浅析免撤销公钥框架(PKI)

Analysis on the Revocation-Free PKI

数字签名通常作为不可反驳的密码学证据用于解决电子交易中的纷争,但是其可信的时间戳和证书撤销服务在实际使用中代价很高。免撤销公钥框架作为一种新的PKI使得终端用户可以控制他自己的公钥证书的有效性,使验证证书不需要折回到CA去获取证书撤销信息,从而降低其使用代价。

Digital signatures usually serve as irrefutable cryptographic evidence to support dispute resolution in electromc transactions. But it is very expensive. As a new type of PKI, non-repudiation PKI make makes the terminal users able to control the validation of his CA, which will reduce the expense.
