In an updating period, one participant randomly generates the EPR pairs, and the other participants update their key shares and perform the corresponding unitary operations on the particles of the EPR pairs. Then, the …

WebbAn asymmetric secret sharing scheme (A-SSS) can set the number of servers at less than k, because it makes up to k-1 shares from one key of the owner of the secret. Therefore, the secret is not revealed even if all the servers are attacked. However, when the owner's key is stolen and attacked, shares may be leaked. Therefore, in this paper we propose a …
