Quantum Threshold Signature Based on Divisible Quantum Entanglement and P Unitary Operator
Zhenhu Ning · viXra · 2014
Different from the existing quantum threshold signature schemes, which are mainly based on the classical Shamir’s threshold signature scheme, we construct the map from the multiple binary information to a quantum and support a new threshold signature scheme based on divisible quantum entanglement and p -unitary operator, which are well defined in the paper. Compared with the existing the schemes, the scheme involved fewer quanta. The scheme also meets the requirement of “Threshold Signature”, that is to say, only the number of participants is not less than the threshold, they can execute the signature or the verification.
