Abstract: A batch verification apparatus and method wherein, the method includes: generating a plurality of secret keys, a plurality of public keys corresponding to the plurality of secret keys, and a plurality of verification values corresponding to the plurality of public keys; calculating a first batch verification value based on the plurality of verification values; calculating a second batch verification value based on the plurality of secret keys and the plurality of verification values; comparing the first batch verification value and the second batch verification value; and determining that a batch of the received plurality of verification values is verified when the first batch verification value is equal to the second batch verification value.
