Abstract(in English) | Cipher circuits are required both to have high security and to show high performance as to circuit scale and processing speed. One way to improve security is to implement various algorithms or many variations of an algorithm on a circuit. In this case, however, the security is achieved at the cost of the performance, that is, the circuit becomes so large that security and performance do not meet. We therefore employ FPGA partial reconfiguration technique and apply dynamic key methods to provably secure block ciphers in order to achieve both security and performance. We choose the 64 bit block cipher MISTY1, realize the dynamic key modification to it in two ways, the partial reconfiguration one and the usual one using selectors, and compare the results. The study finds that it is effective to use the partial reconfiguration when there are four or more circuits to be selected. |
