    • Methods and apparatus are provided for generating a garbled circuit for a client in a leakage-resilient manner, for use in secure function evaluation between the client and a server. The garbled circuit is generated by obtaining a token from the server, wherein said token comprises a leakage-protected area; querying the token gate-by-gate, wherein for each gate of said garbled circuit, the token interacts with the leakage-protected area to generate a garbled table for the gate; and receiving the garbled circuit from the token. The client can interact with the server to obtain garbled inputs; and then evaluate the garbled circuit on the garbled inputs to obtain a garbled output. A final output can be obtained by matching the garbled output with an output table in the garbled circuit.

    • In one embodiment, a method includes receiving user input to scroll within a GUI on a touch screen. The user input includes a touch gesture having a path that includes a starting point and one or more other points on the touch screen. The computing device determines regions of the touch screen defined with respect to the starting point. A first one of the regions corresponds to a first scrolling axis, and a second one of the regions corresponds to a second scrolling axis perpendicular to the first scrolling axis. If the path corresponds to the first region, then the computing device scrolls within the GUI according to the user input linearly and parallel to the first scrolling axis. If the path corresponds to the second region, then the computing device scrolls within the GUI according to the user input linearly and parallel to the second scrolling axis.
    • 在一个实施例中,一种方法包括接收在触摸屏上的GUI内滚动的用户输入。 用户输入包括具有路径的触摸手势,该路径包括触摸屏上的起点和一个或多个其他点。 计算设备确定相对于起始点定义的触摸屏的区域。 所述区域中的第一个对应于第一滚动轴,并且所述区域中的第二个对应于垂直于所述第一滚动轴线的第二滚动轴。 如果路径对应于第一区域,则计算设备根据用户输入线性地并平行于第一滚动轴在GUI内滚动。 如果路径对应于第二区域,则计算设备根据用户输入线性地并平行于第二滚动轴在GUI内滚动。

    • An embodiment of the present invention provides a computer implemented method for the transfer of private information of one user to another user—a primitive known as Oblivious Transfer. An output from a strong pseudorandom function generation (SPRFG) is calculated by a first user's computing module based on first and second parameters: the first parameter specifying one of two secret keys; the second parameter being a value selected within the domain of the SPRFG by the first user. The first user is prevented from reading or learning the stored two secret keys. The output is transmitted to a computer of a second user which generates first and second encrypted values that are each based on an inverse SPRFG calculation using the first and second secret keys, respectively, and corresponding private values of the second user. The encrypted values are sent to a first computer of the first user that calculates one of the private values using a mathematical computation based on the second parameter and the one of the first and second encrypted values that corresponds to the one of the first and second key used.
    • 本发明的一个实施例提供了一种计算机实现的方法,用于将一个用户的私人信息传送给另一个用户 - 被称为永久传递的原语。 来自强伪随机函数生成(SPRFG)的输出由第一用户计算模块基于第一和第二参数计算:第一参数指定两个秘密密钥之一; 第二参数是由第一用户在SPRFG的域内选择的值。 阻止第一用户阅读或学习所存储的两个秘密密钥。 输出被发送到第二用户的计算机,其产生分别基于使用第一和第二秘密密钥的反向SPRFG计算以及第二用户的对应私有值的第一和第二加密值。 将加密的值发送到第一用户的第一计算机,该第一计算机使用基于第二参数的数学计算和与第一和第二密钥中的一个对应的第一和第二加密值中的一个来计算私有值之一 用过的。

    • An executing first computing module verifies the run-time provenance of an unverified second computing module. A signed certificate identifying an author of the second computing module is received at the first computing module. An association between the signed certificate and the second computing module is verified. A first provenance certificate and associated private key signed by the first computing module and identifying a runtime provenance of the second computing module is then generated, and the first provenance certificate is published to the second computing module. A chain of signed certificates, including provenance certificates and a static identification certificates, can be published. Each provenance certificate in the chain verifies the integrity of a layer of execution, and the plurality of static identification certificates identifies a respective author of the computing module associated with each layer of software. The provenance of the second computing module can be recursively traced through the published chain of certificates.
