The main contribution of this paper is to present an efficient hardware algorithm for RSA encryption/decryption based on Montgomery multiplication. Modern FPGAs have a number of embedded DSP blocks (DSP48E1) and embedded memory blocks (BRAM). Our hardware algorithm supporting 2048-bit RSA encryption/decryption is designed to be implemented using one DSP48E1, one BRAM and few logic blocks (slices)...
The main contribution of this paper is to present hardware algorithms for redundant radix-2r number system in the FPGA to speed the arithmetic operations for numbers with many bits, which have applications in security systems such as RSA encryption and decryption. Our hardware algorithms accelerate arithmetic operations including addition, multiplication, and Montgomery modulo multiplication.Quite...
The main contribution of this paper is to present hardware algorithms for redundant radix-2r number system in the FPGA to accelerate Montgomery modulo multiplication with many bits, which have applications in security systems such as RSA encryption and decryption. Quite surprisingly, our hardware algorithm for Montgomery modulo multiplication of two dr-bit numbers can be completed in only d+1 clock...
