本文介绍了由Okamoto提出的公开密钥密码体制的一种改进。这种改进看来似乎是抗Shamir对于原密码体制的密码分析的攻击的。此外,文章还提出了一种变型,它因为加密而造成的数据扩充率要小于这种改进的数据扩充率。
This article describes an improvement of the public key cryptosystem proposed by Okamoto. This improvement appears to be an anti-Shamir attack on the cryptanalysis of the original cryptosystem. In addition, the article also proposed a variant, which due to encryption data expansion rate is less than this improved data expansion rate.
