FPGA Implementation of High Speed RSA Cryptosystem Using Radix-4 Modified Booth Algorithm and CSA
Radix-4 Modified Booth 알고리즘과 CSA를 이용한 고속 RSA 암호시스템의 FPGA 구현
Abstract
This paper presented a new structure of RSA cryptosystem using modified Montgomery algorithm and CSA(Carry Save Adder) tree. Montgomery algorithm was modified to a radix-4 modified Booth algorithm. By appling radix-4 modified Booth algorithm and CSA tree to modular multiplication, a clock cycle for modular multiplication has been reduced to (n+3)/2 and carry propagation has been removed from the cell structure of modular multiplier. That is, the connection efficiency of full adders is enhanced.
