Abstract

Provided are apparatuses and methods of generating and verifying signature information for data authentication. The 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.

Description

technical field [0001] The following description relates to a method and apparatus for generating and verifying signature information for data authentication. Background technique [0002] In order to ensure the secure distribution of content within a content-centric network (CCN) environment, a content distribution network (CDN) environment, and / or a peer-to-peer (P2P) network environment, it is desirable to verify the authentication and integrity of the content being distributed. Electronic signatures can be used to verify the authentication and integrity of content. The electronic signature can be generated using the signer's private key and can be verified using the signer's public key. However, since the generation and verification of electronic signatures rely on mathematical algorithms, it imposes a large computational burden on both the sender and receiver. Contents of the invention [0003] This Summary is provided to introduce a selection of concepts in a simpl...
