Cryptanalysis of the Batch Verifying Multiple RSA Digital Signatures

Recently, Harn proposed an efficient scheme that can batch verification multiple RSA digital signatures. His scheme can reduce signature verification time. However, there is a weakness in his scheme. In this study, we present two methods to against his scheme. Key words: cryptography, digital signature, RSA.
