    • A method and device are useful for enabling a trust relationship using an expired public key infrastructure (PKI) certificate. The method includes determining at a relying party a maximum permissible grace period during which the PKI certificate can be conditionally granted a valid status (step 905). Next, at the relying party an uncertainty interval is determined, during which the relying party is unable to detect a revocation of the PKI certificate (step 910). A certificate grace period is then determined at the relying party from a function of the maximum permissible grace period, the uncertainty interval and at least one attribute defined in the PKI certificate (step 915). Using the PKI certificate, a trust relationship is then enabled between the relying party and a certificate holder of the PKI certificate, after determining the grace period and before an expiration of the grace period (step 920).
    • 一种方法和设备对于使用过期的公共密钥基础设施(PKI)证书启用信任关系很有用。 该方法包括在依赖方确定PKI证书有条件地被授予有效状态的最大允许宽限期(步骤905)。 接下来,在依赖方确定不确定性间隔,在该期间,依赖方不能检测到PKI证书的撤销(步骤910)。 然后根据最大允许宽限期,不确定性间隔和PKI证书中定义的至少一个属性的功能,在依赖方确定证书宽限期(步骤915)。 使用PKI证书,在确定宽限期之后和宽限期到期之前,在依赖方与PKI证书的证书持有者之间启用信任关系(步骤920)。
