Abstract
A computer-implemented method of identifying a denial-of-service attack during a threshold signature scheme, wherein each participant has respective shares of first and second shared secrets, wherein the method is performed by a first participant of the group and comprises: calculating a first target share; calculating a target value based on the first target share and a first predetermined amount of other target shares; calculating a target public key corresponding to the target value; calculating a first verification share based on the first share of the first shared secret and a public key corresponding to the second shared secret; calculating a verification public key based on at least the first verification share and a second predetermined amount of other verification shares; and determining whether at least one other participant is attempting a denial-of-service attack based on whether the verification public key matches the target public key.
