实现

The author mainly realized the method of generating the large random numbers and judging the prime number using Lehmann means,then three pairs of secure key with different lengths (256 bits,512 bits,1024 bits) was generated to meet the demand of different security grade. In encryption module,modular multiplication arithmetic of large number was realized adopting addition chaining. In decryption module,extended Euclid was used to get inverse,and the Chinese remainder theorem was used to realize decryption,which increased the speed of decryption greatly.

Where the debt transferred, the concerned right of mortgage is transferred simultaneously, unless otherwise provided by law or agreed by parties. According to the word, the mortgagee and the mortgagor may agree that the mortgage of ship is not transferred with transferred prime debt. But they cannot agree that the right of mortgager is apart from the prime debt to transfer or become the right of mortgage for other debt. Where the debtor' performance ability and credit is better, as well as the debtor and the mortgagor are the same or have affiliated relation, it is possible that the right of mortgage is not transferred with transferred prime debt.

船舶抵押权人可以和抵押人约定除了"债务人不履行到期债务"以外的实现抵押权的情形，如约定当债务人有其他的违约行为或经营不善将影响到债务人的履约能力时、显著的船舶市场行情下降将影响船舶抵押权实现的额度、显著的船况下降将使船舶出现优先权和船舶留置权的可能性增加等情形出现时，船舶抵押权人可以实现债权。

For the partial products generation, the novel method of Booth encoding combined with partial products generating is put up, which can directly map the multiplicand and multiplicator to partition products without generating the BOOTH encoding results. For the optimization of Wallace tree adding, the series formulas of full-adder and 4-2 Compressor realization are introduced to guidance the selection. For the non-bias round, forwarding round disposal in Wallace tree method is brought forward to avoid the final multi-bit adder. Also, the idea of delay-oriented partition of the MAC frame is put up to achieve the perfect match with multi-pipeline DSP architecture.
