Algorithm 2

uploadRM.

(1)	Input: Uid, rule, sig
(2)	output: bool
(3)	% invoke by DMS to upload the role map rule.
(4)	% Uid is used to retrieve role mapping rules between DOs.
(5)	% Uid = ‘DMS_ID_sour-DMS_ID_dest’
(6)	% rule = {“role1,role2”, “role1, role3”,…}
(7)	%
(8)	DMS_ID_des = extract(Uid)
(9)	if verify(DMS_ID_des, sig)  true then
(10)	stub.PutState(Uid, rule); % store key = Uid, value = rule in blockchain
(11)	return 0;
(12)	else
(13)	return 1;
