Abstract Designated verifier signature scheme has important applications in the security of network information, which make the verifier can not transmit a signature to any third party. The scheme can be used to strengthen the privacy of the signer, in which anyone can not verify the validity of the signature except the designated verifier. In this paper, a strong designated verifier signature scheme from Multivariate Public Key Cryptosystems (MPKCs) is proposed, the proposed scheme satisfies the security properties of correctness, non-transferability and unforgeability if the underling MPKC is secure against the known attacks such as algebraic attacks, linearization equations attack, rank attack, and differential attack etc.. Furthermore, a specific strong designated verifier signature scheme from multivariate pFLASH signature system is given as an example, which has an obvious advantage of efficiency. The main advantage of the proposed scheme is that it is secure under the quantum computing attack.
