SYSTEM FOR PREVENTING COUNTERFEIT AND FALSIFICATION OF METERING DATA IN CLOUD COMPUTING SERVICE

摘要

PURPOSE: An anti-forgery system for metering data generated in a computing service system is provided to verify the metering data by generating the metering data in a reliable method. CONSTITUTION: A reliability driving module(20) executes metering software installed in a cloud computing system. A TPM(Trusted Platform Module)(30) provides a security function for metering data generated by the metering software in a cloud computing service. The reliability driving module includes a TXT(Trusted Execution Technology) unit(21). A hash value of a program driven by a program list exists in the program list, the TXT unit executes the program. The TPM includes a tick stamp unit(34) by writing a digital signature in the metering data by generating tick information, a sealing unit(33), a monotonic counter(32), and a PCR(Platform Configuration Register)(31) storing the hash value.
