The user encrypts his data with the one-time symmetric key, SK, which is created andprovided to the user by the TTPN which is trusted by the user. If they are different,the attestation fails. The root of trust for storing and reporting integrity metrics which is in the TPM isresponsible for storing and reporting the integrity metrics of the platform in the PCRregisters. Since cloud is a third partysystem, it cannot be trusted. The key pairdenotes the identity of the storage node.


Message 4 includes message 3 sent by the user, H Message3 pri N , the nonce of the node, nN, to avoid replay attacks and the ID of the storagenode, Nid. The cloud provider provides software applications to theclient and allows him to use them for as long as he needs [5]. After decryption of files, the node re-encrypts the files, the received user nonce, nU, andthe public key of the node, pub N , with the user key, UK, to achieve dataconfidentiality. Since the encryption keys and the user key arestored in the TPM, they are safe. The privatekey is stored in the memory of the node and is not saved anywhere. The usercontacts the front-end server, FES, to access his data. University of Kentucky Master's Theses. A crucial component of UKnowledge is providing publishing services to broadly disseminate scholarship created or sponsored by the UK community. Therefore, Cloud Computing is also known as utility computing. The trusted measurement root may also measurecharacteristics of another measurement agent before passing on control to it. There is a key hierarchy for all the keys which are used for protected storage within theTPM [3]. A storage node prepares a measurement list, MLN, which denotes the measurement ofthe current state of the system at boot time. Encrypted file systems workwell when they are used in personal computers. The TTPN compares this measurement list with the expectedstate of the platform stored within itself. The TTPN checks thecorrectness of the platform of a storage server, i. We assume that the key creation and management is done by the encrypted filesystem and it takes care of the encryption and decryption of data and storage within thestorage server. The front-end server forwards the message to 27 the TTPN. If they are not the same, the node identifies that the files are modified intransit. If they are different,the attestation fails. Finally, I thank God and my family for their never ending blessings for me. If the values donot match, the TTPN comes to know that the measurement list has been changed andthe attestation fails. The TTPN will not add that node to its ready node list. In thesame way, this second measurement agent may also measure the characteristics ofanother measurement agent, log the measured data, store the final result in a TPM, andthen pass on control to a third measurement agent and so on [1]. User keyProtocol 4Message 1: Private key of the storage node NUK: This is published as an Endorsement Certificate. ID of the node NProtocol 3Message 1:

  1. The data stored in a trusted storage server should be replicated onto othertrusted storage servers only.

  2. If they are different, theTTPN does not attest to the storage node. So, only the TPM can decrypt the secretdata stored in it using its key.

  3. When the TPM signs theplatform state stored in the PCRs using the private attestation identity key and sends itto a remote party challenging the TPM, the remote party retrieves the attestationidentity key certificate from a certification authority and decrypts the signature of theTPM.
