摘要
文章对刊载于《计算机工程与应用》2003年第3期、题名为“基于双密钥的高强度公钥密码体制的研究”的文章进行了分析,指出该文提出的将RSA和Elgamal串起来用的公钥密码体制不能增加安全强度。同时,文章阐述了目前公钥密码体制的安全现状和今后的研究方向。
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.
