Summary: Recently, \textit{L. Harn} [Batch verifying multiple RSA digital signatures. Electronics Letters, 32, No. 12, 1219-1220 (1998)] 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 improve his scheme.
