    • Embodiments are directed to securely filtering trust services records. In one scenario, a client computer system receives at least one of the following trust services records: a trust services certificate, a principal certificate, a group certificate and a trust services policy. The client computer system performs a time validity check to validate the trust services record's timestamp, performs an integrity check to validate the integrity of the trust services record and performs a signature validity check to ensure that the entity claiming to have created the trust services record is the actual creator of the trust services record. The client computer system then, based on the time validity check, the integrity check and the signature validity check, determines that the trust services record is valid and allows a client computer system user to perform a specified task using the validated trust services record.
    • 实施例针对安全地过滤信任服务记录。 在一种情况下,客户端计算机系统接收以下信任服务记录中的至少一个:信任服务证书,主体证书,组证书和信任服务策略。 客户端计算机系统执行时间有效性检查以验证信任服务记录的时间戳,执行完整性检查以验证信任服务记录的完整性,并执行签名有效性检查,以确保声称已创建信任服务记录的实体为 信托服务记录的实际创建者。 然后,客户计算机系统基于时间有效性检查,完整性检查和签名有效性检查,确定信任服务记录是有效的,并允许客户端计算机系统用户使用经过验证的信任服务记录来执行指定的任务。
