Risk Situation Assessment Model Based on Interdomain Interaction in Cloud Computing Environment

Algorithm 1

Comprehensive algorithms for risk assessment.

	Input V_User, V_D, V_Resource
	Output UFE, Cu, TEC
	Begin
(1)	Initialize RP_ECDM = (V_User, V_D, V_Resource, V_Time)/Initialize the cross-domain access control model/
(2)	Construct u, d/Construct random interaction information between user and security domain/
(3)	Construct a matrix of interaction information between users and security domains
(4)	Calculate the user and security domain ratings based on the interactive information, and see (9) and (10) for details.
(5)	Finally, the comprehensive risk value of the RP-ECDM model is obtained
(6)	Back UFE, Cu, TEC
	End
