| Abstract(in English) | Encrypting and decrypting RSA require many exponentiation calculations, and modulo calculation with bit-with wider than lO24bit. To accelerate such calculations, many researchers have developed hardware accelerators. These hardware accelerators deal with large bit width by using many operation units with smaller bit width. However, the calculation method requires many additions to sum up carry outputs caused by summation, which increase execution time of RSA cryptography. This paper shows a novel reconfigurable processor which has an acceleration mechanism for such carry calculations. We evaluated the performance and usage of hardware resources. Compared with the reconfigurable processor without the proposed carry acceleration, as the result the number of computing units used was decreased to 1/318, and the execution time was decreased to 1/22. |
