This brief presents a novel and efficient design for a Rivest–Shamir–Adleman (RSA) cryptosystem with a very large key size. A new modular multiplier architecture is proposed by combining the fast Fourier transform-based Strassen multiplication algorithm and Montgomery reduction, which is different from the interleaved version of Montgomery multiplications used in traditional RSA designs. A new modular...
A high performance table-based architecture implementation for CRC (cyclic redundancy check) algorithms is proposed. The architecture is designed based on a highly parallel CRC algorithm. The algorithm first divides a given message with any length into bytes. Then it performs CRC computation using lookup tables among the divided bytes in parallel. At last, the results are XORed to obtain the CRC value...
Modular multiplication is the most crucial component in RSA cryptosystem. In this paper, we present a new modular multiplication architecture using the Strassen multiplication algorithm and Montgomery reduction. The architecture is different from the interleaved version of Montgomery multiplication traditionally used in RSA design. By selecting different bases of 16 or 24 bits, it could perform 8,192-bit...
Mobile WiMAX's scheduling service is a key factor in Radio Resource Management (RRM) in realizing Quality of Service (QoS). The choice in scheduling algorithm for Mobile WiMAX base stations, albeit outside of the scope of the standard, critically impacts the performance and robustness of Mobile WiMAX networks. This paper provides an in-depth study of four major scheduling algorithms: Round Robin (RR),...
