Abstract: A new and practical electronic voting scheme is proposed by using bit commitment technology and partially blind signature which is based on bilinear pairing. In the protocol, voters were divided into the different category and we can count the view of different category. Voters keep the confidentiality of votes with bit commitment. Authentication center inserts the ID of privilege subsets into signatures, which can be used to distinguish different privilege subsets. Compared with the protocol of [4,5], Computational complexity is small，the round of voting is independent of the number of privilege subsets and can adapt many kinds of election.

Key words: electronic voting, partially blind signature, bilinear pairing, bit commitment
