    • A timed erasure mechanism can be used with portable computer-readable media to ensure automatic erasure of secure information, minimizing the security risks in using such media to store and transport passwords, codes, keys and similar private setup information. The portable computer-readable media can comprise volatile memory and a timed erasure mechanism in the form of a power supply and discharging circuitry that discharges the power supply after a predetermined amount of time. Alternatively, the portable computer-readable media can comprise nonvolatile memory and a timed erasure mechanism in the form of a digital time and erasure algorithms that are initiated after a predetermined amount of time. Furthermore, such portable computer-readable media can comprise a container that bears unique physical properties that can alert users to the volatile nature of the media.
    • 定时擦除机制可以与便携式计算机可读介质一起使用,以确保安全信息的自动擦除,从而最小化使用这种媒体来存储和传输密码,代码,密钥和类似私有设置信息的安全风险。 便携式计算机可读介质可以包括易失性存储器和在预定时间量之后对电源进行放电的电源和放电电路形式的定时擦除机构。 或者,便携式计算机可读介质可以包括在预定时间量之后启动的数字时间和擦除算法形式的非易失性存储器和定时擦除机制。 此外,这种便携式计算机可读介质可以包括具有独特物理特性的容器,其可以向用户提醒媒体的挥发性质。

    • A process for establishing secure mutual trust includes generating a one-time-password. The one-time-password is transferred between the devices in a communication occurring off of the network. Each device generates a set of authenticators by hashing a plurality of sub-strings of the password and the device's authentication certificate with a respective set of nonces. The devices exchange the respective sets of authenticators. Each device then alternates revealing its respective set of nonces and its authentication certificate in a multi-stage process. The devices re-calculate the authenticators based upon the respective set of nonces and authentication certificate revealed by the other device along with the one-time-password sub-strings that it posses. If each device determines that the authenticators re-calculated by the given device matches the authenticators previously received from the other device, secure mutual trust is established.
    • 建立安全互信的过程包括生成一次性密码。 一次性密码在网络中发生的通信中在设备之间传输。 每个设备通过用相应的一组随机数散列密码的多个子串和设备的认证证书来生成一组认证者。 设备交换相应的认证器组。 然后,每个设备在多阶段过程中交替显示其相应的一组随机数及其认证证书。 设备根据由其他设备显示的相应的一组密钥和认证证书及其拥有的一次性密码子字符串重新计算认证者。 如果每个设备确定由给定设备重新计算的认证者与先前从另一设备接收到的认证者匹配,则建立安全的相互信任。
