摘要： Data to be output to a removable storage medium is encrypted for sending to an output device by an encryption process based on encryption parameters comprising public data of a trusted party and an encryption key string comprising a policy for allowing the output of the data. The trusted party provides a decryption key to the output device but only after being satisfied that the policy has been met. The decryption key is generated in dependence on the encryption key string and private data of the trusted party. The output device uses the decryption key in decrypting the data to be output. Embodiments are provided that involve multiple policies and trusted parties.

摘要： An apparatus (22,44) is described for use in generating configuration information for a computer system (12) employing hierarchical entities.A policy template (24) is employed which contains a definition of an abstract high-level policy, for the configuration of the system, and permitted refinements to that policy, the definition referring to a plurality of the entities. An information and system model (16) contains information about the computer system and its environment including the entities referred to in the high-level policy definition, the hierarchy thereof and non-hierarchical relations between the entities. A policy authoring engine (26) refines the high-level policy definition with reference to the permitted refinements thereto and the stored information about the entities to which the high-level policy definition relates in order to produce a refined policy definition. In doing this, the engine presents refinement options to a user (10) via a user interface (28) and refines the high-level policy definition in dependence upon options selected by the user via the user interface. Some of the entities stored in the model (16) may be abstract entities, but with pointers to data in the computer system representing an instance of that abstract entity. The refined policy may be in terms of a policy context, referring to unbound entities, and a policy statement. A policy deployer (20) stores rules for interpreting the policy statement as instructions executable by the computer system and is operable, with reference to the information and system model (16), to bind the unbound entities in the policy context to instances of those entities, and, with reference to the stored rules, to interpret the policy statement into a series of instructions to the computer system referring to the bound instances or derivatives of them.The apparatus facilitates the refinement of abstract policies and implementation of the refined policies.

摘要： A method of printing a token by printer (5), in which the printer (5) includes a digital identification device (1) configured to generate a series of distinct print job counter numbers and to provide a public key of a cryptographic public key/private key pair. The method includes the steps of sending a printer generated print job counter number and an encryption key to a token issuer (4) the token issuer (4) sending to the printer (5) a message encrypted by the encryption key, the message including the print job counter number and information representative of the token (9) to be printed and the printer (5) decrypting the encrypted message and printing the token using the information representative of the token (9) if the print job counter number is valid.

摘要： A trusted authority delegates authority to a device. This delegation of authority is effected by providing a yet-to-be completed chain of public/private cryptographic key pairs linked in a subversion-resistant manner. The chain terminates with a penultimate key pair formed by public/private data, and a link towards an end key pair to be formed by an encryption/decryption key pair of an Identifier-Based Encryption, IBE, scheme. The private data is securely stored in the device for access only by an authorized key-generation process that forms the link to the end key pair and is arranged to provide the IBE decryption key generated using the private data and encryption key. This key generation/provision is normally only effected if at least one condition, for example specified in the encryption key, is satisfied. Such a condition may be one tested against data provided by the trusted authority and stored in the device.
摘要翻译：受信任的权威机构将权限委托给设备。这种权力的授权是通过提供一个尚未完成的公开/私人加密密钥对链，以颠覆性的方式连接起来。链终止于由公共/私有数据形成的倒数第二个密钥对，以及通过基于标识符的加密（IBE）方案的加密/解密密钥对形成的终端密钥对的链接。专用数据被安全地存储在设备中，仅由形成到终端密钥对的链接的授权密钥生成过程访问，并且被设置为提供使用专用数据和加密密钥生成的IBE解密密钥。这种密钥生成/提供通常仅在满足例如在加密密钥中指定的至少一个条件时才有效。这样的条件可以针对由可信管理机构提供并存储在设备中的数据进行测试。

摘要： To control access to target data whilst relieving the data provider of policing obligations, the data provider provides the target data in encrypted form to a requesting party as part of a data set with which first and second trusted authorities are associated in a non-subvertible manner. Recovery of the target data in clear by the party requires the first trusted authority to verify that a specific individual is a professional accredited with it, the second trusted authority to verify that a particular organisation is accredited with it, the particular organisation to verify that the specific individual is engaged by it, and at least one of the particular organisation and the first trusted authority to verify that the party is the specific individual. Various ways of encrypting the target data are provided, the preferred ways being based on Identifier-Based Encryption schemas.
