    摘要: A “Performance Evaluator” provides various techniques for tracking system events to diagnose root causes of application performance anomalies. In general, traces of system events involved in inter-thread interactions are collected at application runtime. These traces are then used to construct inter-thread dependency patterns termed “control patterns.” Control patterns are then evaluated to determine root causes of performance anomalies. Where an application terminates abnormally or full traces cannot be collected for some reason, partial control patterns are constructed for that application. In various embodiments, “fingerprints” are then generated from full or partial control patterns and are matched to fingerprints corresponding to operations in other control patterns extracted from reference traces collected on the same or similar systems. Matched fingerprints or control patterns are then used to deduce the root cause of application performance anomalies associated with full or partial traces.

    摘要: A security-enhanced login technique that provides a convenient and easy-to-use two factor technique to enhance the security of passwords without requiring any changes on the server side of a client-server network. The technique employs a convenient and easy-to-use two-factor technique to generate strong passwords for Web and other applications. In this technique, a convenient or personal device such as a mouse is used as the other factor besides a user password. A secret stored in the mouse or other personal device is hashed together with the password entered by a user and the server ID, to generate a strong, server-specific password which is used to authenticate the user to the server. This password enhancement operation is carried out inside the personal device.

    摘要: Methods and systems for parallel Web page processing are usable to parallelize Web page document parsing, Web page layout calculations, Web page style formatting, and Web page script engine processing. Such parallelized parsers may be used to enhance Web page processing and exploit multi-core and multi-processor computing device resources. The parallelized script engine may be used to enhance Web page processing when independent scripting events exist in the Web page document. Additionally, the parallelized layout calculations and style formatting may be used to further enhance Web page processing by allowing multi-core and multi-processor computing devices to take advantage of their parallel processing abilities.

    摘要: A cross-module detection system and method for detecting and monitoring control flow transfers between software modules in a computer system. The system and method detect and monitor control flows entering and exiting the software modules. For a particular module, a checking model is extracted from the binary file of that module. In addition, a relaxed shadow stack is generated. If the module is an original module, meaning that the control flow originated from that module, then the checking model is used to check the validity of the control flow transfer. Otherwise, the relaxed shadow stack is used. An interception module is used to intercept and terminate invalid control flow transfers. If an invalid control flow transfer is detected, then the transfer is terminated. Otherwise, the control flow transfer is allowed to continue.

    摘要: A component-oriented web mashup system and method for communicating between component-oriented Web gadgets to facilitate secure Web mashups. Embodiments of the system and method redefine the traditional definition of gadget to mean a Web component having a verifiable controlled communication channel (a CompoWeb gadget). A CompoWeb gadget is created and defined using new HTML tags and global script objects and functions that extend the functions of the browser. CompoWeb gadget content is treated as a component that is isolated from other gadgets and frames by a browser, and only those allowed access can view data and code therein. Called functions of a CompoWeb gadget are run in the callee's environment instead of the caller's environment. This adds security, because all the requesting CompoWeb gadget receives is the run result. Embodiments of the system and method also include delayed binding of CompoWeb gadgets, such that binding is performed at run time.

    摘要: A cooperative rendering cache browser (CRC-Browser) for a mobile device may cooperatively manage cached content with a proxy server to reduce redundant transmissions of processed Web data. Additionally, the CRC-Browser may provide stateful, thin-client Web browsing to maintain synchronized information about rendering objects of a Web page. Further, the CRC-Browser may cache only stable and/or visible document object model (DOM) elements and communicate a list of IDs of the cached elements to the proxy. Such stateful thin-client browsers may be useful for reducing battery drain, poor responsiveness, and high wireless network costs of mobile Web browsing.

Such style caching trees may be used to avoid recalculating style content of Web pages for document object model (DOM) elements that have not changed. Additionally, the cacheable layout calculations may be used to avoid recalculating the layout content of Web pages that are subsequently accessed.
