| Abstract: | This paper analyses the thesis published in“Computer Engineering and Applications”,No.3,2003,which is entitled“Public_key Cryptosystem Design Based on Two Private Keys”,and points out this cryptosystem with RSA and Elgamal in series can't strengthen security intensity.Then,is paper expatiates on actuality of public-key cryptosystem and the research direction for the future. |
