  • Publication number: 20190281031
    Abstract: Disclosed are a system, method and devices for simultaneous MACsec key agreement (MKA) negotiation between the devices. The present application controls a basic TLV message exchange between supplicant and authenticator in case of race condition to establish the secure association key (SAK) channel. The present application by controlling a basic TLV message exchange enables to establish a secure channel in race condition and achieves a high reliability of the product as this makes product launch MACsec services quickly and available for the service. Accordingly, when both sides (two supplicants) exchange hello with basic TLV at the same time, triggering the race condition, drops first message from the authenticator at supplicant and update the peer MN and the supplicant will not send reply. The authenticator when send next message (basic+potential peer TLV) with peer MN incremented by 1, the supplicant will respond with incremental message with live peer TLV.

  • Publication number: 20190191307
    Abstract: The method includes: receiving, by a first member device, a second EAPOL-MKA packet sent by a second member device; determining, by the first member device, a first cipher suite, and determining a first secure association key SAK corresponding to the first cipher suite; and sending, by the first member device, the first cipher suite and the first SAK to the second member device in CA. Based on the foregoing technical solution, a device in the CA may determine a cipher suite and a secure association key corresponding to the cipher suite that are used for MACsec secure data transmission. In addition, all devices in the CA support the determined cipher suite. In this way, a problem that the cipher suite needs to be re-determined because one or more devices do not support the cipher suite determined by the first device can be avoided.

  • Publication number: 20180374237
    Abstract: A method of determining a pose for an object. A plurality of images capturing the object at different viewpoints are received. The viewpoints are related by an angular distance with respect to the object. A feature vector is extracted for the object from each of the received images. Each extracted feature vector is compared with feature vectors from a database to determine a plurality of candidate poses. A pose of the object is determined by comparing candidate poses associated with different ones of the viewpoints, using the angular distance between the viewpoints with respect to the object.

  • Patent number: 9230200
    Abstract: A method for combining layers of an image represented using an intermediate format receives at least two layers from the plurality of layers to be combined and estimates resources required to combine the received layers using a first combining operation. The first combining operation comprises at least rasterizing data of the received layers. The method attempts to combine the received layers using a second combining operation to produce an output in the intermediate format. In response, the method generates a combined layer for the image by combining the received layers in accordance with a selected one of the first combining operation (merge & flatten) and the second combining operation (merge). The selected combining operation is based on success of the attempt. Desirably the method is performed within a printer apparatus where limited memory and/or computing resources are available for image rendering which could otherwise limit the rendering of complex pages.
