This paper describes two encryption designs of Chinese wireless local area network block cipher standard - SMS4 algorithm. Then these two designs are implemented on Xilinx Virtex-4 FPGA devices. The first (pipelined) design is optimized in order to reduce time delay and the encryption core has a throughput of 24 Gb/s. The second (folded) design is optimized(More)
Modular reduction is the basic operation of cryptographic systems. The Barrett's algorithm and Montgomery's algorithm are widely used nowadays and they are both based on pre-computation. In the field of elliptic curve cryptosystem (ECC) over GF(2<sup>m</sup>), the reduction polynomials recommended by SEC have few items and the degree of second item is much(More)
The paper presents a new stochastic model for mesh-based reconfigurable computing. Under the conditions of several statistical assumptions, closed formulae of probability and mathematical expectation are derived for each type of connections. Both the theoretical deduction and simulation results are given to verify our approach. The elementary research can(More)
