N2 - Though group signature schemes with efficient membership revocation were proposed, the previous schemes force a member to obtain a public membership information of 0(lnN) bits, where ln., is the length of the RSA modulus and N is the number of members joining and removed. In the scheme proposed in this paper, the public membership information has only K bits, where K is the number of members' joining. Then, for groups with a reasonable size that is comparable to the RSA modulus size (e.g., about 1000 members for 1024 bit RSA modulus), the public membership information is a single small value only, while the signing/verification also remains efficient.
