A High - speed Method of RSA Algorithm in Data Encryption
Xue Zhi Xiang · Journal of Nantong Vocational & Technical Shipping College · 2003
The algorithm RSA based on the numberic theory is one of the best encryption algor ithm p ublic - key cryptosystems. It is much complicated and difficult in encrypting and decrypting, because it has to calculate the big numbers more than 100 digits. The main factor that affects the calculating speed of RSA is the algorithms of the exponentiation calculation and modular calculation on big numbers . The paper discusses how to improve the algorithms of the exponentiation calculation and the modular calculation to increase the calculation speed of RSA.
