| 摘要 |
The invention relates to an accelerator board for cryptographic processing using an RSA public-key algorithm which involves the acceleration of the exponential computation in modular arithmetic. The inventive implementation employs a method and an original architecture for the exponential computation, comprising: 1) an adder stage which is based on a system of shifts and additions; 2) a multiplier stage which is derived from the algorithm (Montgomery); and 3) an exponentiator step. |
