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： A computer system comprises a first computer entity arranged to encrypt data using an encryption key comprising a time value, and a second computer entity arranged to generate, at intervals, a decryption key using a current time value. The encryption and decryption processes are such that the decryption key generated using a current time value corresponding to that used for the encryption key, is apt to decrypt the encrypted s data.

摘要： When sending personal data to a recipient, the data owner encrypts the data using both a public data item provided by a trusted party and an encryption key string formed using at least policy data indicative of conditions to be satisfied before access is given to the personal data. The encryption key string is typically also provided to the recipient along with the encrypted personal data. To decrypt the personal data, the recipient sends the encryption key string to the trusted party with a request for the decryption key. The trusted party determines the required decryption key using the encryption key string and private data used in deriving its public data, and provides it to the requesting recipient. However, the decryption key is either not determined or not made available until the trusted party is satisfied that the associated policy conditions have been met by the recipient.

摘要： A software system for installation on computing apparatus (and a method of installing such a software system on computing apparatus), wherein the software system is provided in the form of a software package including a plurality of software components, one or more of the software components being provided as a plurality of different implementations, the apparatus including an installation engine for installing the software system only a selected one implementation of the or each of the software components having multiple implementations, and a random selector module for selecting one of the plurality of implementations of a software component for installation. Thus, software package would still be distributed to its consumers as a single version but each installation of the package on a user's computing apparatus is potentially different, which reduce the risk of faults in and attacks against software components having one or more “bugs” therein because not all consumers will have the same implementation of any one software component.

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.

摘要： A system is disclosed in which a plurality of devices are arranged to use one-time pad data to interact with apparatus holding the same one-time pad data. Each of the devices and the apparatus has its own one-time pad and the pads are all provisioned with the same new one-time pad data. Upon any one of the devices wishing to effect an interaction with the apparatus using one-time pad data, an alignment operation is carried out between a set of entities comprising at least the apparatus and the device wishing to carry out the interaction. The alignment operation serves to reduce the level of the one-time pad of at least the device wishing to carry out the interaction, to the level of the lowest one-time pad of the set of entities involved in the alignment operation.
