It is indicated that Cao Guoliang et al's multicast key management scheme based on generalized cat map does not satisfy the independent security requirement of individual keys of group members.A modification scheme was proposed by using one way function.The presented scheme satisfies the independent security requirement of individual keys of group members.Compared with Cao Guoliang et al's scheme,this modification scheme has higher security and lower computation and communication overheads.
