摘要： Exemplary embodiments of the present invention relate to a batch verification method for verifying a plurality of authentication data or digital signature values and an apparatus thereof. A batch verification method according to an embodiment of the present invention comprises: rearranging N pairs of individual instances which compose a batch verification instance; selecting N−1 verification exponents from a verification exponent set E which is used for the batch verification; and performing the batch verification for the rearranged batch verification instance by using the selected verification exponents. Exemplary embodiments of the present invention can be suitable for digital signature and cryptographic confirmation. According to exemplary embodiments, verification computation amount of a plurality of authentication data or digital signature values can be significantly reduced.
