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.
