    • An online certificate verification apparatus for an offline device and a verifying method thereof are provided to reduce OCSP calculation quantity of an offline device with low performance by transferring an OSCP request message generating cost to the online device with high performance. An online certificate verification apparatus for an offline device includes a nonce generating unit(310), a transceiver(320), and an certificate verification result determining unit(330). The nonce generating unit generates the nonce and includes the generated nonce. The nonce generating unit produces the certificate vilification request message about the target online device to be authenticated. A transceiver transmits the generated message to the online device. The transceiver receives the OCSP response message about the target online device from the online device. The certificate verification result determining unit extracts the nonce from the received message. The certificate verification result determining unit determines the reliability of the received message by comparing the generated nonce with the extracted nonce.
    • 提供一种用于离线设备的在线证书验证装置及其验证方法,以通过将OSCP请求消息生成成本以高性能传送到在线设备来降低具有低性能的离线设备的OCSP计算量。 用于离线设备的在线证书验证装置包括随机产生单元(310),收发器(320)和证书验证结果确定单元(330)。 随机数生成单元生成随机数,并包括生成的随机数。 随机产生单元产生关于要认证的目标在线设备的证书诽谤请求消息。 收发器将生成的消息发送到在线设备。 收发器从在线设备收到关于目标在线设备的OCSP响应消息。 证书验证结果确定单元从接收到的消息中提取随机数。 证书验证结果确定单元通过将生成的随机数与提取的随机数进行比较来确定接收到的消息的可靠性。

    • A managing apparatus for security data and a method thereof are provided to secure the reliability of the security data by preventing the loss of the security data and the illegal copy. A managing apparatus for security data includes a host device(100) and a security multimedia card(200). The host device includes an approaching mode setting unit, a transmitting/receiving unit, and an approaching information managing unit. The approaching mode setting unit sets up the approaching mode about the security data which is saved in the multimedia card for the security. The transmitting/receiving unit transmits the approaching require message which includes the set approaching mode. The approaching information managing unit receives the approaching information which is saved in the multimedia card for the security after the disconnection with the multimedia card for the security, and compares the checked approaching information. The approaching mode includes at least one of the generation, the leading, the writing, and the deleting.
    • 提供一种用于安全数据的管理装置及其方法,用于通过防止安全数据和非法拷贝的丢失来确保安全数据的可靠性。 用于安全数据的管理装置包括主机设备(100)和安全多媒体卡(200)。 主机设备包括接近模式设置单元,发送/接收单元和接近信息管理单元。 接近模式设置单元设置关于保存在多媒体卡中的安全数据的接近模式以用于安全。 发送/接收单元发送包括设定接近模式的接近要求消息。 接近信息管理单元在与用于安全性的多媒体卡断开之后接收保存在用于安全性的多媒体卡中的接近信息,并且比较所检查的接近信息。 接近模式包括生成,前导,写入和删除中的至少一个。
