Abstract: A notion combined the content extraction signature and the universal designated verifier signature was put forth by Lin in 2012. Specifically, it allows an extracted signature holder to designate the signature to a prospective verifier. However, existing designs become inefficient when multi verifiers are involved. To improve the efficiency, in this paper, we extend the notion to the universal designated multi verifiers content extraction signature (UDMVCES). Implementing our new scheme, the extracted signature holder can efficiently designate the signature to multi verifiers. Additionally, we provide the security notions and prove the security of the proposed scheme in the random oracle model. To illustrate the efficiency of our UDMVCES scheme, we analyse the performance of it. The analysis shows that the computation costs and signature lengths of the new scheme are independent of the number of verifiers.
