Two kinds of certificate revocation are analyzed,one is based on Hash algorithm and the other is based on a cursor tree of remainder valid period,then the advantages and disadvantages of both schemes are studied.This paper proposes a promoted certificate revocation based on Hash table and balanced binary tree,and gives the analysis of validity and sccurity.Compared with three kinds of certificate revocation,the result improves certificate revocation and reduces communicational cost.
