Abstract: The present disclosure relates to a method and apparatus for electronic signature and, more particularly, to a method and apparatus for performing safe, post-quantum electronic signature using infinite continuity of a hash function and one-time key pairs. A method for electronic signature using a computing device according to one embodiment of the present disclosure comprises obtaining a message to be electronically signed; obtaining a plurality of public keys generated by a key generation algorithm, and based on the plurality of public keys, generating a signature verification value for the message, wherein the signature verification value includes at least one verification factor generated based on the different public keys or a value obtained by merging the different public keys.
