Since many applications require the verification of large sets of signatures, it is sometimes advantageous to perform a simultaneous verification instead of checking each signature individually. The simultaneous processing, called batching, must be provably equivalent to the sequential verification of all signatures. In eurocrypt'98, Bellare et al. [1] presented a fast RSA batch verification scheme, called screening. Here we successfully attack this algorithm by forcing it to accept a false signature and repair it by implementing an additional test.
