  • Method and apparatus of data authentication
    Patent number: 9473307
    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.

  • METHOD AND APPARATUS FOR CONTENT VERIFICATION
    Publication number: 20150100668
    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.
