An Efficient Batch Verifying Scheme for Detecting Illegal Signatures

並列摘要


In a batch verifying scheme, multiple RSA digital signa- tures can be verified simultaneously in just one exponen- tial operation time. Currently, the verifier could not easily detect where the signature-verification fault was located in most schemes, if the batch verification fails. In this arti- cle, we proposed a new batch verifying multiple RSA dig- ital signatures scheme based on a cube. The scheme can detect accurately where the signature-verification fault is located. Moreover, once the total number of signa- tures is fixed, the size of exponentiation operations is in- dependent from the number of illegal signatures in our scheme. Therefore, our scheme has a better performance and higher effciency than the previous ones. Finally, we described an extend batch verifying scheme under the con - dition of n - dimension.
