Research and analysis on model of testing and quantitating strength about RSA keys

The RSA algorithm is applied very broadly in the information security domain,its security has undergone examining over dozens of years practice.However the algorithm security and the key safe are two different concepts,the latter often is neglected by the people,in the big number of realization,when the RSA algorithm is used to generate the key,the people lack the understanding to the key itself security,thus the strong algorithm is aslo used to initiate the security problem.The RSA key the security measure question is revolved,beginning from the known plaintext RSA attack and the mathematical model on the measure of the RSA key security and the key safety coefficient concept system are proposed,strength coefficient-key quantity distribution is analyzed,a method to quantitate the key intensity is designed,the algorithm to generate RSA key is improved,and then the simulation analysis to it in the 1800 clustering computer platforms is carried on,whole of work has a lot of positively value of reference regarding strengthening the RSA algorithm rea-lization the security.
