> In recent years, increased reliance on computer security and the unfortunate fact of lack of it, particularly in the open-architecture computing platforms, have motivated many efforts made by the computing industry. In 1999, HP, IBM, Compaq, Intel, and Microsoft announced the formation of the Trusted Computing Platform Alliance (TCPA) that focused on building confidence and trust of computing platform in e-business transactions. In 2003, the Trusted Computing Group (TCG) was formed and has adopted the specifications developed by TCPA. The TCG technology strengthens the trust of the user into the computer platform

Because one of the biggest issues facing computer technology today is data security, and the problem has gotten worse because users are working with sensitive information more often, while the number of threats is growing and hackers are developing new types of attacks, many technology researchers advocate development of trusted computing (TC) systems that integrate data security mechanism into their core operations, rather than implementing it by using add-on applications. In this concept, TC systems would cryptographically seal off the parts of the computer that deal with data and applications and give decryption keys only to programs and information that the technology judges to be trusted. The TCG made this mechanism as their core criteria to define the technology specification. Operating condition and which is highly resistant to subversion by application software, viruses, and a given level of physical interference. The Trusted Computing Platform TCP operates through a combination of software and hardware: manufacturers add some new hardware to each TCP provides two basic services, authenticated boot and encryption, which are designed to work together. An authenticated boot service monitors what operating system software is booted on the computer and gives applications a sure way to tell which operating system is running.

This is done with the help of the hardware which maintains the audit log of the boot process.

On the computer platform with TCP, the TPM is used to ensure that each computer will report its configuration parameters in a trustworthy manner. Trusted platform software stack (TSS) provides the interfaces between TPM and other system modules. The platform boot processes are augmented to allow the TPM to measure each of the components in the system (both hardware and software) and securely store the results of the measurements in Platform Configuration Registers (PCR) within the TPM.

Trusted cloud computing System using TCP

As what we have discussed above, the trusted computing mechanism can provide a way that can help to establish a security environment. The model of trusted computing is originally designed to provide the privacy and trust in the personal platform and the trusted computing platform is the base of the trusted computing. Since the internet computing or network computing has been the main computing from the end of the last century, the model of trusted computing is being developed to the network computing, especially the distributed systems environment. The cloud computing is a promising distributed system model and will act as an important role in本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
