THE PRIVACY FEATURE OF TRUSTED COMPUTING TECHNOLOGY USING THE CONCEPT OF DIRECT ANONYMOUS ATTESTATION WITH CLOUD AS A TECHNIQUE

ABSTRACT The Trusted Platform Module (TPM) is a hardware chip designed to enable computers to achieve a greater level of security. In the Distributed Environment all the systems are connected together with a limited bandwidth security feature. The TPM module will increase the security feature by the concept of DAA. Direct anonymous attestation (DAA) is a special digital signature primitive, which provides a balance between signer authentication and privacy. A DAA scheme involves a set of issuers, signers, and verifiers. An issuer is in charge of verifying the legitimation of signers and of issuing a DAA credential to each signer. The TPM is the real signer and holds the secret signing key. Authentication can be applied at the level of the virtual private network (VPN). As a technique of cloud service the authentication to the distributed environment can be modeled with the Trusted Platform Technology
