摘要：There are several factors which depends on the billing system nonrepudiation capabilities must have integrity billing transactions, a minimal computation cost have nonobstructive. And the monitoring of service level agreement (SLA) should be provided in a trusted manner in terms of security capabilities of existing systems are limited and to overcome this drawback THEMIS is proposed as a secure and nonobstructive billing system, for supervision of billing the system uses a novel concept called cloud notary authority. The cloud notary authority generates mutually verifiable binding information that can be used to resolve future discussion between a user and a cloud service provider in a computationally efficient way. Moreover, to provide a forgeryresistive SLA monitoring mechanism, we invent a SLA monitoring module enhanced with a trusted platform module (TPM), also known as SMon. The performance evaluation confirms that the overall latency of THEMIS billing transaction (avg. 4.89 ms) is much shorter than the latency of public key infrastructure (PKI)based billing transactions (avg. 85.51 ms), though THEMIS guarantees identical security features as a PKI.
