摘要： Public key encryption methods and apparatus are provided for encrypting secret data under a public key in a data processing system (1). The secret data is provided as a message (m) comprising at least one element of a pair of base groups G1, G2 satisfying a bilinear map ê: G1×G2→GT where GT is a target group. The message (m) is encrypted using said public key to produce an encrypted message (c). A consistency component (v) is generated using the encrypted message (c) and said bilinear map whereby the consistency component (v) permits validation of the encrypted message without revealing the encrypted message. The output ciphertext (ct) comprises the encrypted message (c) and the consistency component (v).

摘要： Data security devices are provided which store user data and interact with terminal devices to provide information about the stored user data. Security device has memory for storing user data, an interface for transmission of data communications connectable to a data communications network, and a controller. The controller processes a request from the terminal device for information about said user data by first generating a message. The message is generated to permit verification, using secret data, that the message was generated by the controller. The controller sends the message to the terminal device for communication to a publication entity for publication of the message. The controller then receives from the terminal device a cryptographic construction. The controller checks validity of the cryptographic construction for said message, and subsequent supply of the information requested about the user data to the terminal device is then dependent on said cryptographic construction.

摘要： Techniques are disclosed for issuing inoperative credentials, and making the inoperative credential operative at a subsequent point in time. For example, a method of forming a credential comprises the step of forming, at a first point in time, an inoperative credential. The inoperative credential is adapted to become operative, at a second point in time, to form an operative credential. The second point in time occurs after the first point in time.

摘要： A method for joint generation of a ciphertext by devices of a data processing system includes providing, by a first device, a first message, representing secret data of the first device, generating an initial ciphertext comprising an initial blinded encrypted message, in which the first message is encrypted under a public key of a trusted entity, and an initial consistency component for validating the initial ciphertext using the bilinear map; and sending the initial ciphertext to a second device; wherein the second device provides a second message, representing secret data of the second device, generates an updated ciphertext comprising an updated blinded encrypted message and an updated consistency component for validating the updated ciphertext, and generating a final ciphertext comprising the final encrypted message and a final consistency component for validating the final ciphertext, wherein the final consistency component is generated using the updated consistency component and the bilinear map.

摘要： Methods and apparatus for forming and presenting confidential presentations within a computing environment associated with a virtual application are presented. For example, a method for forming a confidential presentation includes obtaining a correspondence indicator from an asset server, obtaining a first texture from the asset server, and overlaying the first texture onto a first object. The correspondence indicator indicates the first texture corresponds to the first object. The first object is within the computing environment associated with the virtual application. The first texture and the asset server are inaccessible by the computing environment associated with the virtual application. The confidential presentation comprises the first texture.
