摘要： A device stores one-time pad data for use in carrying out various tasks. In order to preserve the ability to carry out important tasks that require the use of one-time data, use of the one-time pad data held by the device is controlled such that an amount of this one-time pad data is only usable by a predetermined set of important tasks comprising at least a replenishment task for replenishing the device with one-time pad data.

摘要： Secret random data is distributed to a plurality of devices to provision them with new one-time pad data for use in interacting with apparatus holding the same one-time pad data. This distribution is effected by provisioning a first device with a block of secret random data that is, or will become, available to the apparatus. Part of the secret random data is then distributed from the first device to one or more other devices in a hierarchical distribution pattern headed by the first device. Each device, other than those at the bottom of the distribution hierarchy, retains part of the secret random data it receives and passes on the remainder. Each device uses that part of the secret random data it has retained to provide the device with new one-time pad data. A method is also provided for tracking service usage based on the distributed one-time pad data.
摘要翻译：秘密随机数据被分配给多个设备以向它们提供新的一次性填充数据，以用于与保持相同的一次性填充数据的设备进行交互。这种分配是通过向设备提供具有或将成为可用于该设备的秘密随机数据块来实现的。然后，秘密随机数据的一部分以由第一设备为首的分层分布模式从第一设备分发到一个或多个其他设备。每个设备，除了分布层次底部的设备，保留了其接收的一部分秘密随机数据，并传递给其余部分。每个设备使用其保留的秘密随机数据的该部分为设备提供新的一次性填充数据。还提供了一种基于分布式一次性衬垫数据来跟踪服务使用的方法。

摘要： A device is arranged to carry out security-related tasks using one-time pad data. The device has a memory for holding multiple one-time pads, each pad having a different security rating and being intended for use by the device in executing a task to that security rating. Provisioning of the pads with one-time pad data involves carrying out a process for obtaining new secret random data. This process has a security rating with the value of this rating varying according to the nature and parameters of the process concerned. The security rating of the process used to obtain the new secret random data is matched to that of the pad to be provisioned with one-time data, or the other way around, such that the security rating of the process is as least as good as that of the pad to be provisioned.

摘要： A secure transaction method is provided for publicly-accessible transaction terminals. The method uses quantum key distribution (QKD) between a hand-portable QKD device and a complimentary QKD apparatus incorporated the transaction terminal. After the QKD device has been brought up to the transaction terminal, the QKD device and the complimentary QKD apparatus of the terminal are is used to provide the device and terminal with new secret shared random material.

摘要： A quantum key distribution (QKD) method involves the sending of random data from a QKD transmitter to a QKD receiver over a quantum signal channel, and the QKD transmitter and receiver respectively processing the data transmitted and received over the quantum signal channel in order to seek to derive a common random data set. This processing is effected with the aid of messages exchanged between QKD transmitter and receiver over an insecure classical communication channel. The processing concludes with a check, effected by an exchange of authenticated messages over the classical communication channel, that the QKD transmitter and receiver have derived the same random data set. At least some of the other messages exchanged during processing are exchanged without authentication and integrity checking. A QKD transmitter and QKD receiver are also disclosed.

摘要： First data to be sent by a first party to a second party is encrypted using an encryption key string formed using at least a hash value generated using second data and a secret, shared with a trusted party, that serves as identification of the first party. The second data comprises, for example, one or more conditions that serve as identifiers of the second party, and a hash-value element generated by hashing the first data. The encrypted first data and the encryption key string is made available to the second party which forwards the encryption key string to the trusted party with a request for the corresponding decryption key. The trusted party carries out at least one check on the basis of data contained in the encryption key string and, if this at least one check is satisfactory, provides a decryption key to the second party.
