bitstream cloning and reverse(More)
A secure and dependable dynamic partial reconfiguration (DPR) system based on the AES-GCM cipher is developed, where the reconfigurable IP cores are protected by encrypting and authenticating their bitstreams with AES-GCM. In DPR systems, bitstream authentication is essential for avoiding fatal damage caused by inadvertent bitstreams. Although(More)
We developed a content delivery system using a partially reconfigurable FPGA to securely distribute digital content on the Internet. With partial reconfigurability of a Xilinx Virtex-II Pro FPGA, the system provides an innovative single-chip solution for protecting digital content. In the system, a partial circuit must be down-loaded from a server to the(More)
A secure content distribution system is prototyped based on run-time partial reconfigurability of an FPGA. The system provides a robust content protection scheme for online content download services. The key idea is to divide the security module in a user terminal into Content-Specific Circuit (CSC) and Terminal Build-in Circuit (TBC) and to dynamically(More)
Fast power current analysis method using capacitor charging model was introduced to evaluate security of cryptographic hardware against side channel attacks before the circuit is fabricated as an LSI chip. The method was applied to CPA (Correlation Power Analysis) on various AES (Advanced Encryption Standard) circuits, which require more than 10,000 power(More)
—Future applications of wireless power transfer will include powering various devices in a room, charging electric vehicles in a parking area, charging moving robots and so on. Therefore practical wireless power transfer must be able to support complicated configurations for example combination of multi-receiver and repeaters. Many past works have discussed(More)
