| Abstract(in English) | We designed a high-speed modular exponentiation unit for RSA cryptosystem, which is one of the most representative public key cryptosystems. For acceleration, we tried to reduce clock cycles for the calculation, and now we developed an algorithm appropriately combining two efficient algorithms, that are called Left-to-Right k-ary method and Montgomery multiplication. We also tried to reduce the cycle time by dividing the critical-path in the unit. We have the result that the unit can calculate a. 1024 bit modular exponentiation for 3.2 ms. This unit has high-speed capability and implementable size on an LSI chip. |
