摘要： In a communication system having a number of base stations and user devices, a sending user device comprising a processor and a memory is configured to generate a packet or other communication for forwarding to a receiving user device via one or more intermediary user devices of the system. The forwarding path of the communication may involve one or more of the base stations. A payment token is associated with the communication, such that at least one of the intermediary user devices can generate a payment claim based on the payment token. The payment token is independent of the particular identities of the one or more intermediary user devices of the system.

摘要： A method, system and device for allowing the secure collection of sensitive information is provided. The device includes a display, and a user interface capable of receiving at least one user-generated interrupt in response to a stimulus generated in response to content received by the device, wherein the action taken upon receiving the user-generated interrupt depends on a classification of the content, the classification identifying the content as trusted or not trusted. The method includes detecting a request for sensitive information in content, determining if an interrupt is generated, determining if the content is trusted, allowing the collection of the sensitive information if the interrupt is generated and the content is trusted, and performing an alternative action if the interrupt is generated and the content is not trusted. The method may include instructions stored on a computer readable medium.

摘要： Techniques are disclosed for efficient computation of consecutive values of one-way chains and other one-way graphs in cryptographic applications. The one-way chain or graph may be a chain of length s having positions i=1, 2, . . . s each having a corresponding value vi associated therewith, wherein the value vi is given by vi=h (vi+1), for a given hash function or other one-way function h. An initial distribution of helper values may be stored for the one-way chain of length s, e.g., at positions given by i=2j for 0≦j≦log2 s. A given one of the output values vi at a current position in the one-way chain may be computed utilizing a first helper value previously stored for another position in the one-way chain between the current position and an endpoint of the chain. After computation of the given output value, the positions of the helper values are adjusted so as to facilitate computation of subsequent output values. Advantageously, a storage-computation product associated with generation of the output values of the one-way chain has a complexity O((log s)2).
