    摘要： A method and computing device are provided for processing user events received via a user interface, such as a touchscreen, in multiple threads. When a user event is received for a target element in a webpage, the user event is dispatched to both a main browser thread and a secondary thread. The secondary thread processes user events in accordance with established default actions defined within the browser, while the main thread processes the user events in accordance with any event handlers defined for that target element. The main thread processing may be delayed by other interleaved task, and the secondary thread may be given priority over the main thread. When the secondary thread completes processing, an updated webpage is displayed. When the main thread subsequently completes processing, its updated rendering of the webpage is displayed. The secondary thread thus provides an early user interface response to the user event.

    摘要翻译： 提供了一种方法和计算装置，用于处理经由诸如触摸屏的用户界面在多个线程中接收的用户事件。 当为网页中的目标元素接收到用户事件时，将将用户事件分派到主浏览器线程和辅助线程。 次要线程根据在浏览器中定义的已建立的默认动作来处理用户事件，而主线程根据为该目标元素定义的任何事件处理程序处理用户事件。 主线程处理可能被其他交错任务延迟，次级线程可能优先于主线程。 辅助线程完成处理后，将显示更新的网页。 当主线程随后完成处理时，显示其更新的网页呈现。 次级线程因此提供对用户事件的早期用户界面响应。

    摘要： A first device with a changing identity establishes a secure connection with a second device in a network by acting as its own certificate authority. The first device issues itself a self-signed root certificate that binds an identity of the first device to a long-term public key of the first device. The root certificate is digitally signed using a long-term private key, where the long-term public key and the long-term private key form a public/private key pair. The first device provides its root certificate to the second device in any trusted manner The first device can then create a certificate for one or more short-term identities acquired by the first device and sign the newly-created certificate using the long-term private key. The first device can authenticate itself to the second device by sending the newly-created certificate to the second device.

    摘要： A system, methods and devices for the secure notification of an identity in a communications network. The methods include sending or receiving a communication including a hash of a certificate of a device to notify or detect the presence of the device in a network. Each certificate is associated with an identity which is excluded from the communication of the hash of the certificate. The received hash is compared to hashes of certificates stored in an electronic device to determine an identity. The identity may represent an electronic device or a user of the electronic device.

    摘要： A system and method for providing an indication of randomness quality of random number data generated by a random data service. The random data service may provide random number data to one or more applications adapted to generate key pairs used in code signing applications, for example. In one aspect, the method comprises the steps of: retrieving random number data from the random data service; applying one or more randomness tests to the retrieved random number data to compute at least one indicator of the randomness quality of the random number data; associating the at least one indicator with at least one state represented by a color; and displaying the color associated with the at least one indicator to a user. The color may be displayed in a traffic light icon, for example.

    摘要： An electronic device may maintain separate OS domains associated with security permissions. The OS domain may implement separate corresponding clipboard services. A clipboard agent or clipboard mediator service may receive a clipboard data request from a first application. The clipboard agent may determine which OS domain has most recently processed a store command associated with storing data in a corresponding clipboard service of the OS domain. The clipboard agent associated with the OS domain that most recently stored content may determine whether to send the data from the corresponding clipboard service based at least in part on permissions associated with the OS domain. Security of the clipboard access may be enforced on a per domain basis. Access to clipboard content may be mediated at the time of the request without a need to share data prior to the request.
