Implementation of RSA Based on Modified Montgomery Modular Multiplication Algorithm

  title={Implementation of RSA Based on Modified Montgomery Modular Multiplication Algorithm},
  author={Gang Feng and Guangsheng Ma and Zhi Yang},
A modified Montgomery modular multiplication algorithm using four-to-two CSA (carry save adder) was proposed. The modified algorithm avoids the carry delay and the repeated output/input format conversions. We use this modified algorithm to design the RSA processing unit with 512-bit and 1024-bit key size .The resulting RSA units have a high throughput. 


Implementation of RSA Cryptoprocessor Based on Modified Montgomery Modular Multiplication Algorithm
The proposed algorithm only uses one CSA (carry save adder)CSA, so it speeds up the implementation of RSA cryptoprocesser, and also improves the time of the algorithm. Expand

A new RSA cryptosystem hardware design based on Montgomery's algorithm
A new algorithm based on Montgomery's algorithm to calculate modular multiplication that is the core arithmetic operation in an RSA cryptosystem is proposed that eliminates over large residue and has very short critical path delay that yields a very high speed processing. Expand
A hardware version of the RSA using the Montgomery's algorithm with systolic arrays
The novel idea in this paper is to use the systolic array cells with increased performance of up to 20% and use them in a single row organization to speed up the modular multiplication and squaring operation. Expand
