| Abstract: | Based on CL signature,this paper gives a new type of divisiable e-cash system,which constructs a security compact e-cash scheme of high efficiency by including compact spending and bactch spending.It reduces the costs of the system as it's without TTP.The security of the scheme is based on the assumptions of decision Diffie-Hellman,the hardness of calculating discrete logarithm and the LRSW assumptions. |

| Keywords: | divisible e-cash constant complexity compact spending billinear pairings |
