    • A computer-implemented authenticated encryption method for converting a plaintext message into a ciphertext message. The method includes dividing the plaintext message into at least two working blocks, each working block having a mathematical relationship to the plaintext message. For each working block, a working block ciphertext is computed as a function of such working block, a deterministic working block initialization vector, and a deterministic working block encryption key. For each working block, a message authentication tag is computed as a function of a deterministic working block message authentication key and at least one of (a) the working block ciphertext computed for such working block and an indication corresponding to the mathematical relationship of such working block to the plaintext message and (b) such working block. The method further includes computing a global message authentication tag as a function of the message authentication tag computed for each working block and a global message authentication key. The ciphertext message comprises the working block ciphertext computed for each working block and the global message authentication tag.
    • 一种用于将明文消息转换为密文消息的计算机实现的认证加密方法。 该方法包括将明文消息划分为至少两个工作块,每个工作块与明文消息具有数学关系。 对于每个工作块,根据这种工作块,确定性工作块初始化向量和确定性工作块加密密钥来计算工作块密文。 对于每个工作块,消息认证标签被计算为确定性工作块消息认证密钥的函数,并且(a)为这种工作块计算的工作块密文和对应于这种工作块的数学关系的指示中的至少一个 封闭明文信息,(b)这样的工作块。 该方法还包括根据为每个工作块计算的消息认证标签和全局消息认证密钥来计算全局消息认证标签。 密文消息包括为每个工作块和全局消息认证标签计算的工作块密文。

    • An assembly (20) for controlling movement of an automatically moveable door panel (22) includes sensors (30, 50) such as microswitches positioned on at least one of a door panel (22) or a door frame member (26). The sensors provide an indication of different levels of relative movement between the door panel and the door frame member at an interface (28) between them. Such relative movement includes an increase in a gap between them that corresponds to a situation when an object is at the interface (28) and may be caught. The sensors (30, 50) respectively provide an indication of when an object may become caught and when one has.. Automated movement of a door is controlled responsive to an indication of the presence of an object in a location where the object may become caught during automatic movement of the door.
    • 用于控制可自动移动的门板(22)的移动的组件(20)包括诸如位于门板(22)或门框构件(26)中的至少一个上的微动开关的传感器(30,50)。 这些传感器提供了门板和门框构件之间在它们之间的界面(28)处的不同水平的相对运动的指示。 这种相对运动包括它们之间的间隙的增加,其对应于当物体在界面(28)处并可能被捕获的情况。 传感器(30,50)分别提供对物体何时被捕获的指示以及何时有物体的指示。响应于在物体可能被捕获的位置处存在物体的指示来控制门的自动移动 在门的自动移动期间。
