The batch verifying multiple digital signature scheme: A modified version of Ohta-Okamoto digital signature

In order to reduce the signature verification time quite, some investigations on DSA-type and RSA-type digital signatures have been done to achieve batch verification. However, in this article, we shall propose an alternative type digital signature, which is a modified version of Ohta-Okamoto digital signature scheme, to give an efficient batch verifying multiple-signature scheme instead of verifying one individual digital signature at a time.
