| Abstract: | By means of the interpolation polynomial on finite field,a construction method of a class of verifiable random number was given and the verifiable random number was applied to group signature scheme,so that an applied scheme of verifiable random function in group signature system was proposed.Then the security of the scheme was analyzed and the scheme was compared with other ones.The result showed that the scheme was anonymous,traceable,unforgeable and so on.Member adding and removing could be expediently r... |
