    摘要： A system, apparatus, method, and computer-readable medium are provided for secure P2P caching. In one method, a requesting peer obtains a hash of requested data from a server. The requesting peer then transmits a request for the data to other peers. The request proves that the requesting peer has the hash. If a caching peer has the data, it generates a reply to the request that proves that it has the requested data. If the requesting peer receives a reply from a caching peer, the requesting peer establishes a connection to the caching peer and retrieves the data from the caching peer. If the requesting peer does not receive a reply to the request from any other peer, the requesting peer establishes a connection to the server and retrieves the data from the server. The requesting peer stores the data for use in responding to requests from other peers.

    摘要： A computer in a network runs a verification procedure in which it sends data packets to another computer in the network. Some or all of the data packets contain, either individually or collectively, a secret piece of information, such as a secret code. The computer then makes a determination regarding the network links between it and the other computer. If, for example, the other computer is able to respond by providing the secret piece of information back, then the computer sending the data packets concludes that the devices along the network links en route to the other computer are properly forwarding data packets.

    摘要： A strategy is described for assessing and mitigating vulnerabilities within a data processing environment. The strategy collects access data that reflects actual log-in behavior exhibited by users in the environment. The strategy also collects rights data that reflects the rights possessed by one or more administrators within the environment. Based on the access data and rights data, the strategy identifies how a user or other entity that gains access to one part of the environment can potentially compromise additional parts of the environment. The strategy can recommend and implement steps aimed at reducing any identified vulnerabilities.

    摘要： In a cryptographic system, a certificate is used to provide information regarding a client device. The certificate is blindly signed by a certifying authority to preserve the anonymity of the client device. However, information is encoded into the signature so that a content server can readily verify security attributes of the client device and make decisions regarding the delivery of electronic content to the client device based on those security attributes.

    摘要： Manifest-based trusted agent management in a trusted operating system environment includes receiving a request to execute a process is received and setting up a virtual memory space for the process. Additionally, a manifest corresponding to the process is accessed, and which of a plurality of binaries can be executed in the virtual memory space is limited based on indicators, of the binaries, that are included in the manifest.

    摘要： An implementation of a technology, described herein, for facilitating the automated generation of input-validation software filters. The implementation of the invention provides an easy graphical user interface (GUI). With this GUI, a user (such as a system administrator) is able to quickly enter a set of parameters defining what valid inputs constitute—in particular, when such inputs come from a computing component. Consequently, the user does not have to manually generate filtering instructions on how to filter input from a computing component. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

    摘要： A system and method for secure purchase and delivery of video content programs over various distribution media, including distribution networks and digital video disks, includes an integrated circuit card (e.g., a smart card, PCMCIA card) which is configured to store decryption capabilities for related video programs. The decryption capabilities are initially kept in a secure store at a video merchant. When a purchaser orders a particular video program, the decryption capabilities for that program are downloaded to the IC card, either at the merchant premises or over a distribution network. The video content program is distributed in encrypted format via the distribution media to the purchaser. The IC card uses the decryption capabilities to at least partly decrypt the video content program without exposing the decryption capabilities.
