Abstract:
An attack detection apparatus includes a window size change unit configured to change a size of a window to be applied to traffic, and an abnormal state detection unit configured to detect an abnormal state of the traffic to which the changed window is applied.
Abstract:
An intermediate node and method thereof in a network determines whether to perform verification of content at an early stage based on information about the content. The method includes receiving, from a content requesting node in the network, a request for the content, determining whether to verify the content based on information, transmitting the content to the content requesting node without verifying the content in response to the determining, and verifying the content and transmitting the content to the content requesting node in response to the determining.
Abstract:
Provided is a method of authenticating and verifying data packet transmission, and apparatuses for performing the same. The method and corresponding apparatus are configured to encode data packets through erasure coding. The method and corresponding apparatus are also configured to generate authentication packets for the encoded data packets based on hash images of the encoded data packets.
Abstract:
Provided are apparatuses and methods of generating and verifying signature information for data authentication. A method of verifying signature information may involves receiving signature information with respect to a predetermined number of data segments from a transmitter, constructing a hash tree based on the signature information, and verifying a validity of the signature information, by verifying trapdoor hash values using a root hash value of the constructed hash tree.
Abstract:
A display device according to an embodiment of the present disclosure includes a display including an active area on which an image is displayed and a bezel covering edges of the display so that the bezel covers a part of the active area of the display. The bezel includes a transparent part that covers the part of the active area of the display and internally transports light emitted from the covered part of the active area of the display by reflecting the light, emitted from the covered part of the active area of the display, inside the transparent part and a reflection part including a reflection surface disposed parallel to one surface of the transparent part and reflecting light transmitted from the transparent part back into the transparent part.
Abstract:
Provided is a communication method for an administration node in a content centric network (CCN). The communication method includes receiving a packet requesting deletion of an invalid content from a requesting node that detects the invalid content, generating a content revocation list including a name of the invalid content and a period of time over which the deletion is to be performed, and flooding a data packet including the content revocation list to the requesting node and a normal node included in the CCN. Also provided are related communications methods for a receiving node and a normal node, as well as the nodes themselves.
