Proxy blind signature is the combination of properties and behavior of two most common digital signature schemes i.e. proxy signature and blind signature. In this scheme proxy signer generates the blind signature on behalf of the original signer without knowing the content of the message. Proxy blind signature can be used in various applications such as e-voting, e-payment, mobile agent communication. In this paper cryptanalysis of DLP based proxy blind signature scheme with low computation by Aung et al. has been done. An efficient proxy blind signature scheme based on ECDLP has been proposed.
