| 摘 要： | CA私钥的安全性决定了数字签名本身的有效性.为了保证CA所颁发的数字证书的有效性,提出一种CA签名私钥的高安全性保护和使用方案.算法使用RSA算法产生CA私钥,基于改进的（t,n）秘密共享机制将CA私钥进行分步保存,并使用其身份作为私钥份额的标识;在进行数字签名时,设计了一种无需重构CA私钥的分步签名方案.仿真实验结果表明,所提方案有效增强了CA私钥的安全性.

| Abstract: | The validity of digital signatures depends on certificate authority（CA） private key.To ensure the validity of digital certificate,a protection scheme of private key with high security is proposed.The CA private key is generated by using the RSA algorithm,and then it is shared based on the new（t,n） secret sharing mechanism.It uses its identification as a share of the private key.Furthermore,it is no need to reconstruct the CA private key to sign.Experimental results of the simulation show that the proposed scheme enhance the security of CA private key. |
